I just put together a new mountianbike. I installed my Hollowtech II crankset and took it for a spin and realized this new frame had a 68mm BB instead of 73 like my old one. I put the correct number of 2.5mm spacers in 2 on the drive 1 on the non drive and reinstalled the crank. It was significantly harder to slide the axel through the bearings and now the crank feels like it has a alot of drag. Don't see how the spacers could cause that?
I'm taking the bike on a camping trip tommorow and wondering what to do. Would I really notice some drag at the bottom bracket? I have a cartridge crank I could install.
There's a bike shop on the way I think I could stop by there and get the BB faced, but they may not be open.
Thanks for any advise.
