Got a braze-on front derailleur, but a frame that needs a clamp? Not to worry bud, SRAM has you covered. The 2013 SRAM Red braze-on front derailleur adaptor is a specially designed clamp that will make a SRAM Red YAW braze on front derailleur compatible with your clamp on frame. So why not just use a normal clamp? Braze-on derailleurs usually have a specially shaped and designed hanger to fit the braze-on tab, so you need a clamp with a braze-on tab to fit it.
