Always in the right gear. With its 13-speed drivetrain system and wide gear range, the advanced RED XPLR AXS series is the spearhead of SRAM's Gravel lineup. While the close-ratio XG-1391 cassette ensures efficient propulsion in every situation, the durable Full Mount rear derailleur can withstand anything its rider throws at it. Complemented by significant weight savings ans brakes that can be operated with just one finger, the RED XPLR components allow the bike to fly over every route with full power.

When the terrain becomes more challenging and the pace quicker, you need the right gear range to keep moving and the optimum gradation at all times so that you don't lose touch. The XG-1391 cassette from SRAM's RED XPLR series offers the additional coverage that Gravel bikers with a 1-speed drivetrain need. This 13-speed cassette not only makes steep climbs easier, but also features the narrow gradations for fast sprints. Even on the most demanding routes, riders can enjoy improved gear shifting quality, which the extremely light cassette, weighing just 288 grams, achieves with the help of optimized shifting aids on each sprocket.
