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.
Flat Society has a unique selection of parts when you’re building your dream bike. Fast and friendly customer service too. This sprocket, along with the 19mm Profile Race cranks, is going into the best drivetrain I’ve ever had in a bike. Can’t wait to rip it!
