As a couple have said, you really have to ride one, I managed to ride a speshi carve or crave? at Cannock a few months back and loved it. Im a short arse 5ft5 at most 30″ inside leg, after the demo day I went and ordered a Canyon: Grand Canyon 6.9 and its an immense bike, the only reason I didn’t get the speshi was travel the small frames only come with 80mm and I know I need/want 100mm at least.
The Canyon is perfect for Cannock and if your a rider that keeps the tyres to the ground which is pretty much how I ride. The fit is perfect and well ive only had 2 rides out so far, taking the canyon for another blast tomorrow. Should of said my 29er is a small frame, and you can tell looking at it, but the front end is higher than my speshi camber 26er which is a medium but that helps with the fit.
Before I looked at the canyon I looked at the boardman team pro 29er but the TT was a little too long, the canyon is probably the first bike I’ve had that actually fits. If you want an xs in the canyon they come with 650b wheels not the 29ers.
People mock but until you ride one then you know if you want one or not, 29ers have come a long way in the last 4 years, geometry and spec’s are loads better than 4 years ago.
