I ordered in a couple of Surly Knard 29x3.0 tyres to experiment a little bit. First stage of that was to put one on a Velocity P35 rim and see what it would fit through. Turns out it just makes it in a Niner fork.
The ride is very nice, reminiscent of the fat front experiment of last year but a lot more nimble, agile and less hard work going uphill. Even after a short ride this afternoon I'm pretty excited to get some more miles on this set-up and start doing some drawings for a 29+ front and rear frame.
