the old design was indeed square taper, and i think this one is octolink. I haven't seen any kind of washer when i removed the BB, that might be part of the problem. If i buy a washer and re-tighten it myself, where do i put the washer? between the bike and the BB?
I don't have the original brand of the stuff in my bike, the bb was replaced once, the left crank, 4-5 times. I'm currently checking to see what the brand is for what i have right now. but honestly, if it comes back again, i'll just repolace the whole BB/crank combo with whatever you guys recommend. I don't mind paying for the tools and the poarts if it solves my problem. If i can get away with just a slight tightening every year it wouldnt be that bad, but right now it's a lose the bolt/crank every few months situation, which is unacceptable.
If anyone knows reliable shops in longueuil, canada, i'd be happy to go there. Otherwise, does anyone have a good online store for both the parts, and the torque measuring ratchet?
