Gravel throws just about everything at your bike, and the SRAM RED XPLR AXS rear derailleur will happily take it all. Bring on the sticks, stones, and airport baggage abuse because the Full Mount derailleur design fits onto frames with the hangerless interface to make for the most robust and reliable gravel drivetrain possible. No adjustment screws mean setup is simpler than ever. And a surprise stick is no match for the Magic Wheel, as the debris-resistant lower pulley keeps the chain moving at all times. Purpose built for gravel, this 1x specific unit prioritizes shift precision and chain management no matter the terrain or conditions.
