today announces the 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 a 3.30 Disc Ti hub, 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.
Claimed to be lighter and stronger than their aluminum rims, the Valor’s carbon rim lay-up is engineered to absorb radial vibrations adding suspension to a bike, making the ZTR Valor Carbon the most advanced wheelset NoTubes has ever produced. ZTR Valor utilizes a construction that is both elastic and strong. Stan's NoTubes has constructed a light weight carbon fiber rim design not only to be stronger than aluminum but also to perform better in real world riding conditions. Prices are not set yet, but the tentative target is $1900 and they will be available in 2014.
“The truth is we could have made a carbon fiber rim years ago,” explains Stan Koziatek, “But it wouldn’t have been a genuine NoTubes rim. We require a much higher tolerance. It took us years to find a technology and manufacturer able to consistently produce this rim.”
