Ok, I'll go out on a limb here so somebody correct me if I'm wrong but I have the following specs for the seat tube thickness:
SL 0.6/0.9
Aelle 0.8
So if the outside diameters are the same and SL uses a 27.2 and assuming that it's the 0.6 value that at the top of the tube where the post goes in, then an Aelle frame should use 27.0.
That make sense to anybody?
edit: Just another thought - the standard O.D. of the seatpost is 28.6mm - so if, for an SL frame, we subtract 1.2mm (0.6mm x 2) then we get 27.4. That would mean the seat post should be 0.2mm smaller than the measured I.D. of the tube which again would point to a 27.0mm seat post size for you Aelle frame.
I'll shut up now so somebody can tell me I'm all wet.
