Perhaps but it was clear that the Ti machine has a round tube with the axle having a through threading out the opposite
side from the mid drive cassette, where the steel machine had a square tube and according to mmatarella the axle threading
was not all the way through the square tube. So not only is the length of the axle different the Ti mount allows lock nuts on
the opposite side from the mid drive cassette where the steel tube axle bottoms out on the inside of the mount tube if I
understood mmatarella correctly.
