Precise, quiet, and race-proven, the Red Front Derailleur Package is ready
What Our Gearhead® Experts Are Saying:
"This is the front derailleur I reach for when someone is building a full mechanical Red groupset and will not tolerate any weak links in the drivetrain. The dual-material cage is the standout detail: aluminum outer for weight savings, tool steel inner for the kind of stiff, immediate response you expect at this level. Pair it with the adapter, and it opens up a wide range of frame options that a braze-on derailleur would otherwise be locked out of entirely."
At the top of SRAM's mechanical road lineup, the Red Front Derailleur Package is the choice for builds where front shift performance is non-negotiable. Paired with the Braze-On Adapter, it extends that flagship performance to round seat tubes measuring 31.8mm or 34.9mm in diameter, making it a complete solution for custom builds, older frames, and any road setup without a dedicated front derailleur mount.
The Red Front Derailleur's cage construction reflects the engineering priorities of the Red groupset. The aluminum outer cage reduces rotational mass and overall system weight, while the tool steel inner cage provides the rigidity needed for sharp, low-effort front shifts under load. Yaw technology drives the cage's rotational movement, keeping it in continuous alignment with the chain across the full spread of rear cogs and eliminating the need for shifter trim entirely. The independently mounting Chain Spotter adds frame protection without mechanical interference, and precision install markings take the guesswork out of setup at the bench.
Optimized for SRAM's X-GlideR chainrings in 50/34T and 52/36T configurations, with a 45.0mm chainline and a chainstay angle range of 61 to 66 degrees, this package is dialed for road race geometry and suits any 2x11 SRAM Red mechanical build. Bottom pull cable routing keeps the installation clean across a wide range of road frame designs, and the slim spring profile eliminates frame interference without compromising shift performance.
