19mm spline sprockets
22mm spline drive Galaxy sprockets
Profile Racing Galaxy 22mm spline drive sprocket, Made in USA of course.
-CNC machined from 7075 Aluminum in the USA!
-Requires no sprocket bolt. Instead, it has a hardened CrMo steel insert that matches up to the 48 splines on the crank axle for pure, direct power transfer. Spline drive helps eliminates that annoying "up and down" in your chain.
-Available for 22mm splined axles only.
-1/8″ tooth width for use with all freestyle/street & single speed chains.
Supplied with 22mm 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.
