I've commuted on the Kilo off and on over the last 2 years. It was my only bike for a while so I just did everything with it, but now I am looking for something a little more commute friendly. The Kilo has "track-inspired" geometry which I find slightly too aggressive (shorter headtube, steeper angles, higher BB/CoG, short chainstay), especially for long miles/heavy cargo loads (backpack/messenger bag). I didn't have problems with fitting fat tires (700x28) or fenders (SKS Raceblades), but I do notice the nuances in the geometry. I'm now looking for something more upright and with longer chainstays to accommodate a rear rack and panniers.
