If you own a braze-on front derailleur and 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 front derailleur into a clamp-on style in a matter of moments. You'll need to choose one of three sizes -- 28.6mm, 31.8mm, or 34.9mm (aka 1-1/8", 1-1/4", and 1-3/8" respectively).

Two notes of interest: These clamps are 100% compatible with both Shimano and Campagnolo front derailleurs. Also, the 28.6mm clamp isn't made by Shimano. Shimano doesn't manufacture a 28.6mm clamp. Rather, it's made by the highly regarded company, Problem Solvers.

As advertised

  • Familiarity: I've used it several times

Works as it should without issue, at a great low price. Quality product for the money.

No fuss.

    Easy installation and adjustment. Just flat out works.

    Simple, durable

    • Familiarity: I've put it through the wringer

    Again, this will sound silly; but this just works. I have no complaints or anything negative to say. They're just awesome.

    My bike frame is a plain TI without any paint. Would it fit well since it is a case of metal on metal? I afraid it would (somehow) slip. Or, do you have any suggestion?

    Has worked well on my Merlin ti for decades.

    Unanswered Question

    Is there any reason this wouldn't work with a SRAM Apex front derailleur?

    Quick fix for getting your braze-on to a clamp on frameset. Nothing flashy here, it does the job well. Secure, sturdy, cheap.
