SRAM RED XPLR AXS Upgrade Kit rear derailleur 13-speed | cassette XG-1391 | 10-46 teeth
With this upgrade kit, you can convert your gravel or all-road bike with an existing SRAM AXS drivetrain to the Red 13-speed XPLR AXS drivetrain.
SRAM Red XPLR AXS 13-speed rear derailleur
The loads on gravel bike rear derailleurs are significantly higher than on road bikes. Not only impacts from the ground, but also flying stones and sticks can easily damage the rear derailleur. This is why SRAM has incorporated some technologies from the proven Transmission mountain bike rear derailleurs in the development of the new RED XPLR rear derailleur. Thanks to the full-mount design for mounting on frames with UDH derailleur hanger, the rear derailleur is significantly more robust and resistant than the previous version. The rear derailleur can independently avoid hard impacts by briefly decoupling. Should a component be damaged, numerous components can be replaced. The rear derailleur has been specially designed and optimized for use with the RED XPLR 10-46 tooth cassette, making it easier than ever to set up the rear derailleur without the need for adjustment screws. With the spring clutch inspired by mountain bikes, the chain sits securely on the chainring even under the toughest vibrations. Another highlight is the lower Magic Wheel derailleur pulley, adopted from the Transmission rear derailleurs. It keeps the chain moving even if a stick blocks the roller.
NOTE: The rear derailleur is only compatible with SRAM AXS shifting components!

SRAM Red XG-1391 cassette | 10-46 teeth
Gravel bikes place special demands on the gear ratio. On the one hand you need small gears for the steepest ramps and long climbs, on the other hand you need a fine gradation to have the optimum cadence on long flat sections or in the finish sprint. To master this balancing act, SRAM has upgraded the new Red XPLR cassette to 13-speed. With 46 teeth, the largest sprocket has also been increased by 2 teeth, thus extending the range. Similar to the Transmission mountain bike cassettes, the largest sprocket has an offset to the spokes. Thanks to this design, the XPLR 13-speed cassette is compatible with a conventional SRAM XDR freehub body and with all SRAM 12-speed flattop chains. Thanks to the optimized shifting characteristics on each sprocket, you can enjoy the best shifting quality even on the most demanding routes. With a weight of just 289 grams, the cassette is also significantly lighter than the 12-speed XPLR cassette. The low weight was achieved through a revised X-Dome construction. The first 10 sprockets are milled from a block of hardened steel. The final sprocket is made of aluminum and also acts as a spider for the 32- and 38-tooth sprockets, which are also made of aluminum and riveted on.
