Cool! That is something Jim could strap to his back to take on a trail ride.

He did say he'd ditched his hand pump, didn't he? And if he needs a boost up a long hill, just point the valve rearward, and open 'er up.
Hey Josh...question for you: is it OK to run tubeless on the front, but tubed on the rear? Or will that invoke some weird handling quirks? I want to put a wider tire on the front for better float through some of the many sand and gravel patches that we have here. If I don't hit those at a fast clip, I'm sunk....literally. I want to keep the existing Slant Six on the rear, but Kenda does not recommend sealant for that version (last year's), so can't go tubeless on the rear.
For a new front tire, as the Slant Six is working extremely well for me in our smooth hardpack terrain, and the new versions are now sealant-compatible, a 2.2 version of this tire is my first choice. Or a 2.2 in. Ignitor or Saguaro....we'll see. But since I will be pulling the non-sealant-compatible Slant Six off the front, I have an opportunity to try tubeless as replacement and see how it works. Just concerned that staying with a tubed tire on the back will not work well. Let me know what you think.... Thanks.
