front derailleur braze-on vs clamp?!?

[Davidm]

My bike has Shimano 105, and the frame has a braze-on that the front
derailleur attaches to, rather than the clamp around the seat tube. Now as
far as I can see, the 105 derailleur is the same on both braze-on and clamp
versions, but the differenceis whether it's supplied with our without the
clamp...is this correct?

And secondly, what's the opinion if getting a frame made - should I opt for
the braze-on and thus not have the rather ugly (IMHO of course) clamp and
extra weight, or is this limiting? If the braze-on suits Shimano will I
somehow be limited in choice in the future to easily swap to Campag etc?

Cheers

usually the clamp/brazeon is just a variable part. you can get adapters from the clamp to brazeon style, and Im guessing the other way too?

IMHO if you were going custom frame the clamp way would be better as it gives you more flexibility for vertical adjustment if in future you dabble with a triple crankset or one of the compact setups.
