I purchased my S40 back in October with the view of it being a bike to commute on and also being able to handle hilly brevets. Am pleased to say that with not a lot of tinkering I'm running a 40/23 chain set and 11-46 cassette. All works and shifts well.
For the rear cassette I'm using the Ultegra Shadow rear mech with a roadlink, and for the front mech set up it's a standard Ultegra with a Wickwerts braze on adaptor.
With the chainset I had too do a little bit of fettling but not much, the gap between the two chainrings was causing the chain to fall down in between them when shifting. The solution was simple, some washers from the local hardware store placed outboard between the crankarm spider and 40 chainring thus pushing the chainring in by a couple of mm - problem solved.
Have been using the S40 on the Tacx Neo with Zwift and also the Tacx training software to simulate grads of up to 20%, I'm pleased to say that even with a 23*32 set up power was well within threshold and cadence was nice and high in the high 80's, low 90's. Having just fitted the 11-46 cassette an eager to get out and tackle some serious hills but it's currently snowing here in the UK. Have got a hilly audax ride in a couple of weeks and have got a hilly 50km route set up for next weekend which I'll be riding if the weather holds out and will report back then.
This post is really just to say that the set up can be done, even in large - large, see below:-
