Premium 22mm 2pc Cranks
You Save 49% (
The Premium 2-piece cranks use the same seamless heat-treated 4130 Cr-Mo arms as the 1948 cranks, but feature a 22mm 48-spline spindle. The 2-pc design simplifies the crank by permanently fixing the right arm to the spindle. Eliminating the need for a bolt on the right side of the crank set. The large 22mm spindel increases stiffness while reducing weight.
