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?
