Thanks for watching
You have saved my bacon with this tutorial m8, I thought I had to buy another derailleur. I have also watched few of your tuts, thank you very much m8 👍
Inspired by this and similar vids, I changed the 11-28 for a 11-34 on my Felt CX bike. Kept the short/med cage 105 but used the Road Link and also subbed a 34 tooth chainwheel for the 36. Didn't even need to adjust the chain length. Now I have the 1:1 lowest ratio. The rest is up to me.
Very good information. I currently need the extra gear of 34t on rear as I am climbing steeper grade mountains. I'm however using a R8000 ultegra front derailleur and rear derailleur in mechanical setup. My front is a compact chain ring set. It's been since 2018 since I used the 34t rear cassette, so I needed a refresher of what is allowed so I came here to this video. Thank you for this.
This re-assures me for my upcoming installation of 11-34t cassette to my 105 groups with Shimano 105 GS derailed to complete the change to use my Cannondale synapse carbon disc for gravel. Bke accommodates wide tires, just wanted to bring the 105 gearing up to the max for the gravel climbing so I'll end up with 50/34/ 11-34 or 1:1 34/34. So now the Winter bike has a use in the summer and takes away the temptation to buy a gravel bike for a few rides a year. Great video!!
u use a medium cage or short?
Subscribed. Thanks for sharing. The video title was bang on. Found exactly what I was looking for.
This guy is the best on the web for road bikes tech stuff
The short cage is really a medium cage. Not like the short cages we ran in the good old days.
Great videos that are concise and thorough. Keep up the good work.
Thanks!
Thanks mate! Just the vid I was looking for. Cheers :)
This was brilliant! This saved me having to buy a new derailleur. New chain is much easier and cheaper. Thank you.
Great video mate :) I run an 11-34 with my DA 9150. Runs flawlessly, even on the 50 front (tho I don’t cross chain the 50/34). My wife runs and older 6800 Di2 system. Was able to also get it to run a 11-34 with a swap to medium cage a friend had and a roadlink I had 👍🏼
you need to be very careful with Di2 going over the recommended limits - Most Di2 installation steps are similar to those of conventional mechanical groupsets, with one big exception: derailleur limit screws. If these are set too tight or restrictive this can cause extra strain and battery usage for both the rear and front derailleurs. I have drained my battery with 11-32 on SC and it took long to understand why.
Ramunas Macius all good mate my limit screws I reset with. The cassette. No battery issues since I did the conversion 5 months ago but handy to know thanks :)
Very concise and informative, thanks very much, you have just saved me buying a longcage derailleur!😁
Very helpful video....as always. And thanks for showing the comparison chart at the end.
Very helpful, clearly explained. Many thanks and happy cycling.🚲👍
So funny story 😅😅 I just installed a 11 - 36 CS-M771 cassette right now with a Taigra short cage derailleur. It actually works ok, the front is 42 - 52. Using the 52 front and 36 back doesn't sound that good though. But avoiding that I just went for a nasty hill climb bike and it's good. I actually have the Tiagra mid cage derailleur coming so will be changing to that and also replacing the 42 front with a 39 :)
I came from a Ultegra 11 - 28 for the cassette. I used to have that FSA crank and chain rings, but the crank died so I swithced to an Ultegra crank but it can't have as smaller chain ring. I couldn't do hills at all with the 28 and 42. 36 and 42 is good, 36 and 39 will be heaven haha
Thanks, I looked at that and it led me here. I’ll research to see if it will work. I go long so afraid of mechanicals miles out you see. Btw excellent channel 👍
Thank you my friend.
this channel is amazing!!!
I have 48/32 (Praxis) chainring and want to switch my 11-30 cassette to 11-32. Front derailleur is Dura-Ace (9100) and rear derailleur is Dura-Ace (9100). LBS says rear derailleur will not work for 11-32. What do you think?
The derailleur will work fine with the 11-32 cassette!
I have a Trek Emonda SL6 Pro Disc with Ultegra R8000 11s groupset. 52/36 and 11/30 and Short Cage Derailleur SS. I am having issues climbing in this ratio and hence bought a 50/34 and 11/34 cassette and a new HG701 11s chain. But I really don't want to spend on buying a new rear Derailleur and I am not able to find just the cage locally. Based on this video I can see I don't need either. Can you please confirm if my setting should work with the current SS Derailleur and why exactly then it's mentioned to use a Medium Cage?
