Please select options


Shimano's Dura Ace WH-R9100 C40 Clincher Wheelset utilizes a lightweight carbon laminate over ultra-thin alloy rims to balance stiffness, durability, and ride quality, and the hybrid angular cup and cone bearings ensure they roll silky smooth while only requiring a 5 mm hex key for adjustments. OPTBAL 2:1 rear spoke lacing uses twice as many spokes on the drive side to even out spoke tension for a stronger wheel that stays true.

Compatible with Shimano/SRAM 9/10/11-speed cassettes. Includes quick release skewers.
