What Our Gearhead(R) Experts Are Saying:"I put this on a dedicated road race build, and the difference in front shift quality was immediately obvious. The Yaw cage tracks with the chain so smoothly that cross-chaining just stops being something you think about mid-ride. The Chain Spotter is a nice touch since it gives real peace of mind on hard efforts where a dropped chain would cost you dearly."Deep into a road race effort, the last thing on your mind should be your front derailleur. The Red Front Derailleur Package from SRAM is built to keep it that way. Whether you are bridging to a break or drilling it on a long false flat, this package puts quiet, confident shifting at the top of your drivetrain and keeps it there. The Red Front Derailleur pairs an aluminum outer cage with a stiffer steel inner cage, shaving weight where it can while delivering punchy, authoritative front shifts when it matters. The independently mounting Chain Spotter protects your frame without adding mechanical clutter, and the Braze-On Adapter brings the full package to round seat tubes in 31. 8mm or 34. 9mm diameters that would otherwise lack a mounting point entirely.
