This bike has a pretty long TT, probably longer than I should have, but it's a good ride, very supple and responsive. I already have a "7" shaped stem on it, 7 or 8 cm, so it would be hard to go much shorter. I think I need it to be about between 2 and 4 cm closer, so I should be able to accomplish that going from a V-O rando bar to a true compact, but we'll see. I may also convert the stem to a quill mast topped by a threadless stem. That has worked well on a different bike faced with a reach tuning task
But with 650b, relatively low trail, 747 standard tubing and the ability to host 38 mm and 42 mm tires, I still have a few variables to play with.