I have exactly the same bike/groupset. Currently running 50/34 11-32 gearing that I have upgraded from the stock 52/36 11/30 (I live in Scotland and we have lots of lovely steep hills and headwinds 🤣) but after using 12s Ultra Di2 in Spain with a 34-34 lowest gear I’m going to swap the cassette again to an 11-34. The reason why Shimano state 30 is the largest sprocket is due to excessive safety factors and avoidance of potential court action from customers. Their chain wrap numbers are famously very conservative so 11-32 is considered the actual general max cassette size. Stretching to a slightly larger 11-34 is the same as going 2 teeth up rather than 4 if that makes sense?
Very informative video. I purchased an ss ultegra r8knwith an 11-28 cassette. I was thinking to change to an 11-32 but after watching this, I would go for a 34. I will have to measure the chain if I have to extend. Following your channel 👍🏻
Thanks
I just got a brand new gravel bike with 11-34 cassette and “Motobecane” (now a Taiwan company) managed to achieve NO clearance between the cog and the derailleur in the lowest gear. The cassette and pulley teeth are trying to go through the same link at the same time!
Ceramic speed goes on Ultegra Deraileurs.This will be a great setup for speed and hills.
This is helpful. I have just got an 11/34 and 50/34 and hoping I can use a short cage on that with some B screw adjustment?
Is the same true for a 105 RD7000 SS? My problem is my freehub body is older type that can only accommodate up to 10speed cassette…. But if I use the 11-34 cassette, I can make it fit the freehub but bot sure if the rear mech can shift all the way… I see you are using an Ultegra RD8000, so I was wondering if it is the same for a 105 RD7000. Thanks.
Good review
Nice video and nice accent.
Just found your channel! Certainly helps a lot and I wish ya great success with more vids styled just like ya do! tysomuch
I remember using even claris with 34t biggest cog with no problems.
Hey I ride a 50/34 Shimano 105 chainring and a 11/28T Cassette. Can I change my cassette to a 11/32 and not have to change my rear derailleur or chain?
czcams.com/video/Is4wAEBNkFc/video.html
Thanks for this informative test. My only concern is: does the RD SS capacity enough to tension the chain in "small-small" position, and not to overtension in "big-big" position? Did anybody tested it and can confirm?
G'Day, I have a R7000 11-34 cassette. I would like to know if a R7000 short cage derailleur also works for 11-34 Teeth？Many thanks!
Simply, brilliant. My bike has a 53/39 crankset and a 11/28 cassette, I have read some instruction manuals from shimano and they suggest to calculate the range (sum of the differences between crankset and cassette) to see if the rear derailleur has the capacity depending on the cage (SS or GS)... Could I move to a 11/34 cassette just with your method or should I replace the SS cage for a GS (keeping the crankset... -chain replacement is necessary to what I understand-)? I would like to have a more "versatil" bike because when climbing up, it makes me suffer (a lot) :')
thanks in advanced.
Change the chainset to a 50/34 that will make a much bigger difference to the bike than just changing the cassette!!
Hello I just fitted a 105 R7000 GS but when on small rear and small front the b-link on derailleur does not touch the frame hanger as there is chain sag. I have to adjust the derailleur to take up the sag.
Great video. Did you have a derailleur hanger extension on? I am installing a 11-32 cassette from 11-28 on my Short derailleur ultegra 8000. So do I need the RD hanger extension?
A short cage derailleur will accommodate the 11-32t cassette! All you have to do is fit the cassette and adjust the b-screw and you’re good to go!!
Exactly what I wanted to know...❤
Does that mean you are now selling your 11-32 cassette? Great video by the way!
This is a quality presentation thanks, and superb Channel ... I have a new Canyon Ultimate CF SL 8 fitted with Shimano Ultegra R8000 SS 11-speed, short cage design, which Canyon say has a max. cassette size: 30T. I already have changed it to an 11/32 and works perfectly. I have a 52/36 on the front and want to fit an 11/34 cassette as will be doing a long European tour with big climbs some over 20% . Will I need a longer chain? Is it just a case of putting on the 11/34 and adjusting the B screw?
If you already have a 32t cassette then you maybe able to fit the 34 without the need for a new chain.
@@FreeToCycle Thanks for the super fast reply. Will I be able to fit the 11/34, I can fit the chain as required as you say. I was looking to buy a mid range cage with the 34 cassette … but will I need this?
There's not much point in changing the cage to a gs as the actual derailleur knuckle is slighty different on a medium cage derailluer, if you were going to change the cage you might as well fit a gs derailleur! Or swap the front chainrings to a compact 50/34.
