Thanks Carl - couple of comments/questions to follow up below.
Re fit, I'm looking like I could be on either a Large or X-Large (Medium-Near in both cases).
- Armpad stack is 680
- Armpad reach is 463
- Going a bit lower and longer for shorter events (so HIM and shorter).
- Saddle height (top of saddle) is 833
So it looks like saddle height is actually an issue here for me! A large with long post and 50mm offset looks like it will work (just - needs rails to top of saddle to be at least 20mm). I might get the 15mm offset to work if the saddle rails to saddle top were 40mm - any idea if this is the case with the Hilo saddles?
As I understand it the 50mm offset will put me further behind the BB (UCI style position) whereas I'm looking solely at tri's and am aiming for saddle tip about 25mm behind BB (and that's using a Hilo/noseless saddle). Can I achieve this with the 50mm offset seatpost?
So, does the above mean I "must" go to an X-Large?
(A Medium with the High-Far stem actually looked like a good option until I worked out that I couldn't get the seat height (even with the long 50mm offset post it maxes out at 792mm which means I need 41mm from rails to saddle top if I'm at absolute max extension) - any idea if a P1 build could fix that with a longer post or is it just that the frame and seat post combo is never going to get there?)
I know ST orthodoxy is go the larger frame and ride less "stuff" but I have seen you comment elsewhere that this applies less to the SC 9.X on the basis that the "stuff" is pretty integrated and aero. Hard to guess what would be stiffer (assuming I'm having to look between Large and an X-Large?) - an X-large frame with longer tubes or Large frame with more spacers.
Any thoughts?

3. Bonty don't do a disc wheel and so Trek don't give you any options for a rear disc as standard (best you can do is the Aeolus 9s). Am thinking of spec'ing the bike with the cheapest set of wheels possible and then getting a rear disc and race front wheel seperately. Any views on what disc (and/or front wheel) work best with the SC? It seems that the rear of the SC is reasonably well faired and so from what I can work out reading on here a flat disc might be the best way to go? Any recommendations (bearing in mind I'm clincher only - no tubs for me). EDIT - late thought, or should I look at getting a set of the Aeolus 7 or 9 and then getting a disc cover for the the rear wheel as a cover is supposed to be pretty close to equal with a disc in terms of aero or so I read ....
The latter.
Thanks - just trying to work out what disc cover would work as wheel builder say that the SC isn't suitable for theirs. I wonder though if that's with a low profile rim and whether a 70 or 90 rear would mean that the disc cover would fit as the "angle" starts from further back along the chainstay. Any experience or advice to offer here?
Cheers
