SRAM Red GXP Crankset - 53/39

Putting the power to the pavement, the stiff, smooth and strong SRAM Red crankset is poised to dominate. Fatigue, flex and friction are enemies that rob you of speed and performance over both the short and long terms; Red does its part to keep them from affecting your ride. Integrated carbon spider is designed for a light weight and extreme stiffness, promoting instant, efficient power transfer. Red's new hybrid ceramic bearings, housed within the case of the GXP™ bottom bracket, virtually eliminate speed-sapping friction. Ceramic bearings riding in a stainless-steel race use a lighter seal than typical bearings; as a result and are also lighter, stiffer, more efficient and more durable. Includes an equally revolutionary pair of chainrings optimized exclusively for Red components. Because they're designed for extreme stiffness, chainrings improve efficiency and provide incredible power transfer. Produced in limited production runs, SRAM Red components are crafted with 3 key factors in mind—advanced materials, light weight and premium efficiency. BCD = 130. Bottom bracket cups sold separately.
