Octalink crank
Hey all, I made a dumb decision and bought a new crankset for my bike without realizing it was octalink. I'm not very familiar with octalink so what are the benefits of it? I might get an octa BB if it sounds better than having a square tapered set-up. Or maybe I should just sell the crankset?

I bought an octalink BB once by mistake and promptly returned it.

There's nothing wrong with Octalink. That's why everyone else copied it (not quite identical and called ISIS). The BB cartridges are easy to install, need no adjustment, are maintenance free, and cheap. I'd choose one over square taper.

Whether you bought the right crank for your bike is a completely different issue, though. And for that question we'll need lots more info.

From what I understand Octalink v1 has been more or less abandoned for Octalink v2. The difference is the depth of the splines on the crank arm interface. Octalink v2 is very nice and easy to install. I just installed an Ultegra 6603 crank set replacing a Bontrager Select ISIS drive and have noticed an increase in rigidity.

Check out the mechanics forum for other details concerning Octalink.

I'd take square-taper with loose balls any day over Octalink. Or external-bearing cartridges for that matter. Perhaps the top-end Octalink, or ISIS, is alright. But the medium - lower ones remind me of an ice-cream churn. That's my honest opinion.

If I were you. nd bought a crank, I would buy the bottom bracket to go with it, since the crank is usually the expensive part of the package.
