Shimming should only be required if your BB width is less then the 67.2 spec....did you measure your BB shell. You should not use shims in place of the wavy washer...the wavy washer is always necessary to provide the constant preload on the bearings and take up any slack/play. Also, not clear from your last post whether the shim you already installed is 0.5 mm? If yes, that seems much too thick...if you frame requires more then 0.2 or 0.3mm of shims then I would definitely call Cervelo and let them know the BB shell width on your frame is too much out of spec. Sounds like you are in a hurry to ride your new frame (don't blame you, I would be too) but do be sure you let the compound fully set or at least 24 hours before riding. Good luck, EM3
EM3, thanx for posting.
The FSA shim is 0,8mm thick! It is plastic, so maybe it gets flat when it is compressed by cranks. But even if wave washer and FSA shim is aplied there must be some play.....because the right cup came out of the frame (0,5mm was just a qeuss).
If it was a tight fit, the cranks would not let cup go out.
Well, I know You have R5....so, You could know that Cervelo BB is not 68mm wide but 79mm
Remember, Cervelo engineered another SUPER TROOPER USELESS BB SYSTEM!
Whatever, think about it with me.....if Campagnolo says, that frame cranks can accept BB width from 67,2 up 68,8mm ...... it is 1,6mm tolerance! It is a huge number!
Wave washer is 0,7mm. So, if I aplied FSA 0,8 + 0,7 = 1,5mm. Still 0,1mm left to the Campa tolerance.
