The new Sram Rival 22 rear derailleur is one out of many components of the new Rival 22 11 speed groupset. With the introduction of the Rival 11 speed series, Sram made the 11 speed available for a small price.
The Rival 22 rear derailleur is equipped with the same technology as its bigger brothers, the Force 22 and the Red 22. The biggest difference is its weight. Not using a carbon cage and using steel bolts and pins in this derailleur brings it weight up to 180 grams.
The Rival 22 rear derailleur uses a Exact Actuation shifting mechanism what makes this derailleur shift on a 1: 1 ratio, every click means movement to another sprocket. The new Aero Glide jockey wheels ensure a muted shifting sound.
There is a short and a WiFli cage available for the Rival 22 series. The short cage can handle cassettes up to 28 teeth, the WiFli cage can handle cassettes up to 32 teeth.
