The Sram Red 22 Groupset - No Chainset (OE) is loaded with features and benefits that match the needs of professionals. Sram designed Red to be fast, light, aerodynamic, ergonomic, near-silent, and, of course, trim-less with their ground breaking Yaw technology. Adding two more gears to that combination was arguably the only improvement required and they added that benefit, without adding weight, maintained a system that shifts incredibly fast upfront, and with the best and smoothest gear transitions in back. There is no compromise and no trim, what Sram are calling True 22, in any gear combination.
