-Requires no sprocket bolt. Instead, it has a hardened CrMo steel insert in that matches up to the 48 splines on the crank axle for pure, direct power transfer.

-Available for 19mm splined axles only.

-1/8″ tooth width for use with most freestyle/street & single speed chains.

-Supplied with 19mm splined steel insert.

NOTE: Spline drive sprockets are not compatible with 2-piece cranks for Right Side Drive (not enough room for splines). Spline drive sprockets are compatible on Left Side Drive 2-piece cranks though.
