The similarities are uncanny. I too ride 56 ctc road bikes, am almost 6' tall, good looking, have a luscious (albeit 'merican) accent and I own a Chevy 4x4. Hey three out of four ain't bad. Anyway, I just took a poll of my track bikes and six of them are 56. The other one, a Signature model Steelman is a 58. I once dated a woman taller than I am... But I digress. Ted, et al will probably point out that the bottom bracket on a typical track frame is higher, so you might want to consider a track frame slightly smaller than your road bike. But if "stand over" is one of your concerns, you probably shouldn't be riding a track bike anyway.
