I like them. They seem nice, light and uncluttered.
I hate the graphics on a lot of bikes these days, they just look a mess! There's something 'minimalist' about Canyons that appeals to me.
I'm considering one for when I eventually get the money together, but I'd really like to try one first, or at least see one.
Do they have a scheme whereby you can send the thing back if you just don't get on with it? They get good reviews though.
I think, of the two, I prefer the Ultimate.
