SRAM GX Type 2.1 10 Speed Rear DerailleurThis SRAM GX 10-speed rear mechanism is developed to work with the SRAM 10 speed MTB shifters and a 2x chainring setup. Using a 1:1 cable pull ratio and a rolling bearing clutch this tough component will ensure you have a crisp and precise gear change.Leveraging the legendary history of SRAM shifting, the GX 2x10 rear derailleur provides incredible shifting speed and precision. EXACT ACTUATION technology eliminates chain slackness and shifting variation. ROLLER BEARING CLUTCH technology delivers maximum drivetrain stability-even through the most punishing terrain. And with CAGE LOCK technology, wheel removal and installation are easier than ever.Features: Material: Aluminium Speed: 10-Speed Mount Type: Standard hanger mount Compatibility: Exact Actuation Recommended Group: GX 2x10 Maximum Cassette Low Sprocket Capacity: 36T Shifter Capability: SRAM 10 speed flat bar shifters ONLY Cable Pull Ratio: 1:1 SRAM Part No. RD-GX-T21-A1 Weight: 302gCage Length Information:Short Cage Option: Total chain wrap capacity of 30T (Ideal for use with downhill (DH) / enduro bikes with a smaller chainring up front)Medium Cage Option: Total chain wrap capacity of 35T (Ideal for use with all mountain (AM) / trail bikes with a medium chainring up front)Long Cage Option: Total chain wrap capacity of 47T (ideal for use with touring bikes with a larger chainring up front)Technologies: Exact Actuation - SRAM launched their road technology from scratch, they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilise the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way. Cage Lock: With this technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place. Roller Bearing Clutch: Rear derailleurs with the technology deliver maximum drivetrain stability, even through the most punishing terrain. With Roller Bearing Clutch technology, derailleur bounce and chain slap are eliminated without sacrificing precisionBuy SRAM Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
