I read a review of the Colnago that claims that, due to the geometry of Colnago bikes, one should buy a frame a size too small for optimal fit. There is a nice Dream Pista frame on E-bay, but the size is a 55cm, the largest size I can fit. (52-54 is what I ride normally). Will this bike actually fit more like a 56-58cm track bike? No need to sell off all of my earthly belongings for a bike that won't fit! Any help would be great, thanks.
