I was tempted by a Cube a couple of years ago but the lbs was owned by a complete arrogant ignorant twat and after a bit of further research I heard (at the time, don't know about know) that Cube had serious issues when it came to customer service/ timely replacement if anything was found to be wrong. In the end I bought a Rose, finding then to be slightly better specced and one hell of a lot lighter £ for £, they also allow customisation at build.
The peloton SL posted by toeknee looks a nice bike but having said that for an extra £90 you could get one of
these with full Ultegra and over 1KG lighter.
