OK so taking everything in... second hand that fits better than new that doesnt... will this, then, in theory, be cheaper?
I realise that flat bars aren't suitable for the event, but completely missed that when I looked at the bike, which is embarrassing. I think I'd prefer to go for a more upmarket bike that was second hand than a brand new bike of the same cost, but I'm concerned I'm gonna make one of my signature spectacular-cock-ups...
