    Clamp-on v. braze-on front derailleur

    I'm sort of embarrassed to ask this, but can I simply remove the clamp from a clamp-on derailleur and mount it to a frame with a braze-on front derailleur tab? Is there a special nut or washer required?

    Thanks in advance.

    Or phrased the other way, if you can, then yes.

    and no to the last question
    There's sometimes a buggy.
    How many drivers does a buggy have?

    One.

    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.

    A true clamp-on will have the clamp integrated with the derailleur.

    A braze-on can use an adapter when the frame itself does not have a braze-on mount

    If your front derailleur is like the first picture, then the answer is no. If your front derailleur is mounted on something like the second picture, then the answer is yes.

    I have two bikes with DA 7800 front derailleurs - one braze-on and one clamp-on. I'm 99% sure the clamp-on is a braze-on plus non-integrated Shimano clamp.

    You're confused. If the "other" derailleur is attached to a separate clamp as you describe then it is simply a braze-on derailleur used on a frame that doesn't have a brazed on mount, so they used the adapter clamp.

    I was able to find a badly worn braze on chorus frt. derailer and remove the braze on head. I was then able to remove the clamp from my clamp on derailer and replace that with the braze on head from the wore out derailer. It was the cage that was wore out, leaving the head in good shape.
    I don't know what kind of components you have, so this may or may not be able to be done to yours.

    Pg.34 has the exloded diagram, if I did this right.

    True that if you have two derailleurs, one braze on and one clamp on, you can disassemble them and swap parts around to do what you did. That is not what the OP is asking about.

    He wanted to know if he could use his clamp on by just taking off the clamp, or if he needed a special nut or washer. I told him how it could be done, with a little more than a nut or washer.
    The OP didn't say if it was a clamp on derailer or a braze on derailer with an adapter. I assumed that it was a clamp on derailer

    He asked a straight foreward question and I tried to give him an honest answer on how he could make it happen.
    I'm sorry if you were upset with that.

    Really, I'm not sorry.

    I'm not upset. I simply pointed out the OP's question was "can I simply remove the clamp from a clamp-on derailleur and mount it to a frame with a braze-on front derailleur tab?" I agreed with your explanation of a possible way to use some parts of derailleurs to make this work.

    This is why I always buy braze on derailleurs. I can swap them to any bike with the right clamp.
    Embrace the fact that everyone on these forums has their own unique desires, needs, experiences and environment so what works for you may not work for others.

    Same here. Plus you can more easily mount a chain watcher thingie.

    Oh, you'd have to be a special nut alright.

    New FDs are pretty inexpensive relative to the rest of the stuff we stick on bikes. I just bought a new one last time I had that problem and... I'll never buy a clamp on again as as result.
