Ft. Der. on a Custom Frame: Clamp-on or Braze-on?(5 posts)

Ft. Der. on a Custom Frame: Clamp-on or Braze-on?Val_Garou

If you were having a custom frame built up, would you spec a clamp-on front derailleur or a hanger and why? Or does it not matter at all? Aluminum frame, if that matters to anyone.

All opinions appreciated!

I'd go for a braze-on fitting. I don't know if there are any particular advantages, I just think it looks better than a clamp.

A clamp usually gives more latitude if considering smaller chainrings.
You can also vary the angle more.dzrider

Sometimes turning the derailleur so the cage sits at a slightly different angle relative to the rings can make a huge improvement in shifting. While you can't screw up as badly with a braze-on, the clamp-on will always allow you to find the best possible angle.

On a steel frame, if you add in the weight of the braze on "tab", you only save about 10 grams over a clamp on hanger.
On an Aluminum frame the difference will be less because most tabs are bolted on.
