Cheers for that. Defo 2008 (manufactured in 2007 going by the frame no) then.
Mates one is a 2007. Will check his frame no next time he has it at work to see if there's an '06' in there somewhere.
Looks like I just need to get busy cleaning that seattube out! Finished the brazing on it today (I hope) so it'll be getting it's last soak and then I'll get the reamer out.
