Caliwild, Doesn't matter who does the work as long as it's done. The panto'd bits are hard to find, perhaps more scarce than the bikes themselves. I can't give any advice on your last sentence, but this is where the bike shop should flex their knowledge. You can let those on this forum know what the choices that you are given for a critique as many are OCD period correct.

Mine, actually it's my son's French fit project, was only available as a frame set and by order only due to it's 64 cm size. As such it's a mixed brand gruppo.
