Hmm..that'd be about 200 miles to cycle to. I know OneMoreSolo has done it but I think I'd have to wait until more summery weather before I attempt it
Do you work at a bike place that has some Canyons on display or something? It's not impossible that I'll be on London in the near future so I could actually pop along to Kingston on Thames.
edit2: Or do you just mean having a look at yours once you get it?
Canyon UK are based in Kingston and I believe they do test rides, but give them a ring to find out.
Alternatively you could try mine. Size 56 ok?
