The Shimano WH-R8170 wheelset has 50 mm high carbon rims and is the perfect addition to your Ultegra R8100 road bike group with center-lock disc brakes. Unlike Dura-Ace R9200 wheelsets, its steel pawl freewheel is compatible not only with 12-speed cassettes, but also with 11-speed cassettes. The model scores with a lot of aerodynamics, tubeless compatibility and rigidity at a pleasantly low weight. The rims have an internal width of 21 mm for up to 32 mm wide tires and feature the wind tunnel-tested D2 design. They are each fitted with 24 tapered stainless steel spokes, with a specific lacing pattern being used on the rear wheel to balance the spoke tension.
