Bontrager Rhythm/Line Freehub Body

This freehub body is designed specifically for Bontrager Rhythm Pro, Rhythm Elite, and Line wheelsets that utilize an 11-speed drivetrain. Before purchasing, verify that your current hub matches the Rhythm or Line series specifications, as it is not a universal part for all Bontrager wheels.

Yes, this is a complete replacement freehub body that typically arrives ready to install. However, it is always good practice to inspect your existing axle and end caps to ensure they are clean and in good condition before reassembly.

This freehub body is intended as a direct replacement for existing 11-speed setups on compatible Rhythm and Line wheels. While it is designed for 11-speed cassettes, compatibility with older 10-speed hubs depends on your specific hub shell generation; we recommend checking your hub's serial number against Bontrager's compatibility charts.

Replacing a freehub body is a moderate task that requires basic bike maintenance tools, such as a cassette tool and cone wrenches. If you are comfortable removing your cassette and axle, you should be able to perform this swap, but if you are unsure, a local bike shop can handle the installation quickly.

You generally need to replace a freehub body if you notice excessive play or 'wobble' in your cassette, if the pawls are failing to engage properly, or if the bearings have become rough and gritty. Replacing it restores the smooth, reliable power transfer you expect from your drivetrain.
