The Caledonia-series framesets have ample room for 34mm tires, but many riders want the capability to run fenders as well. Cervelo offers you enough frame and fork clearance for 31mm tires and many fender set options. This Fender Mount Assembly kit 302A features all the hardware and Caledonia-specific parts you will need to mount fenders. The system utilizes the thru-axles and special mount inserts and a seat stay bridge assembly to create the proper mounting points, along with a fork crown boss. A frame protector kit is supplied for the parts that assembly to the seat stay bridge.