If I am changing brand and speed: from Shimano 105 11-speed 11-30 cassette to a Dura-Ace 9200 12-speed, 11-30 cassette with Dura-ace 9100 11-speed FD and Dura-Ace 50-34T 12-speed crankset...what problem I will encounter? Do I need to change the 11-speed chain?
another great vid! Could you keep the same chain if using a 30t?
30t on my bike,can I jump on 34t? I will buy new chain of course ,Thank you
How about 11-34 cassette to a 52/36 crankset? Is it possible without any issues with shifting? Chaindrop?
Do you know if it will work moving from 32-36?
I am running a Shimano ultegra Di2 R8070. Currently I have a 52/36 in the front and a 11/30 in the back. I am not sure on what cage I have. I read online that a medium cage measures 74mm centre to centre of each jockey wheel of the RD, so I assume i have a medium cage, as I measured 74mm. Would I be able to run a 11/34 in the back by only adjusting the B screw and a longer chain or do I need other changes too?
Hi, may i ask, this video using ultegra r8000, how about dura ace 9070, also same result ??
Great video. Would this work with the same Ultegra derailleur switching from an 11-30 to an 11-34 with 52/36 chainrings? Also would I need a longer chain? Many thanks
Yes it will work! You may have to add a couple of links to the chain and adjust the B screw after fitting the cassette.
@@FreeToCycle Brilliant. Many thanks for the quick reply!
Too bad... I should have seen your video. I have just ordered a new di2 derailleur with medium cage (gs) with the 11-34 cassette in order to mmive from 11-30 to 11-34. Do you think the results are the same with di2 ultegra (8050) rear derailleur than with the mechanical one ?
Do you think my old Ultegra rear derailleur RD6700 can handle 11-34 or 11-32 cassette? :)
Yes
What is your front ring difference? My capacity is 37. I want to use a Shimano GS Medium but the spec says my 16t front difference is to much? "Maximum Chain ring Size Difference: 10T (medium GS version), 22T (long SGS version)"
HI! what chain length do you use? In how it work with BIg+big and smal+smal gear (52+34 and 36+11)
I have a 52/36 on front and 11-28 cassette. I have the 6800-ss. Can I upgrade to 11-32 on the back ? Will my RD handle this ?
How about jumping from a 11/30 to 11/34 is a new chain needed?
Hey buddy... do you know if a 11/34 will work with Shimano ULTEGRA Di2 RD-R8050 11-speed Rear Derailleur SS ?? or you think I'll need the GS???
I run Sram Apex 10 speed with the short cage derailleur (only goes to 28) ...do u think I will be ok to go to a 34 cassette with wolf tooth extender and a new chain ?
Did you try it? I'm planning to do the same, but an 11/32
Could you use this same principal with a 10 speed going from 11-28 to 11-34?
Can I run 11-34 to my r7000 SS RD?
nice info. I am about to change CS-R8000 11-30T with short cage derailleur to a new cassette of CS R8000 11x34 together with a new set of longcage derailleur and a chain. After watching your video, I stopped moving to cassette change. Could you tell me what the difference is there between Ultegra CS-HG 800-11 (11x34) you are talking and CS R-8000 11-34.
There is no difference the cassette’s are both the same!!
Will this work with my old model Ultegra 6700 short cage 10 speed? I'm currently running 11-25 cassette
No!
I added a road link anyway, but works great. The problem I have now is that the chain is really noisy compared to before I changed it. I can't see the chain rubbing on anything. Can you suggest why it's got so loud?
Shouldn’t be any noisier than before! Is the chain routed through the rear derailleur correctly?
@@FreeToCycle yes, everything is the same but I added a road link, new cassette and chain. It sounds like the chain is rubbing on a derailer but I don't see any rubbing
@@FreeToCycle I just checked again and you were right. The chain wasn't aligned in the cage right so it was rubbing. I unscrewed the cage and put it back together again. All working silently now. Thanks 👍.
If I replace the SS cage of my r7000 with a ceramic oversized guide wheels which are 18t-13t wheels, will it be sufficient enough to go upto 40t cassette?
No!
I'm gagging to try this 11-34 on my Dura Ace RD-9000-SS 11 Speed. Will it handle it okay FtC ?
Not on a DA 9000, unless you fit a roadlink!
Thanks another very informative video, I have a 8000 Ultegra rear mech how do I know if it's short, medium or long cage
On the back of the cage between the two jockey wheels it will say either GS for long cage or SS for the short cage version.
Great video, thanks. Will this work with a ss 105 or tiagra rear derailleur?
Not with the 105 5800 or Tiagra 4700!
Is it fine to change the cage from short to medium and long if you start from there and want to go big to fit say 11-46 or even 11-50?? I just purchased for me an upgrade in SRAM Force1 but I think it has short cage and is for road but would love to use it for a little off roading steep hills and such?
