Shimano's Dura Ace WH-R9170 C40-TL Disc Wheelset features disc-specific, 37 mm deep, tubeless-ready carbon rims for speed and confidence in all conditions. Laced to Shimano's dependable hybrid angular cup-and-cone bearing hubs, the R9170 C40 wheels have durable smooth-rolling performance, and out back, the OPTBAL spoke lacing and offset rim profile use a 2:1 ratio for even spoke tension to make a stronger wheel. A titanium freehub shaves even more weight to make the C40 a mid-depth wheel that can climb as well as it sprints.

Compatible with Shimano/SRAM 9/10/11-speed cassettes and Centerlock rotors. 12 mm thru-axle front and rear.

Efficient mid depth wheels

Im using these on my Cervlo C5. The HED Ardennes that came with the bike are great for gravel because theyre a bit compliant. But theyre not as stiff and efficient for climbing and fast rides on pavement. The DA 9170 wheels are very stiff and efficient while also being about 100 gr lighter. The ride quality reflects the carbon construction soaking up road buzz. In high speed turns theyre laterally stiff and stable. DA hubs are exceptional.
