to face or not to face my bb??
I have a surly cc and am about to put on some ultegra 6600 compact cranks(cup and bearing style). I heard that I should face my bottom bracket before I put on this type of crank. Do I really need to do this or is it only important for older frames?
I believe it's only unnecessary for cartridge-style bottom brackets, where the spindle is fixed relative to the cups, though it is still a good idea. It is necessary for older cup-and-cone and newer external BBs. Having the cups and spindle not perfectly perpendicular can lead to premature bearing wear and failure.

My Cross Check came with a fair bit of paint overspray on the bb shell faces and even a bit in the threads so having the shop face the shell and chase the threads is a good idea for any bottom bracket that's alignment sensitive, particularly an external cup type.
I just cleaned the paint off of mine with a little acetone and had no other problems since I installed a Shimano square taper cartridge.
