Building up this frame for a friend - https://www.racycles.com/product/detail/10193
It has a BBright bottom bracket, and the secondhand frame came with new Rotor 4630 bearings installed, but nothing else for the bb.
So assuming I install a Rotor 4630 bb, what single ring crankset will work with this. 30mm axle, but does it need to be be BBright specific? And gather the bb shell is 79mm (altho when I measure it, it looks more like 83mm?).
Any guidance would be great - for context, he's wanting it to be a light XC race bike, and is fitting XT brakes/shifters/mech.
Thanks
I built up a brand new Cervelo Caledonia road frameset last Summer with a GRX 810 1 x groupset. On that I'm running a Wheels MFG BBright 24mm axle BB so the Shimano GRX 810 chainset (Shimano 24mm axle) fits, I chose Wheels MFG because their design acts like a thread together bb (they get top reviews).
If your mate wants to run a Rotor bb for a Shimano XT crankset then you'd need a Rotor Pressfit 4624 BBright BB instead, should be around £45.
If you're sticking with the pre-installed Rotor BBright 4630 bb then a 30mm axle crankset such as Easton EA90SL Cinch, or Race Face Atlas Cinch cranks should fit.
Thanks, v helpful. He's a RaceFace Turbine 30mm spare so hopefully this will marry up OK
