Niner Biocentric is the asymmetric bottom bracket adapter for a single speed.
Below is the II. I have the I. I could not find a picture of the I.
It is stuck. I have tried penetrating oil for days. On side (drive) moves a little and the other no movement.
Any ideas on how to get it to free up?
Big hammer is not an option.
It used to move OK but it was squeaking a bit so I torqed it to spec and it froze up.
I am thinking about taking it apart but right now I cannot get my Raceface Evolve crank off.
