Thinking of doing an Ultegra build of the 2020 R3.
Any feedback from riders out there ? I’m currently riding a 2018 R3 and find the frame stiff yet comfortable. However, I’m debating on making the switch to disc for next season !
This will be used primarily for road/crit racing.
Thanks!
I doubt you’ll notice much difference outside of usual rim vs disc stuff!
I love Cervelo R series. The only complaint with my previous gen R5 was the horrible rotor BB it came with. I yanked it out and replaced with a Hambini BBright one. From there it was smooth sailing.
Should be a great purchase! What color are you going for?
Probably black. My current R3 is bright yellow and everything shows 
Hambini BB eh? Interesting, I’ve seen his videos and the man definitely knows his stuff. Does it come in 24mm for GXP cranks ? I have a DZero Quarq that I’d like to keep using.
Ah! Not sure if he makes them for gxp cranks as he’s not a fan of the gxp design.
WMFG has got you covered though. https://wheelsmfg.com/bottom-brackets/bbright.html?crank_spindle_dia=7120
Cbear is another brand people swear by. I have no personal experience.
Check out the hambini Cervelo bottom bracket rant video first, his stuff is made to tighter tolerances than Cervelo use so may not fit!
I have a R3 disc with Chorus components and with the C-bear BB. I have not had any issues with the BB, it has been smooth and silent since the beginning.
I have not actually yet installed the C-bear bearings, still using only the cups with the original Campagnolo bearings that came preinstalled with the crank. Both are of very high quality, there should be no difference.
Thanks,
I’ve seen the video and it is definitely concerning. But I’ve got a very good relationship with the Cervelo shop so I’m confident any issues would be taken care of.
Cool, didn’t know about c-bear. I’m running the WMFG right now in my current R3 … Will probably just swap it out if I stick with GXP.
To me it was more concerning about hambini, put me off his products!!
