As gravel riding is pushed to unthinkable limits, so is technology. SRAM RED XPLR 1 x 13-speed drivetrain is here to propel you forward and into the future. The hollow carbon arms paired with DUB Wide spacing allow more room to go big on tires and drown out the toughest gravel routes. Thread Mount technology means riders can run a small ring for big elevation days, and then easily swap to a larger tooth count ring when maximum flat-out speed is a must. Capture every detail with Power Spider Meter's foolproof accuracy. With dual-sided measurement, fitness goals are always within reach. Long battery life keeps you riding day after day while the weatherproof design shrugs off harsh conditions only found on remote gravel roads.
