i am contemplating the idea of putting track dropouts on an old cannondale 2.8/3.0 criterium road frame. i will not be doing this myself; a skilled expert will be sought, iff the answers to the following questions render this idea feasible.
does the post-reweld loss-of-strength of age hardened/heat treated aluminum make this a bad idea? or will the new dropout areas be strong enough for moderate-aggressive on-road riding?
assuming loss-of-strength is not so severe as to render the frame completely useless, how much should one expect to pay for a professional-quality job?
