- Fox MTB Fork travel increase 130 mm to 150 mm. How To. Trail Breaker
How to increase Fox mountain bike fork travel easy and cheap! I have a 2018 Fox Performance 34 fork with 130mm of travel. But this process will work for any Fox fork. All you need to do is buy a new air shaft assembly for your size fork (32, 34, 36 or 38) and swap it in for your current one. I bought mine at Worldwide Cyclery for $35!

Thanks - been on the fence about buying a Fuel EX. 140 travel is a little bit on the short side for my six feet/190 lbs. Thinking about buying the bike and doing the swap immediately (also hear it’s a good idea to service a new Fox fork before riding). Curious - any downsides to the increase as far as ride? Also, how does before and after travel compare once sag is set?
You’re welcome 👊🏻 Same here! I’m 195 with gear and 6’1”. If you buy a bike used open up the fork to at least clean it and change the fluid. It makes a HUGE difference even in a fork that seems to be good. Check out the complete video I did on a full lower service for FOX forks. Travel is the same after sag is set (was 130 before and is now a full 150). If the fork doesn’t return to full travel, you have air trapped in the negative air chamber unable to equalize. Probably too much grease used in the lower service blocking the transfer port. The only downside I’ve found is on long, steep trail climbs while standing. The front is noticeably higher and lighter making standing traction less. Seated is fine though...you just gotta shift forward on the saddle to keep that front wheel on the trail😁
Travel has nothing to do with your height and weight bro, all about the type of tracks you going on. For example you don't buy a trail or all mountain bike or enduro bike for XC. And vice versa
@@TrailBreaker hey man great video I gotta ask you I have a Scott ransom 910 2021 it comes with fox 38 170mm performance elite I’ve bought a kashima 38 grip2 180mm will it be fine that extra 100mm? Won’t affect the geometry?
@@ns671fryeah, I'm really confused why they're association travel with height and weight.
Dang, I wanted to do this in 2019 but it wasn't compatible beyond 140. Very happy to see that you can now get this amount of travel out of them! Excellent fork and video
Didn't realise you could extend the travel. Glad I found your video, you've just saved me £££'s buying a new fork
Thanks!
I’m glad to help. I really like my bike with the extra travel. If I didn’t, I could go back and only be out $40!
I’ve watched this like 3 times a just now realized this is my local trail. Big Creek
Dude, That bike's gonna crush it! Thanks!
Thank u for sharing Sir! Now I found me a good winter project for my Fox 36 performance fork (160mm to 170mm)
Sweet!
This is a great video. Concise without any blah blah blah. Be wary folks, make sure your damper can go the increase. 120 or smaller forks usually need a damper replacement also. Fox can confirm for you.
Great video, now I have to buy all that stuff to service my fork for myself. Keep it up, greetings from Mexico
Hello! Yes but then you'll have it forever and can help your friends!
I just completed this modification for my 2019 Vanquish with 120mm fork. I actually picked up both 130 and 140 parts. Your video was short and sweet and helped me complete this modification. Great job. Oh, I'm running 140mm with 2 spacers and slightly lower air pressure and loving it (was running a single spacer). The additional sag allows for better small bump absorption and ability for the front to maintain traction better over ripply areas. Love this mod. Whatever I may have lost in terms of steering response with slacker HA and higher BB (pretty tiny), I've made up with running more sag and keeping front tire more planted and helping to soak up some of the hits on my HT.
That's awesome, Paul! That has been my observation too. I was running it very firm at 130 mm with max spacers (6.) At 150 mm I am using 3 spacers and more sag. 100% better!
exactly the travel I was looking to upgrade to. Ty
You're welcome
I just bought my first serviceable air fork a Rockshox Recon LC and to be honest it had me worried about maintaining it but after watching a ton of videos, including this one (I know this is a Fox fork and not Rockshox) servicing these air forks seems pretty simple.
Awesome! Just take your time and keep track of your parts as they come off.
Thanks for another great video tutorial! I have a FOX 34 on my Salsa Pony Rustler that I want to extend the travel on from 130 to 140mm. I'd go to 150 like you, except there is a warning on my bike's frame sheet not to exceed 532 for axle to crown length...which just happens to be the length of the FOX 34 140mm fork.
