SRAM Red E1/XX SL AXS Eagle 1x Gravel Transmission Drivetrain

Designed to be the ultimate gravel drivetrain: resilient, precise, light and fast

Attaching to frames with the UDH interface, the XX SL Transmission rear derailleur eliminates variables by centering on the rear axle for a precise fit and superior impact resistance. It’s simpler, stronger, with no need for a hanger. Fast, precise shifting with simple setup.

XX SL Eagle Transmission is for riders who demand more out of themselves, and their machine. Because power to weight is everything when flying off the line. Precise shifts under load, unprecedented strength, race-winning weight savings. XX SL leaves nothing left to desire, and nothing left to chance.

One-finger braking from anywhere, with less effort. RED brakes require 80% less effort than before when braking from the hoods, and 33% less effort from the drops. More power and less hand fatigue means you’re in control on any surface.

Say goodbye to anticipatory shifts where the terrain forces your hand. Eagle Transmission gives you the power to shift when and how you want. For the first time, you can pedal at full output while you shift – inboard or outboard. Cassette Mapping provides precise shift points while X-Sync tooth profiles maximize chain engagement, so no effort is wasted in the system to translate yours into one thing – propulsion.

The lightest Eagle cassette ever – a massive 520% gear ratio at a scant 350 grams. Spider Cog realizes the biggest weight savings possible with its all-aluminum construction for the largest three sprockets. The entire cassette is finished with an exceptionally durable Hard Chrome, because what good is lightweight if it doesn’t last, race after race?
