Now this does NOT include a bike with road geometry set-up as a singlespeed. i.e. Jamis Sputkik vs. Fuji Track Pro. The track bike 56 will have a higher top tube than the 56 road bike. Ride both and decide for yourself. As long as you have a comfortable distance over the top tube and your junk isn't resting on it you'll be fine.
