ICAN 56mm Carbon Road Bike Wheelset Clincher Tubeless Ready Basalt Brake Surface Rim 6 Pawls Hub Shimano 10/11 Speed 56MM DEEP CARBON RIM. MAXIMUM AERODYNAMICS, CROSSWIND STABILITY-ICAN 56mm rim is the most aerodynamic rim that does not suffer from loss of stability in crosswinds. Ideal for the all around rider that focuses more on long flat rides, but also rides in a fast groups and hill climbs FULL CARBON CLINCHER. HIGH STRENGTH CARBON FOR LIGHTWEIGHT PERFORMANCE-using the latest carbon forming technology, we are able to build a very strong rim from carbon only. A critical area for durability, the tire bead hook of clincher rim is up 73% stronger than other carbon clincher rims. This makes wheel that is very light with positive braking performance and reliable durability 25MM WIDE RIM, INCREASED AERODYNAMICS AND IMPROVED HANDLING-the rim's 25mm width improves aerodynamics by creating a more uniform airflow over the wheel, balancing the aerodynamic forces of the rim with the leading edge of the tire AERO BLADED SPOKES-incerase Wheel Strength and Improve Aerodynamic Speed ICAN standard road bike hub R13-Shimano 10/11 speed(default) Campagnolo 10/11 speed(available)
