Hey guys, having grown tired of regreasing my old loose bearing bottom bracket I decided to fit a sealed unit one... only to find it seems not to work. The fixed cup (driveside) threads in fine, but if you look into the shell from the non-driveside before installing the other cup, you can see that the axle is not in the centre of the shell. As such, the remaining space around the bottom bracket where the second cup should go is uneven, being much narrower on one side. This ends with me being unable to install the second cup. Any idea how to resolve this? I've heard the bb shell could be faced, but I am not really sure what this entails? Cheers!
