If you own a braze-on front derailleur then purchase a frameset that requires a clamp-on front derailleur, this is what you need so you can keep using the derailleur you already own. It transforms a braze-on derailleur into a clamp-on style in a matter of moments.

These clamps are compatible with both Shimano, Sram, ACCURA, and Campagnolo front derailleurs.