Should be a safe bet.
Very helpfull video, thank you! i have the exact same bike with the same thoughts. did you make changes to the psi and rebound clicks? could you help me with this info to start my setup?
About to do this exact conversion on my ST Stumpy. Good to hear you love it. Hoping I can then drop it back into the slack position on the flip chip and still have good BB height.
Yes. If I dropped the mino link to low it’d prolly be what I had in the high position with a 65 degree HTA. But I like it where it is now 😊
Did you ever go through with it?
Hi great video. Just wanted to know did you change the length of your brake hose due to the increased travel?
Have a Trek Fuel Ex 9 with the Fox 36 fork with 140 mm travel stock, but upgradeable (according to Trek) to 150 mm without adversely affecting the geometry. Might also throw in the Grip 2 damper while I'm at it. Next time I service the fork, maybe next spring, after a winter of mud slogging.
Solid! You'll love it. This bike NEEDS 150mm up front. Even in the high position the BB is too low
Because of your video and a few months of research, i went from a 32 120mm up to 36 150mm. Its has completely transformed my bike, especially the BB height. I was getting pedal strike here and there. Now i get none! And the jump of 30mm feels so much better. There is a slight weight penalty, maybe slight angle change but on the trails its not noticed. Any negatives are vastly out weighed by the positives.. the bigger forks dont make the front end look lopsided. It looks perfect and badass!
Nice work!
Thinking of the doing the same with my bike! Do you still like it? No problems at all?
@@TheAbelardo17 love it! Will never go down to a 32 or 34. But, I do live in the mountains of western NC and the trails are extremely rough. Im on an aluminum hardtail so it works for me. Research before you drop a $$grand.
@@neuregel thanks bro! Yeah been looking for a use fork rn I’m running 120 but wanna get a 140
Hello from France.
You can do the same for the rear shock?
Thanks
This video is just what I was looking for. My code came up as a 2021 Rhythm Series 34 FLOAT 29 140 Grip. It’s 150mm travel on 27.5 but 140mm on my 29er. I’m wanting to make it 150mm on 29s would that mean I need the 160mm kit? On the fox site it says “27.5 only” for 160mm so I’m a bit confused.
If you mix sram butter and fox 20wt and add a few drops to the top of the seal head it makes a big difference and lasts much longer. If not the grease just piles on the plastic and never touches the seals.
Good to know. Thanks!
How much do you tighten the bolts after the service?!?! I haven’t found any info on it! (UPDATE: Never mind I found the info on fox’s website and they said 5.7nm or 50 inch pounds for the Fox 34 2016-2021)
what the limit on variance from stock? so, can you take a 120 all the way to 160? or do you have to change the stanchions at some point?
nice video man!!! i've a scott spark 120 rear and i wanna try 140 front. what do you think about? spark (no rc) and fuel are similar on the geo. Beside slack seat tube angle, i see only positive change.... any thoughts?
Go for it! I LOVE how my fuel feels now. I just moved my saddle forward about 1-2 cm and that puts the effective SA about where it felt before on climbs. I added volume reducers in the shock since it was way too easy to bottom and is now nicely balanced with my longer, plusher fork. Before I ran the shock really firm (20% sag) and the fork maxed out with volume reducers and firm (20% sag too). No bueno. On a typical ride I use 90-95% rear travel and about 85% front. This feels perfect and well balanced. Let me know it you make the change and if you like it👍👊
Curious what your head tube angle was before you made the switch? I am thinking of updating my fork from 130 to 150 to make the front end a little slacker; currently my HT angle is 67.5. I'm hoping for around 65, but that's probably too much for this update. Thanks for the vid! Simple and easy to follow!
About .5 degrees depending on the amount of sag. I also added a .5 degree spacer between the HT and the fork crown. AND Mino link in slack. I’m now close to 65 degrees which I like. Hope this helps
Great vid 150mm is the best
Thanks! Probably the top end of “trail bike” category but I 100% agree. 130 mm just wasn’t enough room to balance initial ride comfort and bottom out. Either too much PSI (too rough initially) or way too progressive. This is the sweet spot😁👊🏻
@@TrailBreaker do you feel like your geometry is messed up or it ride fine?