Yes you can even install a long mtb derailleur
Very informative! Will this work with my Shimano 105 RD-5701 SS derailleur currently running at 11-30?
You would require the GS version to run a 34t cassette.
Is it possible to fit an oversized pulley on a 11 34 teeth cassette
A little off track...but what is the lightest 11-32 cassette I can purchase for use on my road bike? Using Shimano derailleurs but don't mind using Shimano or SRAM cassettes.
I would stick with the Ultegra R8000 11-32 or if weight is the goal then you would have to go to the Dura-Ace r9100 11-30 cassette. czcams.com/video/Zd_MMccIkFw/video.html
Hi, when you fit the 11 speed 34 from a 32 cassette do you need to fit any spacers etc or will it just fit without any adjustment other than the B screw
Thanks
Straight swap other than the B screw!
Thanks for this video. I've been running the same 11-34 cassette with the 34/50 chainset and the Medium cage Ultegra rear derailleur for the past 12+ months. In general, I really like it and it suits the hilly terrain down here in Cornwall. However, I do find some of the jumps between the 11-19 cogs whilst in the big ring to be quite noticeable - I sometimes struggle to find the right gear during group rides. I wonder if the 11-32 would suit me better?
PS: I only bought the Medium cage (SGS?) R8000 rear derailleur, because I ran an 11-40 cassette during last year's Etape du Tour (with a Wolf Tooth Roadlink).
When using my 11-34 cassette I have to frequently shift chainrings to get the proper ratio. This is annoying. So, unless I really need the 34 teeth, I prefer to use my 11-32 cassette.
Ultegra only has two Deraiileurs... Short (SS) and Medium (GS), there is not Long... Only for the Mountain Bikes... It's easy to tell the SS and GS apart.. the SS is really short and stubby.
@@Tchairdjian This derailleur in the video looks like a medium. Doesn't look like a short, or are my eyes playing tricks?
@@shitfer That is a SS. I owned the same and and it's longer compare to say a Tiagra SS.
Great video. Thinking of changing from 30t to either 32 or 34 t. Chainrings 50:34. Will new chain need to be longer? If yes how many links? Thanks
If going to a 32t you will be fine with the existing chain! You may have to add a link for the 34t, but try it first might be ok.
Thanks for the very speedy reply. I’ll give it a go! 👍
Can i use a 30 tooth on Shimano 6600 rear derailleur?
Would this work with dura ace 9170 with 53/39 in the front?
Think I could run an 11-36 on the 5700A Medium Cage?
What if you had a 52/36 on the front?
Thanks for sharing. Planning to use Tiagra 4700 short cage on 11-32T cogs with 50T chainring. Do you think this will work?
Max 30t with a Tiagra short cage derailleur! You would require the GS version or a wolf tooth road link on the SS to run a 32t cassette!
Is this applicable with 105 r7000 short cage? 🙂🙂
Sir.. This method did it work with 105 R7000 ss rd??
Is it ok to run big ring (53/50) and 34t cassette at the same time using short cage?
Thanks for the great video! I've been thinking about this for a while now, I've got an 11-28 with a short cage 105 derailleur (RD-5800-SS) and I want to swap the cassette for an 11-32. Do you think it will also work on this derailleur model? (Shimano says it can support only up to 28T, but as your video shows perfectly, they are quite conservative in this recommendations)
Not with the 5800 SS rear derailleur! It will work fine with the R7000 short cage rear derailleur.
@@FreeToCycle Thanks for answering! Too bad it wont work with the 5800 series... but these are an older version, so I had guessed they would be a bit more limited. Since I have to get a new one anyway, I might as well get the R7000 middle cage, I don't mind the couple of extra grams, and at least I will be inside the specifications.
Will this work for ultegra 6800 short reach rd? It is like same design at 5800. Hope someone can answer my question?
No not with a 6800 short cage derailleur!
RD-7000-ss can support for 11-34T on 22 inch folding bike?
Hey! Very informative! Will this work with my Shimano Sora RD-R3000-SS?? Thanks!
Not with the SS rear derailleur unless you use a derailleur hanger extender (wolf tooth road link) or a GS derailleur!!
It looks like that derailleur is fitted with a wolf tooth or similar....
Nice video! I have 2 questions: 1. This video used an Ultegra R8000, but I have a 105 R5800. Will I get the same results? 2. The cadence change on the 15-13-11 cogs is large. Could 14 and 13 cogs replace the 13 and 11, maybe with Shimano or Miche sprockets?
