Hi and Welcome!

Im about your size and ive recently picked up a Leader 722ts in a 49. The geo is pretty decent but the top tube is a little on the long side. Started with a 100mm stem, felt a tiny bitstretched. Ive just ordered a 60mm cinelli ant to see how that feels, idk if its going to be to drastic of a change or not. I think i read some place that Leader made the frame to except shorter stems, or maybe that was just for the 725 idk.

Edit: Actually maybe not the best idea. Leader 722ts: 49cm tt is 525mm Kilo TT: 47cm tt is 513mm
