All models use the same mold, which means that all Exceed models share the same core design features and frame shaping. The three different carbon frame platforms (CF, SLX, and CFR) differ, however, in material content and layup. With the new CFR we went further than ever before on a mountain bike and achieved an incredibly low weight, making it our lightest hardtail frame to date and definitely one of the lightest frames on the market.
