Hi Guys,

I'm a tall rider and have found myself needing an extra little bit of height since moving from platform pedals to clipless.

I'm 6'5" and have a XXL bike with a 873 standover and 620mm top tube and I have a 400mm seatpost extended to the limit (in fact about 5mm past the limit).

I noticed that thomson make a 410mm post and was going to get one of those...then I saw they come in a straight and a setback. I'd like to go for the setback but had one question:

When they're measured flat (top to bottom with a straight ruler or something) would they both be exactly the same height or would the setback be a little shorter due to the slight angle at the top?
