I recently broke the threaded insert of the carbon cranks that came on my bike (I bought it used, I would never have gotten carbon myself). Luckily, it's the left one, so if I can get just an arm, it'll work until I get a new crank set.

The problem is, the spline is ISIS, and the length is 170 mm. Several local bike shops don't have them, and I couldn't find one on google. Anyone know where I can find a left ISIS 170mm crank arm?
