Specialized Formula Sealed Cartridge Freehub Body

No, it is specifically engineered for 2021 models of the Specialized Aethos, Roubaix, and Tarmac. Please verify your specific hub configuration before purchasing to ensure a proper fit.

This component is primarily used to upgrade your bike to a modern 12-speed drivetrain system. It is also a necessary replacement part if your existing bearings have worn out or if the freehub body has sustained damage.

This unit is designed for the SRAM XDR driver body standard. It will not work with standard Shimano HG or other cassette interfaces.

This freehub uses sealed cartridge bearings, which are designed for long-term durability and smooth rotation. While they are generally considered a 'replace rather than repair' component, they offer excellent protection against the elements compared to open bearing systems.

If you are comfortable performing standard drivetrain maintenance and have the necessary tools to remove your cassette and axle end caps, this is a straightforward swap. If you are unsure about your hub's specific disassembly process, a professional mechanic can ensure it is installed and torqued correctly.
