Hello all:
So I am building up a trainer bike with extra parts and the left non-drive side crank (Ultegra 6500) will not stay tight on the Octalink BB. Seems to be but after a few revolutions the crank starts to loosen and wobble. No issues with the drive side. After some research, the consensus SEEMS to be that the internal "grabbers" on the crank arm can get damaged pretty easily? Just wondering if there is any option other than a new crank arm, or any insight that I may not be aware of.
(But if anyone has an Ultegra 6500 left non-drive size crank arm, 175 length, let me know!)
Thanks in advance for the knowledge...
Dan
