About time to replace my BB. Due to chainline issues I need to use a flangeless BB (isis 68x108).Only found 1 BB that fits thr bill so far FSA PLATINUM PRO TRACK MEGAQUAD. Has no flange. Allows me to adjust chainline. Crank is a 3x8 RF north shore with a bash guard.
I would like to switch to an external bearing BB for the strength and longevity, But, then I lose the adjustability.
Any experience with these in particular? Or others in this size (without the flange is the key)
TIA, Tom