Great video, I have a 2020 Fuel EX 9 and plan to do this upgrade when I do my first lower leg service. Is there any cheaper alternative to the Fox seal tool? Or should I just bite the bullet and buy it?
Thanks! I went cheap but wish I hadn't. The real Fox tool prevents you from over-driving the seal into the lower...foolproof.
Good stuff. I’m about to go from 130 to 140 on my Rockshox Recon.
Sweet!
@@TrailBreaker well I did the increase to 140mm on the Recon then found a good deal on a 130mm Fox 34. Rode it that way for a few months but now I finally did the increase to 140mm on this one. Thanks for your video!
@@downtoridemtb How did you like the jump from the Recon to the Fox 34? I have a Recon 130mm and don't like it much. Feels barely better than Suntour, no matter what I do to it. I don't want to spend too much on a fork upgrade, as I plan on upgrading to a longer travel bike altogether in the semi-near future. Thanks!
@@ABHORRANCE831 yeah I like it. Improvement, yes. Huge improvement, probably not. Definitely a better feel over repeated impacts from rocks, roots, etc. The one I got was a Rhythm which is original equipment only so if you got a Performance I think it would be even better. Just keep in mind I’ve never even ridden anything better so my point of view may be slightly skewed.
@@downtoridemtb Good to know! I've ridden several demo rides with Fox Factory forks, some I absolutely loved, others I found not to feel a lot better than what I have... Granted this was totally about how someone else had them set up. I rode a Rhythm on a loaner bike for a couple months recently, and found it excellently plush on big rock hits, but very jarring on rapid, hand rattling rutted out terrain (I'm guessing this is where being able to dial in high speed and low speed rebound would be super sweet).
I just got a 150mm fox float for my giant Trance. The bike came with a 130mm fork. Should I expect any major steering changes with 20mm increase?
Waiting on a crown race so I should find out very soon I guess. Great video!
You will notice the tight turns will be slightly harder due to the slacker HTA and increase in trail. But it is very slight. On the flip side, high speed descents and gnarly trails are calmer. You’ll love it 🤙
Super Video. Wie finde ich heraus wie viel Nm drehmoment angezogen werden muss . Vielen dank
Awesome video!! What is your mino link setting after increasing travel. High or low?
Thanks! Always high. Tried low when I first bought it and pedal strikes were constant. BB is about 1 cm higher now and feels right
Great video. I have a new Frameset. My fork is from early gen Primer Fox 34 Performance Elite. My new frame is designed for an OE only Fox 34 @150mm. Since I’m using my old fork I’m noticing pedal strikes and knew I would need to replace the air sleeve with a longer one. I ordered a 140 rather than 150 because at 215 lbs I was worried 150 might be too flexy. I plan to install in next few days. Any idea how much an increase in 10mm travel will affect BB height and HTA? I’m thinking 1/4 inch higher BB and 1/2 degree slacker HTA. Any thoughts? It is a 2020 Primer and will be 140/140 with DPX2 shock. Thanks
Thanks! I feel your pain with pedal strikes 😊. I think your estimates are spot on. My swap added .5” and 1 degree less HTA. 10mm should be half that. I wouldn’t worry about the flex on the 34, maybe a 32. The big benefit of the 36 is lateral stiffness for aggressive riding where you’d really notice the deflection during crazy DH runs. I push mine at 195 and can’t feel any flex (but I haven’t tried a factory 36). I would personally go 150 and see how it rides👊👍
Great video, performed exact same conversion to my Trek Fuel Ex last week. Removing volume spacers from 130mm setup added grip.
After tuning what percentage of sag did you settle on?
Thanks👊🏻👍🏻 30% with 3 spacers. Before I was at 20-25% and 6 spacers. Rarely bottomed but ROUGH as S#!t! And no traction. 195lbs rider wt 220psi and 3 spacers for aggressive rides. 2 spacers may be good for trail riding
@@TrailBreaker
Cheers, I trialled 25% sag but planning to test with -5 or -10psi. Was concerned about it getting a bit spongy under brakes, taking your advice I will adjust before next ride and take my pump with me
Cheers
@Nathan Port what fork do you have? Got a Rockshox 35 Gold 140mm on my Fuel Ex7, thinking of bumping it to 150mm. What you reckon do I need to install "Bottomless Token"?
