If your frame has a braze tab on the downtube,you HAVE to use a braze on. otherwise,you can use a clamp type or a braze on with an adapter clamp and it makes no difference. If you have a 13/8" seattube,and need a shimano FD is has to be a braze on with a clamp adapter, and very often if you order a shimano FD for a 11/4" seeattube that is also what you will get,even tho shimano does offer a clamp type for that diameter.Campy gives more choices in clamp diameter. Shimano mtb FD are available in all 3 seattube diameters as clamp type and no braze on.

A braze on dérailleur on average will be a few grams lighter than a clamp on. (This is slightly off-set of course by the 'tab' the braze on dérailleur attach's to).😄

The clamp-on dérailleur offers a greater range of adjustment to accommodate a larger front chain-ring.

It's just a matter of frame design and fit. Oh, I suppose there's a 0.2% weight increase with clamps vs. braze-ons, and maybe a 0.6% increase with braze-on/clamp-adapter combos, but in the end, you buy on the basis of what your frame requires, period.

No sweat. Inquire with the frame maker or your favorite local wrench, if you've got doubts about what your bike needs. Good luck.
