OK so I'm looking to buy my first track bike. How does the sizing compare to road bike sizing? Is the seat tube shorter due to BB height? For ref i ride a 54-56 road bike.

Thank you as always for your advice.

BTW anyone have a cheap track frame they want to unload

seat tube is the same, you'll just be a little higher off the ground. you'll lose some stand over. some folks go small for track bikes on the road so you have a little more control over whipping the frame around.
