- In this video, I go over how brake rotor size effects performance, the difference between 1-piece & 2-piece rotors & Hope floating rotors, and an in depth comparison between centerlock and 6-bolt (IS2000) rotors.
The rotors that I run!
Centerlocks:
203mm Shimano Freeza Front www.amazon.com/gp/product/B00...

Great point about the rotor rocking and where to set it. I made that mistake so this is very useful info! Thanks.
Great infotainment! Just swapped my discs today, so this came in handy! Love your channel, keep up the good work!
Another useful video. Learned something new about "clocking" the rotors. Keep the good vids coming!
Re: 6 bolt... Quality tools make a difference.
Yeah, if you manage to strip a torx bolt, you are either using the wrong tools, or too small a torx wrench...
Also: Torx or hex bolts can easily be torqued correctly with a standard torque wrench and the correct bit, this is a lot harder for centerlock.
Super great video: just what I needed. The new MAVIC tubeless wheel/tyre system here I come. Thanks.
The combined weight of my large frame Bosch mid-drive bike and commute items are 300lbs. I am currently running a 180 front/ 160 rear. I live in super-hilly San Franciso. I am going to 203mm.
Thanks for the most excellent and professional presentation.
Hello Alex! Big and warm THANK to you for this very good and excellent information and the hacks and the instructions too that help me out when I am about to upgrade my disc rotor and brakes that needs to be considered by my new wheels set from DT Swiss Carbon XRC 1250 wheelset with the center lock/adapters for 6-hole rotors as well. Your information was spot on for my need right now so you made my a great favour by posting this also interesting and well done YT Video! Wishing you safe and happy riding always! Best Regards, Charl (Sweden)
Just found your channel, and I need to learn more about my bike to get the most out of it. Subbed!
Wow. That gave all the info I was wondering about, and a lot more that was super useful.
Really helpful and informative video...If you do another live stream I would focus on just a few items and limit questions to those...I have yet to see anyone control many people and many different questions. With your MTB videos the two together will increase your viewership! Good luck and I'll keep watching!
Thank you! The video explained my questions about rotors.
A big reason to get centerlock is that i remove the rotors when
1) i wash the bike
2) i lubricate the bike
3) i give inspection o maintenance to the hubs
Great vid, I learned a lot..thanks Alex.
Great video! I love my centerlocks and I use an adaptor to run 203mm Sram Centerlines on my Firebird.
Very cool, thank you for all the information! Enjoy your rides man!
Great vid. I learnt a lot. Thanks.👍🏼
Great video! I am just building a bike for trekking and don't know what tipe of brake choose, thank you for this information!
You also have more brake power due to the increase in leverage on the wheel, that's the main reason to use big rotors on DH or Enduro application.
Exactly. That's why bigger rotors bite better.
Thank you! So many fail to understand its a direct mathematical relationship. 10% bigger rotor means 10% more braking force
@@SeaCowsBeatLobsters That is because the leverage increases with the radius. So if you want the maximum braking power go for a four piston caliper (like the BR-MT520) combined with a 203 or even a 220 mm rotor. And if you want to push it even further, go for the Magura four piston caliper, this combo is called a Shigura.
The secret of a Shigura combo is the bigger amount of fluid being pumped by the Shimano lever compared to the original Magura lever AND the bigger diameter of the Magura caliper pistons compared to the Shimano caliper pistons.
Nothing currently on the market beats the bite of a Shigura!
@@ralfrufus6573 Also Hope has a 225mm rotor
this guy (in the vid) really doesn’t know what he’s talking about. he says that there is a safety issue with center lock 😂
Great video, FYI bolts rely on clamping force to keep the joint together hence the clocking is irrelevant. It is very common for bolted connections to have clearance holes around them. Also never heard anyone say 'Not a fan a torque wrench because they are sloppy'. Most people over tighten bolts by hand !
Excellent video. Thanks for all the detail and info.
Great vid, all questions answered and more! Oh, and cheers😀
Really helpful and informative video.
Good stuff, great edit.
super informative. great video dude
That's super cool dude, it's nice to see someone in my realm making CZcams videos, I never make them because everyone seems like a, "pro broadcaster" type. Additionally, before this video, I would have been like, "NAH 6 BOLT"; but you really made some valid points! Good video!
Great job bro & thanks!
Great video Alex! Thank you very much!!
