Derailleurs

Shimano Deore XT Shadow + Rear Derailleur (Long Cage)
$109.99
Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. Plus-type derailleurs use a lever-actuated clutch spring to prevent chain slap, reduce noise while on the trail, and improve chain engagement when riding over rough terrain. Sealed pulley bearings keep things spinning smoothly, and wide plate construction prevents the derailleur from getting clogged with mud and debris.
SRAM XX1 Eagle Type-3 Rear Derailleur
$300.00
This derailleur not only answers the Eagle drivetrain’s need for greater capacity, but is also the next evolution of SRAM's proven, 1x-specific X-HORIZON design. The larger, 14-tooth X-SYNC lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle’s overall smooth-pedaling feel. SRAM's Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle derailleur’s performance and overall durability.
Shimano Deore XT Shadow Rear Derailleur (Mid Cage) (Top-Normal)
$94.99
Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. The Shadow design tucks the rear derailleur closer to the wheel, which keeps it out of the way of roots and rocks as you're flying down the trail. A strong spring prevents chain slap, reducing noise while on the trail, and improving chain engagement when riding over rough terrain. Sealed pulley bearings keep things spinning smoothly, and wide plate construction prevents the derailleur from getting clogged with mud and debris.

SRAM X01 Type 2.1 Rear Derailleur
$214.00
SRAM's X01 Rear Derailleur packs a massive amount of technology into its compact, lightweight body. This 11-speed gear changer uses a “horizontal parallelogram” design that limits all movement to the horizontal axis, reducing the force it takes to shift. The Type 2 clutch is brilliant. 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.
