SRAM's 11-speed mechanical road groupsets — Red 22, Force 22, Rival 22 — all rely on the same Exact Actuation cable pull ratio, which means the rear derailleur you hang off the frame determines how much cassette range you can run and how much your drivetrain weighs. The Red 22 WiFli sits at the top of that hierarchy. It's the medium-cage version built to swallow cassettes up to 32T, which is the setup you want if you're running compact gearing on a bike that sees real climbs, or if you've been running an 11-28 and finally admitted you need one more gear in reserve.

The WiFli designation (Wider, Faster, Lighter) covers the extended B-knuckle geometry and longer cage that let this derailleur clear a 32T cog without the chain running out of wrap in the small-small combination. Pair it with an 11-32 cassette and a compact 50/34 crankset and you have a 1.06 low gear ratio, which is what makes long sustained climbs manageable without swapping to a triple or moving to a 1x setup. It shifts the same 11-speed DoubleTap shifters you already have on the bar — no compatibility gymnastics.

Weight lands at 165 grams, which is where the price jump over Force and Rival goes. Carbon outer cage, carbon inner links, and titanium hardware do the work, and the AeroGlide pulleys run ceramic bearings inside a vibration-damping polymer body. The result is a rear derailleur that runs quieter than the Force 22 equivalent and drops roughly 30 grams off it. If you're already invested in the 11-speed mechanical ecosystem and want the flagship version of the derailleur without moving to AXS wireless, this is it.... Read More
