This one takes all your trail dreams, from XC to enduro, all the way to eleven. SRAM's XX1 rear derailleur packs a massive amount of technology into its compact, lightweight body.

This self-lubricating, one-way roller clutch controls your chain tension to eliminate chain slap and give you smooth, consistent shifts over any terrain. For quicker, smoother, more exact shifting, the large upper pulley's offset design maintains a consistent chain gap across all gears.
