Post too long, ha! Recently build an MX Leader 60cm. Found that this Frame had a shorter bb to stem dimension, horizontally, compared to my 57cm Pinarello. Zero offset stem was needed, obviously. Stem .5cm shorter. The overall length of the frame is longer, which leaves the rear wheel(which is tight to the seat tube) set back in relation to my saddle. The frame handles beautifully. However, riding w/o hands requires more speed, as I am more forward in relation to the rear axle.
