Product Description
The SunRace MFE909 is a durable 9-speed threaded freewheel designed for dependable shifting and high-torque use, including compatible electric bikes, commuter bikes, hybrids, and recreational bicycles.
Built to tighter tolerances for improved concentricity at the higher speeds and loads commonly seen on e-bikes, this freewheel is a practical replacement for compatible threaded rear hubs. Its 13-32T range provides useful gearing for everyday riding while maintaining smooth operation with compatible Shimano- and SRAM-style 9-speed drivetrains.
This is a thread-on freewheel, not a cassette.
