Yes, you want a "braze-on" front-derailleur. The mounting-bracket should be considered a part of the frame, not the derailleur. They are very, very specific to each and every single frame. Some have different types of mounting holes. The curvature is different depending upon the size of the seat-tube... etc. Always keep the bracket with the frame at all times. If you are getting the frame-painted, tape the bracket inside the BB-shell so it doesn't get lost. if you lose it, chances are very good that you won't be able to find another one and the frame is worthless.