@@dzennatienza353 I am using a Fox 34 which requires a new air shaft. RockShox you may be able to remove spacer?
Don’t forget that many bike frames have a maximum travel size. If you change it too much it can put stress on the head tube, and is then evading any warranty it might have
You are absolutely correct. I think I'm still of with this since tis bike came spec'd with 140mm fork if it was 27.5+. Either way, it's way out of warranty anyway 😀
@@TrailBreaker lol yeah general rule of thumb is 10 more or less is fine I know that’s true for treks
If you are going to over fork 20mm…you are definitely gonna jack up the geometry. Yes the head tube angle slackens but that over forking also slackens the seat tube angle and makes the reach even shorter. It won’t pedal or turn as good with the higher BB.. Sure it will take bigger hits. That’s the only pro. Rest are cons.
Best advice, use an angle headset (Wolftooth has a decent one) so your are not messing up that precious geo on the rest of the bike. Check with Trek warranty first
All good points. It’s been a while with this setup and I gotta say I like the bike way more with the new jacked up geo. BB was always too low and I just slid the saddle forward about a cm. Turns just fine. Thanks for watching!
how can i do this on my fox 32 step coast 29 120 fork i couldn't find suitable parts and i guess it's not possible
Great video. How do I find out how much Nm torque has to be tightened. Many Thanks
Probably the Fox website
what watch is that you wearing ?
Would this work on lower end forks? I’ve got sr sun tour. Xcr32 airs? Great vid
Possibly. Do a search for air shaft replacement and ask the company if you can
Nice
Great tutorial, I have same bike and was just looking to service the fork but now I want to increase the travel too, mine is already at 140 so my question is did you have to buy a new 160/150 travel air shaft or the 140 plus the spacers will do it alone? Thx
Thanks! Just an air shaft swap for the performance fork
@@TrailBreaker is your fork a Fox Rythm or Float? Mine is a Rythm and not sure the upgrade will fit cuz all the parts are fot Fox Float
hello there! this is for my hardtail. Its a 2021 Giant Fathom. Fork is garbage, a giant crest 34, 130mm 44offset. I bought a take off RS Gold 35 RL, 150, 44 offset for a very cheap price. Will a 20mm bump up give a hardtail stress on the head tube? i ride mellow to aggresive. both forks are 29er
thanks
Simple answer....No. your bike pivots off your rear axle and any stress is soaked up by the extra suspension. On my hardtail i went from 120mm to 150mm its better than perfect.
thanks for the Video,
Currently with my trek and 130mm travel the climbing is easy. with the 20mm increase in height at the fork, how does this affect climbing?
Very slightly. I slid my saddle slightly forward on the rails to keep the front weighted and climb with my arms more bent. On really steep stuff the wheel will want to wander a bit but, all in all, way better overall!
Hello. Great video. I have a trek fuel ex 8 2019 bike, there is a fox 34 rythm and apparently there is an opinion that you cannot increase the stroke of the fork because the upper legs are shorter than in the older models. Do you have any information on this?
Go to the ridefox.com site and enter the code on your fork. See what other travel options there are. Are you at 130mm? Also try googling 'fox 34 rhythm air shaft' to see what's available. I bought mine at Worldwide Cyclery but JensenUSA might bee good too. Let me know what you find👍
@@TrailBreaker where can I find that code and how should I know that other shaft is compatible with mine fork? I have 2017 Fox Float 34 Rhythm 130mm and want to increase to 140.
To all the expert out their, I’ve been biking for a couple years, I have a 2019 stache 5. Im going to start upgrading it. Im thinking when I do the fork to increase from the stock 120mm to 140 mm fork. Any thoughts? Would I need to go down to a 27.5 if I did this or would the 29 plus be ok?
Check the max travel that Trek has got that bike. Too much travel on that frame will completely hack up the geometry and how it rides. Just get a better 120 fork. Fox 34 Step Cast or something.
can this extend to 160?
Can you tell us what was your initial head tube and seat post angle and what seat tube angle did you end up with?
HTA went from 66.5 to 65.5 and STA slacked about a degree too. I love the HTA now and just brought the saddle forward on the rails about a half inch. Perfect!
