I'm riding the 4S 55.5 & ideally need to get my hand position back 5cm & down 2cm which is just not really possible and has not been advised by the fitter - which is why I'm interested in other do-it-all (read: I want it all) framesets.
100mm/-6 on there & 3T Ergo bars which are apparently notorious for being longer reach than stated. Loads of spacers, at a guess 40mm. So 3cm back and 2cm down would be possible, followed by about 1cm back with different bars.
I could also try an 80mm stem, 2cm down and different bars.

Back on topic, just spotted the new PX London Road SL but it's a bit porky and might not support Di2..
