PERFECT
- JULIO, 23 December, 2023
Excellent bottom bracket. I have the same one on my Colnago with a lot of miles on it and it is still "PERFECT". I'm going to mount the new one on a friend's Italian frame. The only drawback is that you need a special spanner (or a generic spanner) to fit it and it would be nice if the tightening torque was marked on the cups, so you don't have to look it up on Shimano's web site.
