I got this bike in 2013 with original Di2 20 speed but upgraded last year the whole group to Di2 Dura Ace 22 speed at BYX. Everything is Dura Ace (wheels are C24s, pedals, brakes, etc.). Handlebar and seat post are carbon (and I include 2 extra seat posts and a very nice extra saddle), pedals are less than one year old, etc. Sam at BYX knows the history of this bike -- was serviced there. Will include many extras (like many high-end lights, tyres and tubes, break pads, extra battery, etc.) that don't fit my current bike. I think the size is 55 but I am not 100% sure (I am 1.84).
