I have it on the front of one bike; but it would be very slow for the rear. I've recently tried a Geax Gato on the front too and it seems faster and bigger for about the same weight - I think I'm liking it more.
I ran them front and rear with tubes on my fully rigid single speed 29er. I am also running them on my carbon 29'er with good success tubeless. They work well on sand.
I don't at this point want to read the entire thread. I had a look at the Panaracer website and don't see any reference to whether there is a 29" "tubeless ready" version of this tire. In fact the only 29" seems to have most of the technical features omitted. I'd like to try it but there doesn't seem to be a tire that works for me. Am I missing something?
The trouble with having an open mind is that people will insist on trying to put things in it.
