Developed using Turbulent Aero data and technology, the 34|37 TA is designed to help get you up those mountain passes as fast as possible. Now 30 grams lighter per rim, and 4 grams faster in the wind tunnel, the 34|37 wheels have a lifetime warranty supported by a no-fault crash replacement. And in keeping with Reserve workmanlike ways, you’ll find external nipples, standard spokes, no tire limitations with a semi-hooked design and no rider weight limits.
