Profile Design 1/Fifty Clincher Wheelset

Overview

The 1/Fifty is a wide, deep profile, full carbon aero rim that successfully blends crosswind stability, stiffness and handling while delivering superior heat dissipation and braking performance by utilizing the same ultra high TG resin and brake pads as the TwentyFour series wheels. The semi-automated carbon lay-up, rim construction and raw materials proven through the TwentyFour series wheels are exemplified in the 1/Fifty rims. By utilizing components optimized for more efficient production, we are able to deliver a performance wheelset at an aggressive price.

Brake Performance

Specifically formulated to withstand the same heat our rims can take on, our brake pad compound is exclusive for GMRÂ wheelsets. Using a specially formulated rubber compound, durometer and friction agent, we developed a proprietary brake pad and reduced braking distances over that of other carbon fiber wheelsets.Â
