The massive 40mm x 37mm Mag Core performs like a backbone, supporting the wheel and road surface shape under heavy side loads, and helping to maintain exit speed and straight line acceleration. Featuring a slightly offset race shape, designed for a predictable breakaway point and controlled slides, the Shred Mags are poured in Road Rider's exclusive High Rebound 80a formula.
