SRAM's WiFli (aka mid-cage) derailleur works with cassettes up to 32 teeth. WiFLi delivers a wider range of gears than your standard triple. Shifts are much faster through two chainrings and every gear on the rear cassette. Plus there is significant weight savings over a triple. WiFli allows easier climbing up steep hills without sacrificing shift quality.
The Rival 22 rear derailleur features SRAM's Exact Actuation for precise, even gear changes throughout the shifting range. Exact Actuation delivers a perfect adjustment from gear to gear. SRAM's road derailleurs descended from their legendary MTB rear derailleurs so they can take a lot of hard use. The Rival 22 rear derailleur only weighs 191 grams, but it has an all-aluminum B-knuckle inner link and tough alloy cage that will stand up to any serious rider demands.
SRAM uses the latest in pulley technology called AeroGlide to ensure a quiet and smooth drivetrain. A new tooth pulley design creates a sound damping effect for a super-efficient and silent ride experience. Both the bottom and top pulleys benefit from this feature.
Compatible with cassettes from 11-26 to 11-32
