Quick question for anyone with a Canyon Endurance Large

I'm looking at the Canyon site as ideally I like a 55cm top tube with my longer torso which would put me into a large. The geometry on the pics state a seat tube of 55.5cm top tube which would be fine as I'm 6ft and usually use a 12cm stem.

My query is the seat tube on the canyon site is measure from centre to the top of the seat tube at 56.5 which puts me back into a medium! obviously the measurement is taking into account a lot of seat tube. Can anyone give me a measurement for the seat tube on a large centre to centre of the seat tube? it looks a good few cm extra so guessing more like 52 is measure in the traditional way.

Cheers!