Did you have to change your mino link setting at all… Do you have it in the low or high setting after fork increase..
I was able to finally put it in low
How do you check the part number for the replacement air shaft? Been meaning to do this to an OE fork I have. Thanks!
Go to www.ridefox.com/bike/help enter 4 digit code on fork click “get product info” click “part and drawings “ select your part
@@TrailBreaker Thanks!
Will this negatively affect the way the bike rides considering the frame is only made for 130mm travel? I'm thinking of doing the upgrade, but im a bit worried about possibly damaging the frame if I increase the travel. I usually ride drops upto 4 ft, tabletop jumps, and difficult technical sections, so I would be worried about the the extra stress on the head angle. Riding a norco
There's always a chance but once you're slightly into the travel the geometry is identical but you had a more gradual impact to get there. I had to run max tokens before and it was rough! Now I am using 2 volume reducers and more sag. I still use full travel occasionally but it's a lot more controllable.
@@TrailBreaker thanks
How much travel do you have in the rear? I have a Canyon Neuron CF 8.0 with 130mm front and back but I think I would benefit from getting the bottom bracket in a higher position and also a little more travel in the front wouldn’t heart.
130 mm. This raised my BB about .5” and makes the bike sit up better
@@TrailBreaker Forgot to ask, what was your initial head tube and seat post angle and what seat tube angle did you end up with?
Thanks for the vid. I'm planning on doing the same to my trial bike. Nice trails, where that at?
Thanks! It's Big Creek Park in Roswell, GA
I have a 2021 Fox 34 rhythm 140mm is it possible to go to 150mm on this fork? Can’t seem to find anything on it? Also would like to swap out the grip damper to a grip2 damper. Are both of these do-able on this model?
Go to ridefox.com and enter the code on the back of the fork leg. Here you'll see the different lengths available. I don't see why you couldn't swap out the damper.
Is part # marked anywhere on the airshaft itself? I bought a used fox 34 fork and I’m not too sure what size I have inside.
I'd just measure the exposed stanchion from the dust seal to the crown with no weight on the bike. Should be pretty close.
Hi! Thanks for your video. I tried to change 150mm air shaft on my 2020 Fuel Ex 8. However, I didn't dare to change it because damper side was shorter than air shaft after I installed 150mm air shaft. What do you think, should damper side be longer than air shaft that it will work correctly? Would you dare to install 150mm air shaft in place of 140mm on my situation?
That's interesting. My 2018 was no issue as the damper allows for slightly longer travel. Is the damper wide open and fully extended? If so, you may need to change the damper assembly to a longer one or modify the shaft on the one you have. I've never taken mine apart but it shouldn't be too bad. Just video the process so you'll have evidence on haw to put it back together😀
Hi. Thanks for your reply. Damper is fully open.
I sent email to Fox and asked that what do they recommend me to do. 😀
@@jan-martinnummensalo2433 Hi, I have a 2019 ex8 with 34 float. Did you get any answer from Fox? I have a feeling I run into the same problem as you.
@@mikaelniklasson7293 Hi! Thanks for your message. Nope, they didn’t answer to me. 😀 I sent few emails without any reply. 😀 I called in two Fox service store here in Finland and both dealers recommended to keep the original air shaft than change the 150mm shaft. 😀 Now I’m looking new 36 Fox for my fuel ex..😄
@@Jansapansa Thanks for your replay. After some Google searches I’m pretty sure that Rythm forks is not compatible with this upgrade.
Maybe I also buy a 36 insted. Good luck!
Was this bike a 29er? One site selling the air shaft says the 29er forks can only go to 140mm max. I have a 130 now. Thx
check your fork serial no with their website.. it will give you available upgrades
question.... I have a 34 rhythm 2017 of 100mm and I want to change it to how it was before (150mm) I want to buy the air shaft but I want to know if it would fit the air shaft of 2019 34 float of 150mm
Go to ridefox.com. Enter the letter-number code on the back of the fork to see if your fork comes in that travel option
What’s the part number and cost of the new 150mm air shaft? Nice job btw
Go to ridefox.com and enter the code on the sticker on your fork. There you'll get the part numbers for every part as well as fluid types and capacities. I think it was less that $40
Got a sub from me great video
Thanks, Ev B! I appreciate the support👊🏻👍🏻
I am with rock shox recon silver tk solo air 100mm travel is it a good idea to change it to 130? And can it end my fork?