Great info, thanks! I ride 180mm Shimano XT front and rear but am looking to upgrade to the saints. As I'm progressing I now notice a lot of fade from the XT's especially on steep stuff... was looking at the SRAM guides until your rant during the bike build live stream
sram can definitely work for some people! I haven't had the best experience with them in the past. I'm also a heavier guy and tend to ride steep trails. I am biased but idk. I could be a little nicer to other brands😅
In the bike shop I used 2 work at, we took the centerlock rotors with the freeza discs and removed the Centerlock stuff and then milled in a kind of notch to flatten everything for using 6 bolt hubs and then drilled in the holes of the bolts. Works pretty decent in deed
Leo Löff sketch 😂😂😂😂
I can send U a pic the next time I am in the shop, but it's basically quite simple. You just need to mill out enough material that the rotor doesn't hit your fork, but can still handle the 6 bolts needed for the assembly and then you need to carefully drill in the holes. Okay it's quite alot of work, because the drills have to be in the same line and must be equally far away fro the center so that the rotor isnot out of round radially. We do this on expensive custom builds (Liteville, Cannondale, Nicolai, Santana etc...)
Hey man just got on to your videos, they are great!
I see this channel going places like with "Seths Bike Hacks" I was one of the early subs and watched it grow
Keep doing what you are doing mate, develop your own style and I wish you great success
Thanks Lucas! I'm definitely trying to find my own style and to mix it up. It's so awesome to hear feedback like this and to know the channel is on the right track. Cheers brother 🍻
hey man, hopping onto this "style" topic here. I reckon you have a good setup going here, when you look at all the other MTB youtube boys, they're all pretty big jamokes when it comes to pro mechanic stuff, i mean seth rides a diamonback FFS.
There are a lot of us mechanic nerds/aspiring racers that love this nitty gritty detail oriented tech stuff, so keep that coming. You're a good rider and all, but don't get too bogged down in the gimbal POV stuff, there's already like 12 channels doing that. Keep the pro tech and pro racer stuff coming, you're really the only one doing that at the moment.
That's exactly right, I'm a huge nerd when it come to bike tech, would love to see more content like that, as well as vlogs of your races or mechanical stuff you do
Alex Rosenberry If you were such a "mechanic" you wouldn't care so much about brand.
what? Why not? Most mechanic/tech nerd guys are more opinionated about brand than anyone else.
You're not any less of a mountain biker for riding a DB, but there's a reason you don't see tech nerd guys and aspiring racers and privateers out there riding diamonbacks even when they're often the cheapest option
Hey man great videos! I have a question. I have a 2019 Yeti SB6 Turq with we are one wheels and I9 6 bolt hubs. My rotor sits close to the frame (caliper mount). Like so close its scary. In your opinion what is to close? Also would a rotor sit closer or farther using a 6 bolt compared to a center lock?? Thanks!
Hey I have a Scott genius 750 which takes 27.5 and 29 wheel sets. It came with a 27.5 set with center lock brake rotors (shimano) and I got a second 29 set separate with 6 bolt rotors (Clarks) . Hubs are boost. I put the new wheels together and on bike but new rotors seem to sit very differently in the caliper. The front rotor even drags a bit on the assembly. Any ideas what I should do next?
Hey Alex,
I was fitting my DT350 hub to my xtr rotor and when the lock ring is finger tight, there is quite a bit of movement between the hub and rotor. Is this normal and will torquing down the lock ring to 40nm fix this?
Right on thinking about changing to the shimano 180 rotors due to the heat dissipation not being very good with the sram 180
Great video mate thanks 🤙🏼
Hey Alex, I have Sram centerlock rotors and I want to install them on a wheel set with a 12mm axle. Can I fit 15/20mm Shimano HB20 lockring onto them? (The wheels are Roval CLX 64)
Just wondering if you think they will be making a RT 99 Freeza for 6-bolt any time soon? Or an Adapter? Great videos and thanks for the information!
Nice video. Thank you. Is there any problem switching between center lock and 6 bolt wheels. I am using shimano calipers with center lock brakes and thinking of buying a new set of 6 bolt race wheels. Thank you.
Great ! Super useful! What about using shimano rt99 rotors with entry level deore brakes?? Does it help? Maybe adding the ice tec pad to...?
Hi. I have a Caad12 with center locked disc brake rotor. I am getting a good deal on Fulcrum Quattro DB wheel sets but these have 6 Bolt hub. Which adapter should I use to install my center lock rotor on to the 6 Bolt fulcrum quattro DB Wheelset? Or will it be better to change my centre lock rotor to 6 Bolt rotor?
