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.