You'll have to check with RockShox on the ability to swap it. My guess is probably not
Is there anyway that the seat tube angle wont get affected drastically
If I ran the mino link (the frame geo chip in the rear linkage) in the low position initially and THEN put it in the high position after the fork increase I’d only increase the seat tube and head tube angles by a half degree. Otherwise then slacken by a degree. I slip my seat forward a bit on the rails to keep my weight forward on climbs.
Can I replace my rear shock with a longer travel one ? And if so, how do I know the max length for the frame ?
as far as I know that is not possible because the max length is determined by the frame's design
Do you have before (130 mm) / after (150 mm) head tube angle measurements?
It’s about a degree
Hello, I want to ask you something, I also have a fox 36 and my question is, I want to go from 160mm to 140mm, what should I change?
Go the the manufacturer tech info site. Fox is ride fox.com. There you’ll see if the fork is compatible with that travel amount. If so, it’s usually just the air spring on the non-drive side opposite from the damper
Hey man, how is this holding up after a year? And also you mentioned it still climbs pretty well, but how does it climb compared to before with 130mm travel?
Still awesome. On steep climbs the front will get really light and even lift off the trail. I just need to lean my upper body forward by bending my arms to keep it planted. A very small price to pay for the benefit.
@@TrailBreaker I got impatient and ended up doing the upgrade before you replied 😀. So much worth it like you said. It only laste for 2 rides before I clipped a tree going downhill and had a massive accident. Now my confidence is back to zero 🤦
@@supositorio Man, I’m so sorry! Heal up fast and get back out there!
I have a 2014 evolution series CTD 34/140, is it possible to make it a 160 ? I can find a damper that is that long, but it says for 2019 and newer, will it work ?
Based on the year restriction my guess is no. But check with ridefox.com to be sure. Good luck!
hi i have fox suspension 34 float performance boost fork 120travel 29er i want to add the travel to 140mm it is posible?need your advice thanks
It should be. Go to the ridefox.com site and see if there are part numbers for your length and others. then it's just a swap like I did
I have a Fuel EX 8 from 2018, it is equipped with a Fox Rhythm 34 Float. I searched into Fox website but found no chance to upgrade to the upper travel; maybe the update is only for the Performance series forks?
That is very likely
Did you ever find an answer to this? I’m in the same boat.
@@logansmith2624 The short answer is yes, with a new Airshaft. The Fox 34 Rhythm and Marzocchi Bomber Z2 AirShaft kit will work, or a Fox 36 Rhythm and Marzocchi Bomber Z1 AirShaft kit, depending on what fork you have.
I got the following response from an online bike parts store:
"For 2016-2020 Fox 34 Float forks, this is the air shaft needed to change the travel.
110-140mm shafts fit Factory and Performance 27.5" and 29" models, 150mm-160mm shaft is only compatible with 27.5" models"
I currently have a 2020 Fox Float Performance 34 140mm and I want to increase to 150 mm.. But they said because I have 29" it is not compatible. It looks like your current bike is 29" and you didn't have any trouble increasing travel. Can you help me out?
Mine is a 2018 Performance 34 in 29er. went from 130 to 150 with no issues
your left shoulder have a bumb, did you have a 3 grade ac joint separation injury in the past?
Yes. Good eye. Grade 3 2 years ago.
@@TrailBreaker i have this same injury 7 months ago and surgery. How is your shoulder no issue ?
Is it safe to adjust to 150 from 130 using 32mm staunchion??
If they make a kit you can buy it should be fine. The only issues may be with the bike head tube
I have an orbea laufey 2019 with a fox 34 130mm would i be completely mad to increase the travel to 150mm its just 20 mm 🤔 I am also looking at fitting a luftkappe air piston modification. Should I go 150
The usual recommendation is 10mm max but I did 20mm and I think it improves the bike in many ways. It raises the BB about a half inch which is great since it's pretty low even with the mino link in the high position. Little slacker HTA (about .5") and the increased travel are obviously good. I offset the slacker seat tube angle by adjusting the saddle forward a little bit. Only downside is the added stress on the frame's HT but I'm willing to risk that since I use it primarily as an aggressive trail bike not enduro. I'd do it! 👊
Thanks for the reply ill try it I can always reduce if it doesn't work 🤣
@@TrailBreaker what are the chances that it will actually damage the frame from stress on the headtube?
