The CL 40 full carbon disc clincher is the perfect all-around disc wheel. The aerodynamic, optimized rim shape slices through the wind while preserving the confident, stable handling of a box section rim. A wide internal rim width provides an optimal tire profile for incredibly precise handling and stiffness. The center lock hub makes this an ideal wheel for the muddiest 'cross race or fast-paced ride. This wheel offers a non-SCS rear hub for traditional QR or 12mm thru-axle compatibility.
