Hi does anyone know where I can buy a front derailleur braze on type bracket. Not the clamp type?

Thanks,
Stevie.

    just the bit of metal so you can get it brazed to your frame?

    try Argosracing. or any frame maker.

  • Yep, just the small piece of metal that attaches to the frame. I have a carbon frame with a clamp type at the mo. Not happy with this! Would rather rivet on a carrier type. Don't like the idea of clamping carbon tubing?

    Thanks,
    Stevie.

    You don't like the idea of clamping a carbon tube which will have been strengthened for the purpose, but are perfectly ok with drilling a couple of holes in it to pass rivets through?

    Don't do it. It's a bad idea.
  • The stresses involved in a clamp type bracket being tightened on a carbon frame are far greater than that of round holes. The stress cracks that can arise from overtightening a clamp around carbon can ruin a frame. Better to drill a couple of holes. Think about how the water cages are attached?

    Bottle cages are attached to specifically strengthened bosses built into the carbon fibre structure of the frame. Having holes in the frame is fine, if the frame's designed for them. Similarly, clamping a derailleur onto the frame is only a bad idea if the frame's not designed for it. If you're reasonably careful, that is, not ratcheting it tight with a metre long extension bar, the front derailleur clamp will not to any damage to your frame.
