Sprocket Fixed Gear BASIC 18T

A fixed-gear sprocket is the rear sprocket on a bicycle that is directly attached to the rear hub, meaning the pedals are always engaged with the wheel, and the bike can't coast. In a fixed-gear setup, you can't stop pedaling, and the bike stops when you do. 

It has a 1/8" pitch and a weight of 220g. Available in 18 teeth configuration, this sprocket allows you to adjust the drive ratio to your preference.
