I personally like the Kilo as a framset. That being said, is it worth investing more into the frameset than it is worth. If it were me, I would be looking for a quality road bike frameset for a conversion or saving up for a Wabi. Frameset/weight/geometry will make a bigger difference in my opionion.

Good luck, but done spend too much scrilla on upgrades for a frame you say you are going to get rid of. A wheelset or frame will be better money spent.
