Comfort joins speed. The new R 23 SPLINE® wheels work perfectly with the new breed of wider road tires. The combination of wide rims and wide tires results in more comfort in the saddle and more grip on the road. The rider ends up with faster and more enjoyable rides. Together with the laterally stiff build which uses high end bladed spokes, the R 23 SPLINE® lets you tackle the last climb of the day with enough energy to enjoy the looks of the hubs and to plan your next big ride.
