SRAM RED® WiFLi™ Rear Derailleur 10-Speed

The SRAM RED® Rear Derailleur has been designed to deliver the performance advantage you‘ve come to expect from SRAM. With WiFLi, the rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette.  The new range of gears is wider than the standard triple chainring system and saves well over 250 grams.

We‘ve paid rapt attention to the finer details, like adding a hollow titanium anchor bolt and even refining tooth geometry of the jockey wheel. The result is that the chain runs through the RED rear derailleur smoother and quieter than ever before.

  • Exact Actuation™ shifting provides fast, accurate shifts
  • 32T clearance thanks to the mid cage design: widest gear range available
  • New silent shifting with optimized AeroGlide lower pulley, ceramic bearings
  • New spring-fixed barrel adjuster
  • New chain pulley cage adds precise chain management
  • Titanium pinch bolt keeps a low profile while minimizing weight

When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. EA helps to simplify/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.

SRAM's WiFLi™ technology accommodates a wider range of gears than a standard short-cage road derailleur. Compared to a triple chainring setup, it provides faster shifts and significant weight savings.
