Shimano Dura Ace Di2
The snappily titled Cube Litening Super HPC Di2 – we’ll just call in the Cube, if that’s alright with you – is one of those bikes that’ll have even non-biking mates whistling through their teeth and asking how much it weighs, how much it costs, and whether they can have a go. The answers are 15.2lb (6.92kg), £5900, and no. It’s a full carbon race bike that comes fitted with top of the range everything, including Shimano’s Di2 electronic shifting, and it goes like stink.
Di2 is Shimano's new, flagship groupset. Combining Dura Ace 7900 ergonomics with the performance of an electronic shifting mechanism sets this apart. Di2 is the best groupset that I have ever ridden, but then for this money so it should be.
