Boardman were a bit odd with years and over lapped, its a 2010/2011 bike. For some reason their new bikes came out around Spring/Summer but for road bikes that makes perfect sense!.
To be honest, You wont find many better bikes for the money he’s asking and you would probably get it for around £500. They are great bikes, I had a 2008/2009 Road Team and the frame was fantastic, really stiff but comfortable and the complete bike was around 19 lbs, for a alu frame running Fulrcum 7 wheels, thats not too bad. I really regret selling it to be honest.
Sram Force is a very reliable, light and positive shifting groupset and better than Shimano 105, probably on a par with Shimano Ultegra in my opinion, my Boardman had Ultegra and I prefer the Sram Force I am running on my new road bike. Aksiums are entry level aftermarket wheels but are a nice upgrade as is the carbon post.
