The SRAM Red Braze-on Adapter allows you to take full advantage of the new SRAM Red Yaw Front Derailleur if you have a standard down tube without a braze-on mount point. The spotter keeps your chain from falling into your bottom bracket cluster and damaging your frame, or worse — ruining your Tour.
The SRAM Red Braze-on Adapter is available in either 31.8 or 34.9mm clamp diameters.
Needed for etap
Familiarity: I've used it several times
Just what I needed to mount my etap front derrailuer as my bike does not have a built in braze on area and the shimano clamp didn’t fit the derailleur great.
