I am planning on buying a Mercier Kilo TT as my first single speed & fixed gear bike. Since I am a noob, I don't really understand the sizing/ Kilo TT Geometry. I understand that I need a smaller frame since I am exactly 5 foot. But other than that, I am confused by stand over height, and whether or not I should get a 44cm, 47cm or 50cm bike. Any help would be greatly appreciated.
