Sunlite Freewheel

Yes, this unit is designed to be compatible with standard 8-speed SIS (Shimano Index System) indexing. It will work seamlessly with most indexed shifters and derailleurs designed for that speed range.

This freewheel features a 13-28T gear range. The 13-tooth small cog provides a solid gear for flat-ground speed, while the 28-tooth large cog offers enough range to help you tackle moderate climbs.

Freewheels and cassettes are not interchangeable. A freewheel threads directly onto the hub, while a cassette slides onto a freehub body and is secured by a lockring. You should check your current wheel setup; if your existing cluster threads on, this is the correct replacement.

This freewheel uses standard English threading (1.37 x 24 TPI), which is the industry standard for the vast majority of threaded bicycle hubs. It should thread onto most standard freewheel-compatible hubs without issue.

Yes, you will need a standard freewheel removal tool to install or remove this component. Because the tool engages with the splines on the freewheel, it allows you to tighten it securely onto the hub threads.
