Good , bad, indifferent, right or wrong. The whole facing thing gets me, this is my reasoning…if the original bb in the frame of my mass produced f/s bike lasted ( in my view) an acceptable length of time , in my case almost two years ,despite the bike perhaps not being ridden as often as it is now and was still used in the ,horrid ,winter ,,muddy conditions we have locally, bearing in mind also , that it was a lowly Shimano jobbie, had the frame not been produced to adequate tolerances in the first place, wouldn’t it have worn out months previously ?
No bb issues I’ve had since could ever be put down to not having the frame faced.
I’ll agree to differ in the face of reasonable argument though, but it will need to be a good one.
