Shimano R9270-C60 Dura-Ace Tubeless Clincher 60mm Front Wheel

Perfect for flatter courses and time trials, the DURA-ACE C60 prioritizes aerodynamic efficiency and lateral rigidity. The new hub design, stiffer spokes, and deep section rim are designed specifically to allow you to push harder in corners and ensure that every bit of your effort is translated into forward motion.

Like the entire DURA-ACE wheel family, the new C60 started with a blank slate. Different from the C36 and C50, the C60 has a specific front hub design using Shimano's OPTBAL 2:1 spoke pattern to enhance lateral rigidity. The C60 also receives stiffer spokes, 1.8 mm instead of 1.5 mm. Tested by our professional athletes, this focus on the lateral rigidity of C60 allows you to push harder in corners and when maneuvering at higher speeds. Lastly the new wind-tunnel tested, deep section rims feature a faster, more stable cross-section that time trialists, triathletes, and sprinters alike will enjoy.