What to consider when upgrading your brakes parts, dimensions, and compatibility.
great video thanks. i'm about to buy a set of wheels with dt swiss 350 centerlock hubs on it. my current MTB bike has 6 bolt hubs on it. will the new wheels with centerlock hubs fit properly on the same bike with the new hubs and rotors? will the disc be in the exact same spot and line up properly? thanks
Hey dude. When you tightened the centerlock you mentioned 40NM but didn't appear to use a torque wrench? I'm travelling abroad with my bike soon and have the EVOC bike bag. I'm concerned that the discs may get warped in transit as they're on the outside of the bag either side so I'm thinking of removing the discs. However I don't really want to buy and take in the bag a huge torque wrench abroad. Is it possible to tighten the centrelock with a tool (such as the one you used) by feel? i.e. pretty hard
Hey Alex,
Great review as always. I am building a new top-grade build bike (Ibis HD4) wehn my frame comes in soon and I was wondering if you have ever ridden the SRAM Guide RSC or Ultimates? I ask as I know that you currently run Saints, and I was thinking of them as I have the extensive moto background and am so use to powerful and precise brakes, and currently been running XTM8000, which stop very good, but I find with no/minimal modulation that the rear tends to lock up on dry steep fast downhill stuff, no matter how much I finesse it.
I just rode a demo bike with Guide RSC's and they felt great with some good modulation, not too much tho, and seemed to stop great, but...I was only able to ride the bike on the street on flat ground.
As of now, now shuttling, but do love demanding DH stuff. So, just wondering your thoughts on Saints vs top SRAM's for demanding Enduro that has steep technical DHstuff, but with some climbing and all around trail use???
I kind of prefer to run the SRAM's if can get away performance-wise because of modulation and a very significant weight savings, but not if too much sacrifice with the riding I described.
Oh, do you have any comparison in modulation of current XTM8000 vs Saints??
I am running Ibis 742 wheels with i9 centerlock hubs so I was also wondering if you running the "Freeza" centerlock rotors, or the non finned Ice-Tech's? And 180mm/180mm, or 180/203?
Thanks buddy!
If my bike came with center-lock hubs / rotors, is it possible to put on a different wheelset that uses 6-bolt? Or is a frame designed to accommodate one or the other?
I bought a replacement wheel for the front of my bike, the original wheel was a 6-bolt but the new one is a centerlock. I am using a adapter for the 6-bolt rotor that I have, so i can use it on the new wheel. I dont have a preference but I noticed that the new centerlock (using the adapter) rocks after I tighten it. Theres play in the teeth. Is that normal?
Thanks for the video, I'm trying to download disc brake knowledge into my brain to catch up with modern technology. Now I'm left with questions about brake compatibility. Like, details, guidelines and "bottom lines" about mixing calipers with rotors. Sizes, size limits, what can be mixed and matched. Not really looking for hack solutions, just want to know which things you can generally slap together and have work. The context for me: I am building my own bike and it might be a Frankenstein depending on what I can find.
I have a specialized roubaix sl4 with tektro 140 rear disc and 160 front disc 6 bolt. I bought a wheelset that is centerlock. Should I use an adapter to use the same 6 bolt rotors or just buy new centerlock rotors? If I do change into centerlock, will I need to change the braking mechanism, or will it not be affected? Thanks and great informative video.
Just bought new rotors and they are 6 bolt but my DTSwiss hubs are centre lock, which adapters do you recommend?
Great vid!
Thank you!
Great vid
rock it clockwise. good tip. thanks.
Great video, thanks.
This is a very good video 👍
Love these tech videos. Can you do one on derailleur setup and dialing in shifting ? Thanks!
Wyatt Poovey yes definitely! I'll add that to the to do list
I just noticed it is a KTM you have. Awesome! Which model? I cannot see good enough.
Are you still preferring the Wolf dropper lever for the Fox Transfer post??
There are so many options to order, confusing. One option I am wondering, is did you get the "light action" version? Seems like would be good...?
Great vid. Esoteric question but can you use a front 160 to 180 Front brake post to post Shimano adaptor on the rear brake (also post mounts)?
The only suggestion I have on the 6 bolt is to constantly check torque and if you have one the keeps backing out to reapply the blue lock tight. I've have had bad luck with the manuf. included bolts (ones with the blue lock tight) backing out even when torqued per instructions.
