"With long slot horizontals, a "good" builder's chainstay length would be established to meet design spec from BB center to the axle centerline at a point between 6 to 9mm in front of the rear derailleur hanger eye as that is where the axle center "should" be relative to the hanger eye to ensure the best shifting with modern components. YMMV with old components or not so good builders.... :)
Don, Of course a properly designed vertical or semivertical dropout takes the guesswork out of all this, as they yield only one wheel position, Amen!, but say, on a frame with 8cm drop and 42 cm chianstay length, where should the favored axle center be on a Campy 1010B dropout ? Starck, Joe P.S. I assume we're all measuring chainstay length, side view, parallel to the ground, not, parallel to the chainstay, hence, your favored 6-9mm distance would be measured the same way forward of the derailer hanger eye, eh -- or not?