To run a 11-34 cassette with a 5800 rear derailleur you would need to fit the GS version!
Thanks for the quick response!
Just did this upgrade on my SL7 and everything seems to be working. I can shift all the gears except when in the 34 the rear mech grinds from touching the cog. I didn’t extend the chain and the stock cassette was a 11-30. My LBS is closed til Tuesday and I adjusted the B screw until it will go into the 34 cog and still grinds. All other shifts seem to be fine. I cant seem to get any more room out of the rear settings. Do you think this is because i need a longer chain and provide more slack? Thanks for the video also, saved me some money.
What derailleur are you using?
It’s an Di2 ultegra
medium cage
The gs version is designed to work with an 11-34 cassette as standard! So should have plenty of adjustment on the b-screw! You could try adding a couple of links to the chain.
@@FreeToCycle just picked up a new chain, will swap it in the morning
will that new existing chain lenght work if all of a sudden I use a wheel with 11-23 ? or backnto 11-28 ? whats your crankset sizes ?
You would need to resize the chain to go from a 11-23 to a 11-28 cassette!
@@FreeToCycle Went from a 52-36 to a 50-34; The cassette remained the same 11-28. I did not change the chain length. Everything shifts fine. If I switch to an 11-30 or 11-32 or 11-34, would I need to increase the chain length? Thanks! (r8050 di2 ss)
hi will it works for my RD 9070, plan to upgrade from 28 to 34 cassette
Not with a Di2 short cage!
Does this work with 36-46 in front? I have ultegra 6800 SS with 11-28, could use the 11-34 for the hills.

No you should be fine! As long as the chain has been sized properly in the first place.

Hello,
I will update my rear cassette from 11-34 to 11-30, my rear derailleur is a long cage GS it will be OK using a long cage GS with 11-30 cassette?
According to Shimano website short cage is OK for 11-30 cassette but i need to use the same derailleur so it will be ok with my GS long cage derailleur?
The GS derailleur will work fine with a 11-30 cassette!
@@FreeToCycle thank you for reply 🙏🏻🚴💨♥️
Hi
Would a dura ace rear derailleur take the 11 34 cassette?
If its the same length of the ultegra, probably
Hi, what about running it on 50t ring and 34t cog, is it possible? Thanks.
Then you take off the 34t chainring.. Note : you 50t chainring is intended mainly to speed up more on a straight descent or flats. The same goes for the 34t chainring is intended for largest cog to have a easier climb on steep roads.... Again 50t chainring is for speeding up and 34t chainring is for climbing up.
How many links do you add bro?
Can you fit a 105 set on a specilized allez 8 speed .
Yes if you upgrade the entire group set to 105 and get a new wheel set. Your 8 speed freehub won’t fit an 11 speed cassette.
I need some help im not sure wether my RD is SS or GS. Any idea in how i can identify it? Thank you 🙏
The derailleur has it stamped on the outside of the cage nearest the spokes!

Looking to make this change on a couple of bikes, wondered if you could help before i spend out.
Bike 1 - 36/52 chainset, 11-28 cassette with a 105 5800 rear derailleur.
Bike 2 - 34/50 chainset, 11-28 cassette with ultegra 6800 rear derailleur.

Thank you
Will this work on 11 34 and 53 39 crankset? Is it safe
Hi Anthony, Any luck with your question? I have the same question.
You say you have plenty of b screw leftover. Does this mean you could easily run a 40t or 42t cassette?
Not on a short cage derailleur!
@@FreeToCycle does this mean 34 is the absolute limit on a ss with hanger extension or do you think you could pull off 36, 37, 38?
You will need a Roadlink to go larger on the short cage!
@@FreeToCycle so with an extended wolftooth road link how big of a cassette could you push a short cage
Need your advise, I want a better climbing roadbike, I ride entry level Giant Contend 1, Sora groupset, 32/9 cassette w/ 50/34 cranks. Is it possible to upgrade for easy climbing without costing to much? Thanks from USA.
Options are limited for upgrading the Sora groupset any further! If you want lower gearing then I would suggest an upgrade to 105 r7000 11 speed with a 11-40 mtb cassette on the rear that will give you all the range you will ever need!!
@@FreeToCycle OK thanks.
You can just swap your rear derailleur for something like Altus ALIVIO or DEORE 9s and get something like a 11-40 or 11-42, sora is the last road groupset that is compatible with MTB
@@din3832 Thanks will look into it.
The problem with a 9 speed with a 11-40 cassette is the ratios are to wide between each gear! Especially for road riding.
Works with 11-36?
