Whether you're riding with your friends after work or competing in an event, this crankset is engineered to keep your momentum flowing. It features a hard-wearing aluminium construction which makes it more than capable of handling all the abuse from longer-journeys & intense road cycling events. SRAM has also put this race-ready crankset through a CNC-machining process, which shaves off any unnecessary weight. This means you'll benefit from its amazing torque levels without worrying about any excess weight holding you back from the podium. Technologies: X-SYNC: SRAM 1X chainrings provide the highest level of performance & durability. Their tall square teeth edges engage the chain earlier than traditional triangle shaped teeth & their sharp & narrow tooth profile, as well as their rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chainrings have been designed with mud-clearing recesses for the inner chain links & rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrain. Manufacturer Part Numbers: 50T: 00.6118.371.001 38T: 84916166
