Happy Holidays!
Hard to tell from the pics but it looks more like wear from a poorly fitted BB.
I used the bottom bracket that came with the frame.
Hard to tell from the pics but it looks more like wear from a poorly fitted BB. Not saying that is your fault, could easily be from a BB shell that is out of tolerance.
Now I've found that since the BB hole is not round the bearing race gets distorted and causes the bearings to drag and fail prematurely. I've decided to attempt a repair with carbon fiber and epoxy and an adjustable hand reamer. The blades on the reamer are 105mm long so I should be able to ream both sides at once and keep things lined up. The BB92 shell has to be 40.98mm to accommodate the 41mm BB.
Whats is the name of that tool?