Eric O you can definitely run that adapter on both front and rear
Can you mix rotor brands and models with other brands of brake calipers? Say run that xtr centerlock rotor with the heat sink with my sram guide rsc?
Some great new info..tnx :)
another thing i never knew until someone told me about 6 bolt rotors is if you lose a bolt you can use one from a bottle cage mount
i have a 160 6bolt, if i change my hub to a centerlock, can it fit my calliper?
How do I tork it down to 40 Nm by hand? (note my hand does not have measuring capability)
Can you use the shimano rotors with SRAM brakes... I'm looking to migrate back to shimano brakes but from cost perspective want to do it overtime and I currently have a need to replace my rear disc, so... should I grab the shimano option?
Callum Masson it should work just fine!
Thanks for this.
Hi.it would be great a video about chainline, non boost frame 12x142 with 1x chainring compatibility
Shimano Rt-99 is the best rotor there is: centerlock, easy to fit, manage heat extremely well, very hard to warp, bling factor and of course it's not expensive online. I use the same for both MTB and road bikes.
Outstanding info.... I agree on all points. I run Magura MT5 4 piston on 203 6 bolts.... want to use adapter on my centerlock 29...better rotor. Yup hate 6 bolts to thread in 😆 it came with deore/slx rotors but seem smaller on the rotor contact size? Weird.
Thank you for a great video. Cheers
FYI get the 20-100nm torque wrench from your local tool store or an online wholesale supplier. much cheaper price points on the range of products compared to branded bike tools. at least in NZ anyway.
for touring what kind of type the best?
hey Alex, love the vids. I have shimano saints with 203F and 180R rotors and metallic pads. I notice that when I put water on the pads I get more bite and stopping power but with more noise. have you experience this before? thanks Also could you please use a tripod on the camera.
Wilson Veloso I have experience that. Idk why it it does make them grabby!
Also, I'm working on buying a decent tripod. I have a broken one that is about 2 feet tall right now. Usually stick it in a bike stand to get it to a decent height. Bike stand was taken up at that moment for a project
I think it's mainly because water fills all the inperfections betwen pad and the rotor thus giving a better surface area
Hi, what is the name of the tool with yellow handle that you use for removing center lock ring? Thank you.
No-one is going to inform you
I'm thinking about 220 from 203 center lock rotor Would you ?just for ease of mind?
Fox vs Rockshox, or maybe like 34 vs 36. Also, an in depth video on difference in volume spacers and how they impact
Jackson Scott that could be cool. But my quick answer is fox 36 only. Not much heavier than the 34 but a lot more mid stroke support than the rockshox
very helpful thanks
im a new biker
whats the weight difference between the center lock and the 6 bolts?
Good video. Thanks.
could you make a video explaining xx Enduro downhill?
What size bottom bracket tool did you use?
Great profesional vid thx
NICE
My wheels came default with hex bolts. So, that's just what I use.
Xtr 203 sintered. Unstoppable. Though am using flo-tar 203 rotors on new enduro build. Xtr pistons/pads. Have used flo-tar on sram xx 203 on my XC. See how they go on my enduro?? 🤔
the ice Tech rotors have an aluminum piece sandwiched in between the steel on the rotors to help with heat soak.
Alex, What's your peddle choice? BMX or clip-in?
"Power because of less heat" is wrong. At least if you translate "Power" to braking power!
The main reason for bigger diameter is the more torque you can transmit onto the wheel with the same given (fixed) clamping power from the caliper!
This is vector calculation.
Heat can be an issue, but not really in bicycle brakes. This is a real issue in Cars, where diameter is the key and size of material (thickness of the disk) and ventilation (heat) is for reducing heat and lifetime
Sorry but heat can be a problem for bicycle brakes. I've seen many people with 'cooked' brakes where the pad surfaces have melted and the rotors have got so hot that the surface is blackened due to high-temperature oxidation. You can actually make the rotors get red-hot in certain circumstances.
I forgot the most obvious thing which is leverage 😂 my bad...
Xesh001 I was reading and thinking that his explanation is coming from a book not actual practice.
Yes. Heating is a big, BIG issue. Try to brake +2000 m down at +60-70 km/h...
good content!
I can honestly say with 27 years experience in the cycle trade that I've never had a problem with misaligned 6 bolt rotors as you mention. If they're torqued correctly and you use thread-lock on the bolts they'll never come loose. Also a 6 bolt rotor shouldn't damage the bolts if they're correctly tightened, as the rotor shouldn't move. When fitting a 6 bolt rotor you should twist the rotor clockwise before tightening to make sure that it is resting against the bolts.
