Bottom Bracket Octalink

In a multi-tooth inner bearing, the crankshaft is part of the bearing, the end of the shaft has several "teeth" that make efficient contact with the crank and can be driven with a lot of torque. The most popular multi-tooth systems are Octalink, ISIS and Powerspline. We have these bottom brackets for you in the store, but you can also find other, rarer copies here.
