Trimming the front derailleur across the cassette has been part of riding a double-chainring drivetrain for as long as front derailleurs have existed — until SRAM's Red 22 front derailleur used Yaw technology to eliminate the need for shifter trim, rotating the cage to maintain a consistent angular relationship with the chain instead of simply moving back and forth . That single change is what makes this derailleur different from every mechanical front derailleur that came before it, and it's the reason SRAM Red 22 drivetrains shift the way they do across all 11 cogs without cage rub.

The mechanism works by rotating the cage on a vertical axis as it moves outboard, so the cage stays parallel to the chain regardless of which cog you're running in back. In practice, that means you can cross-chain from the big ring to the largest cog, or the small ring to the smallest cog, without touching the shifter to nudge the cage over. It's a real quality-of-life improvement on climbs and rolling terrain where you're constantly moving between chainrings.

Compatibility is where this derailleur gets specific, and it's worth being clear before you order. It's compatible with SRAM Red 22 and SRAM Force 22 only — the Yaw shift ratio doesn't work with older 10-speed SRAM road drivetrains, Rival 22, or anything from Shimano or Campagnolo. It's also mechanical only, so if you're running eTap or AXS, this isn't the derailleur for that bike. Pair it with X-GlideR chainrings and Red or Force 22 DoubleTap levers to get the shifting SRAM designed it around.... Read More
