do you want a track frame or road designed frame or does it matter to you? do you want a brake or brakes? does the weight of the frameset matter to you? check out the gearing to determine if you will need to replace the cog, no big deal, or chainring, bigger deal, or both. there's a love fest around here for the BD Kilo TT as being great value for $. I know nothing about them. I have a Wabi which is a road geo with track dropouts and high bottom bracket for fixed gear. I did a century on it Saturday as comfortable or no more uncomfortable as on one of my geared road bikes.
