The SRAM Schaltwerk Red Aero Glide WiFLi rear derailleur is designed for riders who demand fast, precise shifting and a clean aerodynamic profile on their road bike. As part of SRAM’s high-end Red series, this derailleur is built to deliver crisp gear changes under load, whether you are sprinting, climbing, or rolling along in the bunch. The Aero Glide design focuses on smooth, quiet operation, helping the chain move confidently across the cassette while reducing noise and friction for a more refined ride feel.
Featuring SRAM’s WiFLi concept, this rear derailleur is optimized for a wider gear range than traditional short-cage road derailleurs, making it ideal for modern cassettes with larger sprockets that offer easier climbing gears. This gives you the versatility to tackle steep climbs without sacrificing high-speed performance on the flats. Lightweight construction, race-proven ergonomics, and compatibility with SRAM road shifters make the Red Aero Glide WiFLi a premium upgrade for performance-focused cyclists who want reliable shifting, efficient power transfer, and a sleek, professional look on their drivetrain.
