Direct mount rear brakes for 28mm rims
Moderator: robbosmans
The last piece of the puzzle for my new chinese bike build are some dm rear brakes for my 28mm carbon rims. I can't seem to find any that fits.
I have tried the new sram s900, but no dice.
I have also tried Ultegra R8010-RS Direct with the thin shimano brake pads for carbon rims, but still not enough clearance.
Do the dura ace r9010 have more clearance than ultegras? according to the manual both should clear 28mm rims with the thin brake pads, but i'm not sure since the ultegras certaintly didn't.

i was pretty bummed by this exact situation on my felt AR. I "solved it" by removing the conical washer behind the pad holder. It's not perfect but gets you an extra 1.5-2mm of clearance

That seems weird. I have Easton Aero 55 (these were probably among the fattest when they came out) and the 2015-2016 EE brakes, not direct mount, but i have lots of clearance so i could probably use 30mm rims without issues.

I'm pretty sure the eebrakes will solve my problem, but they will, unfortunately, create a new problem, a financial one.wheelsONfire wrote: ↑Thu Aug 09, 2018 12:25 pmThat seems weird.

if you only need a few hairs of clearance, EE brakeshoes might do it. They have lower stack than Shimano or SwissStop shoes
I've got some Farsport rims that are very wide. 29mm I think. I just got a set of Tririg Omega X brakes and they work great. Plenty of clearance with 25mm Conti GP4000s's measuring out at 30mm. No more shaved pads for me. Mine are regular mount but it is also direct mountable.

Hi
Tririg worked on my 2018 AR 1 also.
The bottom mounts suck with dirt accumulation after a rain ride.
A TRP 860 have a lot of room but never used one yet.

yeah. the very reason why my rear eeCycle rear DM brake failed.
I noticed some brake rub and looked and found the centering device tab broke off...rendering the brake to skew to one side. not sure how the warranty is on them, now that Cane Creek bought them out.
The entire assembly was so mucked up because of all the dirt and grime.

A bit of a thread dig but I am look for more precise info re direct mount brakes.
It appears as though TriRig Omega X is about as good as it gets for clearance. Is the stopping power on a par with Shimano?
Also the focus of this thread is rim width but what about tires. Can the Omega X handle 32mm measured?
Found an Omega thread which shows a lack of consensus on stopping power: viewtopic.php?t=147470
Any other suggestions for 28mm rims and 32mm (actual) tires?

Pros ride normal 9100 calipers with 28mm Shimano rims all the time. Width usually isn't an issue with DM calipers, fork clearance with the pads (thus limiting how wide it can open) and height clearance are usually the limiting factors. EE brakes offer even more clearance than Shimano and their brake shoes also offer slightly more clearance than standard ones. Never tried but I'm confident they would clear at least a 30.. not sure about a 32Mr.Gib wrote: ↑Sun Jul 19, 2020 10:35 pmA bit of a thread dig but I am look for more precise info re direct mount brakes.

Thanks, rim width accomodation is well known and yes it seems 28mm wide rims can be made to work well with most DM brakes. Assuming you have a DM rim brake frame designed to max out tire clearance, that leaves the issue of what size tires the brakes will clear. I suspect 32mm tires will work with some. Would be nice to know which. Bontrager Speed Stop Pro is interesting. Groupset will be Campy record.
FWIW I have a 10 year old frame that handles 32mm with Ultegra 6700 calipers, so I don't think I am asking for too much.
EE is out of the question. A moral objection to that much money for brakes.
And I already have a nice disc bike so that's not my problem.

Anyone else have the same experience with the R8010-RS? Believe I've read the opposite elsewhere on the web.epoklar wrote: ↑Thu Aug 09, 2018 10:57 amThe last piece of the puzzle for my new chinese bike build are some dm rear brakes for my 28mm carbon rims. I can't seem to find any that fits.
