ZTR Valor carbon wheelset. The Valor features the first carbon rim with genuine NoTubes' Bead Socket Technology for tubeless use. Available in 29er now and 26", 27.5" sizes coming later this year, 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.
“The truth is we could have made a carbon fiber rim years ago,” said Stan Koziatek, CTO and Co-Owner of Stan’s NoTubes, “but it wouldn’t have been a genuine NoTubes rim. High Spots of extra resin, ragged seams and overlaps, and shape and width deviations have somehow become acceptable on wheelsets costing several thousand dollars, but we require much higher tolerance. It took us years to find a technology and manufacturer able to consistently produce this rim”
