I've just removed the external BB from my Allez sport. The chainset is Sora. The cranks had started clunking so I thought I'd take a look.
The bearings feel quite rough, so before I replace it, I'd like to know if higher spec shimano external BB's are compatible, and if they're actually worth bothering with!
I know the one on mine is also listed for use with Tiagra, but how far up the scale do these go?
cheers
