Freewheel

A good freewheel is the heart of every singlespeed bike. It delivers a smooth, reliable ride, transferring power directly and efficiently from the pedals. High-quality freewheels use better bearings, stronger springs, and more precise machining—something you notice both in their durability and in how they feel when you ride. Cheaper alternatives may work well at first, but wear out faster.
