Just an FYI: it's the steerer that will have 5 spiral ridges in the inner base (usually visible if you remove the front wheel and turn the fork over) that indicates the fork (and implies the entire frame) was build with an SL or SP tubeset. If the frame is a later build it could also indicate an SLX, SPX or TSX tubeset, but those would also have similar "rifling" in the base of the 3 main tubes, for which you need to remove the BB unit and shine a light into the BB shell where the main tubes are brazed.
Typically the lower-cost tubesets (Aelle and Cromor) use a smooth steerer (no rifling in base), and Aelle usually has a 26.8 seatpost.
Cioccs have been built with all of the above tubing, maybe some combinations as well, I've even seen one re-badged ALAN aluminum frame and it's possible that the contractors briefly used Oria tubing for a few.
One last question: does it have the little "man on a bike" stamp on the rear brake bridge that would indicate a 10-speed Drive import?
