FAQs

Can I use these for road racing?

They are designed for time trials and triathlon, and many events restrict disc wheels in road races. For road racing choose the C50 or C60.

Will it work with my groupset?

The rear disc uses Shimano's 12-speed road freehub, so it fits Dura-Ace, Ultegra and 105 12-speed cassettes, including on Dura-Ace R9200 TT builds. Brakes are disc only with Centre Lock rotors.