In my experience any rotor that has rivets in it has a reduced life span, compared to a one-piece steel rotor. That means any floating rotor, or anything with a splined fitting. 6 bolt fitting is the best as you can use a one-piece rotor that won't need replacing when the rivets inevitably work loose.
There's no point in spending the extra money on floating rotors for most people as they're only needed for applications where heat build up is common (downhill/enduro for example).
I find it interesting that the fittings of rotors have changed over the years. Hope originally had a 6 bolt fitting for its first generation brake (which you had to buy with the hub) and then swapped to a splined fitting. The Big'un hubs had their own unique 5 bolt format. Now they're back to a 6 bolt fitting. Shimano have gone the other way - from a 6 bolt fitting to splined.
Aside from the crappy torx driver I was shuddering at the lack or a torque wrench. If you're stripping torx you'r probably over tightening them. Thread lock and then torque to spec, which is a lot less than some shade tree's guesstimate.
I find that using a little cordless impact driver prevents any bolt stripping. Its easy to hold perpendicular to the rotor and apply enough down pressure to keep the bit in the bolt head
@@SeaCowsBeatLobsters Are you serious? An impact driver for
@@chocolate_squiggle yah. One with 1/4" hex drive and 12v battery. Ive found it to be comparable to the torque I can apply with a park tool 3-way
the reason you see all the play with the torx head is the poor quality bolt. it has nothing to do with the design of the head. the QC on the torx bolts is pretty bad and what you see is nothing more than trash bolts.
the torx head was designed to limit/stop cam out unlike flat or philips heads which were designed to cam out to prevent over tightening. a T25 torx head has a torque limit range of 140in lbs to 168in lbs. a quality torx bolt will not allow a bit to wiggle around like that.
Yep, quality Torx drivers and fastenings that are made to the correct tolerances are excellent
The most commen thing I see is that people use a torx size too smal (T25 on aT30 bolt), you can do this but it feels like the bolt is worn out
It's the first time I see someone complain about Torx :) , in my opinion, on my KTM motorcycles, they're the only bolts I don't break. Also, if you fasten them, use your tool's longest lever, not the short one. Using the long side on this type of tool will prevent you turning the bolt at a bad angle. Using the longest side, you can position it better at a 90 degree angle. Hex bolts are far worse. One you over-tighten them, using a slightly worn tool, it will turn the head of the bolt useless very fast.
OxBlitzkriegxO this guy is wrong it’s a T27 use the right tool for the right hardware dumb asses
This
Which brand has the 220mm rotor?
Why do you never run any sram products?, I've often run manitou, marzocchi suspension, and went to a vivid r2c in the back of the dh bike and it's running good along with xo1 dh drivetrain.
I have just had a lot of quality issues in the past. Shimano has proven to be much more durable for me
Do you think one day they will make centerlock the common brake rotor? Because it seems like the pros out weigh the cons.
So can you convert your hubs for a direct mount?
Brian Vaughn unfortunately no. Honestly 6-bolts are fine! They have been using them for years! I just prefer centerlocks!
Yeah, that looks like a lot simpler setup so I can see why you prefer it.
But you can convert your centerlock hubs into 6-bolt. Just like Alex said.
I use centerlock,no issues with them.👍
Have found the hope 2 piece discs to be super nice, running a 225mm on the rear which gives some extra bite and helps with 29” wheels and they dont warp when you get heat into them
Why on earth would you need extra bite on the rear? I mean I could understand if you said fade resistance
What if you strip out your Center lock?
Can u run shimano Rotors with Avid brakes?
Kevin G yes!
What's your take on E-Bikes?
Hi Alex. Why when changin rotors people keep the same caliper? Its works no matter is 160, 180 or 200?
It's the same caliper for every rotor size, yes. What you'll need is a different adapter, which is what sets the caliper at the right position for the right rotor size.
It looks something like this, depending on whether your frame/fork uses the IS (international standard) or PM (Post Mount) system: www.jensonusa.com/globalassets/product-images---all-assets/shimano/br308c08.jpg
Kaat Debusscher thanks ...
The extra braking power is from more leverage over the wheel. Less heat is just a plus.
Nice vid! A standard T25 makes sense on the trail but if you find a T25 bit for a socket wrench, it will make it a bit easier to tighten without stripping or overtorquing.
