EXCESS EFW-S FREEWHEEL

Product Overview

The Excess EFW-S Freewheel is a BMX racing freewheel designed for standard threaded hubs. It provides reliable coasting function for single-speed racing applications.

Key Features

• Threaded freewheel design – Screws directly onto threaded freewheel hubs; traditional freewheel mechanism allows coasting when not pedaling
• Single-speed compatible – Designed for BMX racing drivetrains with one gear ratio

Technical Specifications

• Type: Threaded freewheel
• Application: BMX racing, single-speed

Compatibility and Ideal Use Cases

This freewheel is compatible with rear hubs that use threaded freewheel mounting (standard thread pattern). Not compatible with cassette hubs, freehub bodies, or fixed-gear setups. Verify your hub type before ordering—cassette hubs require cassette cogs, not threaded freewheels. Ideal for riders using traditional threaded freewheel hubs who need a replacement freewheel for racing. Works with standard BMX chains and cogs. The threaded design allows for easy installation and removal with a freewheel removal tool.
