The CDX series represents the pinnacle of Gates Belt Drive technology. CDX stands for best materials, highest manufacturing standards and innovative design solutions.

CDX components guarantee maximum efficiency and durability with perfect function. This makes them the first choice for anyone who uses their bike or e-bike daily, excessively, or as a piece of sports equipment, 365 days a year, under the highest loads, in all track conditions and in any weather. Gates CDX belts have extra reinforced carbon fibers and an extra abrasion resistant polyurethane tread. CDX components are the strongest and most durable belt drive components, making them ideal for use on mountain bikes and EMTBs with mid-mounted motors and high torques.
