its a 2010 model i found it on ebay yeah its got a sora rear derailer the rest of the drive train is kinda cheap but it feels pretty solid i got it today and have rode it 11miles so far it feels more expensive than a 400 bike its also my first bike with a carbon fork i kinda like it takes some of the bump outta the ride i think im gonna get some new cranks and front derailer and a carbon seatpost here in a few months
