SRAM RED XPLR Upgrade Kit - AXS | 1x13-speed | E1

RED XPLR – Effortless Resilience. Effortless Precision.

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.

Composition of the SRAM RED XPLR AXS upgrade set:

• RD-RED-1E-E1 | RED XPLR AXS rear derailleur
• CS-XG-1391-E1 | RED XPLR cassette (XG-1391, XDR, 10-46 teeth)

Supplied without battery. This can be ordered separately.

SRAM RED XPLR AXS rear derailleur

Gravel riding demands pretty much everything from the bike, but the RED XPLR rear derailleur from SRAM can take it all in its stride. Regardless of whether it is confronted with wood, stones or airport luggage, the robust Full Mount rear derailleur for frames with a hangerless UDH interface always guarantees reliable and precise functioning of the shifting system. This is not least due to the lower derailleur pulley, the so-called Magic Wheel, which ensures optimum chain management and continues to rotate even if an object gets stuck. While configuration is easier than ever before without adjustment screws, the familiar AXS wireless technology makes pairing and setup as intuitive and reliable as ever.

• specific for 1x13-speed drivetrain systems
• optimized for use with the XG-1391 cassette (10-46 teeth) and Flattop™ chains
• use of numerous replaceable and rebuildable parts
• simple setup without adjustment screws
• superior chain management with MTB-inspired spring clutch
• hangerless interface, Full Mount attachment
• lower Magic Wheel derailleur pulley for unobstructed chain movement

Note: Designed to mount on frames that have the UDH specification (Universal Derailleur Hanger) with an interface without derailleur hanger.

SRAM RED XPLR XG-1391 cassette

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.

• extended gear range of 460 % (10-46 teeth)
• designed for use with XPLR 13-speed rear derailleurs
• suitable for XDR freewheel bodies
• compatible with all Flattop™ road bike chains
