Not my bike (possibly will be) but these single ring set-ups seem to be gaining a lot of traction in the market. Been researching a number of bikes of this ilk - Cannondale Synapse SE Disc, Giant TCX Advanced SX and Whyte Wessex One
Had a short ride on one of these a week or so back - with 44T + 10-42 which gives a pretty wide range. Having a longer test ride on Friday if the weather permits.
First impressions, SRAM double-tap is really intuitive (have tried it before). One ring seems to be less of a faff than two. The big jumps (I guess 'big' is relative to what you are used to) in the cassette range occur in the steep-hill bail out gears and there is zero chain slap on rough roads due to the RD clutch mechanism. Will see how it works out with some hillier riding on Friday.
