Cervelo Threaded Thru-Axle Fork Insert

If you have managed to damage or lose the Threaded Axle Insert for your Cervelo disc brake, threaded thru-axle fork, this may be the part for you. The item consists of the threaded receiver and Hex bolt used to affix it to your fork. While this does fit many threaded thru-axle Cervelo Disc Fork models, see the list below for full compatibility.
