ZTR Valor carbon wheelset. The Valor features the first carbon rim with genuine NoTubes' Bead Socket Technology for tubeless use. Available in 26", 27.5" and 29" sizes, with multiple axle options and an 11-speed XD driver option, the Valor features the 3.30Ti Disc hubs, 24/28 spoke pattern and individually reinforced spoke holes. The added rim width and lower sidewalls of NoTubes rims increase tire volume for less rolling resistance. Far from just another "carbon copy," the more precise and consistent manufacturing process developed for the carbon fiber rim of the Valor sets a new standard in tubeless technology and carbon fiber rim design.
