okay so I’m having similar problems with my octalink setup. I did a deep cleaning of my bike earlier this summer and took out the BB for giggles. probably dumb, I know, but I cleaned it and regreased. Now the dumb thing creaks and pops all day long no matter how tight I tighten the crankarm bolts.
did I screw something up? I’m considering putting some locktite on the inside threads of the bb shell.
oh, related, are the splines on an octalink all the same size? Or is there one that is bigger or smaller for orientation?
