Matters´ original high-performance racing wheel is the Super Juice. It was the first-ever Matter wheel to use Hollow Core Technology. This core has been fundamental to Matters' success over the years. The Hollow Core allows us for a very stiff core, without the added weight of a traditional single-piece core. The Super Juice wheel is perfect for road and marathon events because of its fast-rolling performance and grip. This wheel comes in 90mm and F1 / 86A. BEAT YOUR BEST.