@@clmfilms8103 Well, there’s always a chance. But the next year model bumped the fork to 140mm with no change in the actual frame and I’m going 20mm to 150. I think any damage I do will be from MY nonsense and not the over-fork. Either way I’m ok. It’s worth it. At 130 I had very little travel to play with for tuning and had to go really progressive and firm. At 150 I can remove some spacers and just use 30% sag and a little low speed compression
So to increase or decrease travel, just add or reduce some of those spacers?
No. The spacers just affect how the fork responds to big hits. Less spacers make it more linear where more spacers cause it to ramp up as you get to the bottom of travel. For travel changes you need to swap out the air shaft.
@@TrailBreaker perfect. Thanks for the info.
So maybe a weird question but I'm having a hard time researching this one on the web. I've seen several forks being sold and advertised that they can have their travel changed from say 150 down to 130mm.. I'm wondering if those forks are designed that way and that is what the manufacturer would do or if you were to buy a fork from a manufacturer that was 150mm travel and made it a 130mm travel would that newly transformed 130mm fork be different than a 130mm fork bought from the manufacturer.... Maybe a difficult way to word the question I know.. Been struggling to find an answer. Thank yoi
Great question. I believe forks that are 130-150 mm share the exact same lowers and uppers but just have a different air shaft. Same for some 160-170 or 180 models. It allows manufacturers to carry fewer parts to cover the lineup.
ask Fox themselves- they have an amazing customer support and exactly know what is possible and what it isn't designed for
Will this work on the fox rythm 34?
I just sent a message out to fox asking if I need to use a different air shaft but if you have that answer that would be great.
Thanks
I'm not sure about the Rhythm
idk if you got your answer already, but im pretty sure you can
Just found this video and this comment.
I also have a 34 Rhythm (130), any news about a possible 150mm upgrade?
Fox seems not to respond on e-mails…. 🤔
Thnx in advance.!
@@joostdeen9614 Yes you can. You need a Fox RHYTHM 34/Marzocchi Z2 AirShaft kit. I think 150mm is the max for a 34mm stanchion. Fox Performance of Factory have their own Air Shafts that won't fit.
Just found out that my 2022 model had a 140mm max. Planning this for next month, thnx 👍🏾😄
what trek model is this? i have fox 34 rhytm 140mm i want to decrease the travel for 20mm, is it doable what do u think?
Fuel 9.8. I don't see why not
I’ll trade you my fox 34 rhythm with 130mm of travel
Can you do this on any fork
No
Is this a 27.5 or 29? It doesn't seem that I can do the same on my 2021 Fox 34 29
29. What’s you travel?
@@TrailBreaker Fox Rhythm 34, Float EVOL air spring, GRIP damper, tapered steerer, 44mm offset, Boost110, 15mm Kabolt axle, 140mm travel
@@TrailBreaker was told by fox that the upgrade air spring will only work on the 27.5
So... what did you actually change to increase the travel?
Just the air shaft piston in the left side fork tube. The damper stays the same.
My 34 came with 150mm. Is it possible to convert it to 160mm?
I think I saw air shaft options at 130, 140, 150 and 160 for this fork
@@TrailBreaker 😃
I’m looking to lower my fork from 150 to 140. Too much for a 130mm frame.
Exact same process.
never compress with pump on
I haven't had issues. What does it damage?
please
at no time does he tell you that to be able to go up to 150 travel the damper has to be able to handle 150 travel, just putting a longer travel spring in the fork is not all the story
No dice even trek says not to go up more than 10mm or warranty is void! 👎🏼
Well, this bike can be run as either a 29er or 27.5+. The 27.5+ bike comes with a 140mm fork. And the new fuels come in 140, I believe. Warranty? I bought this bike used a year and a half ago. Fun always comes with a risk. I'm OK with this risk. However, I do think 160 would be too far😀
