SRAM RED 10-Speed Rear Derailleur

The SRAM RED Rear Derailleur has been designed to deliver the performance advantage you've come to expect from SRAM. The derailleur is designed for 10-speed applications with our Exact Actuation technology for precise, efficient shifting.

Features:

• Exact Actuation shifting provides fast, accurate shifts.
• More clearance with 28T cassettes thanks to longer B-knuckle.
• Silent shifting with optimized AeroGlide lower pulley, ceramic bearings
• Spring-fixed barrel adjuster
• Titanium pinch bolt keeps a low profile while minimizing weight
• WiFLi option

Technology:

• AeroGlide Pulleys: New tooth pulley design with a sound damping effect for a super efficient and silent ride experience. Bottom and top pulleys benefit from this feature.
• EXACT ACTUATION: When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement). EA helps to simplify and stabilize 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.
• WiFLi: WiFLi = Wider - Faster – Lighter. SRAM's WiFLi Technology is based on the compact 2 x 10 or 11 - two front chainrings and 10 or 11 gears in the rear - design inherent in SRAM RED 22, Force 22, Rival 22 and Apex, which delivers a wider range of gears, up to 11-32, than your standard triple, faster shifts through two chainrings and every gear on the rear cassette, and with significant weight savings. WiFLi cassettes are also available for Force CX1.
