    Is that a presta valve then, or just a schrader that shares that feature with one?

      Speaking of the tube itself, I've been wondering a bit about getting a spare as I start doing longer distances on the 36er.

      What I haven't figured out is how many miles of walk-out compare to carrying around the necessary tools and supplies and hand-pumping a 36er from nothing with a portable pump.

      And on the tube itself, how often is replacing the tube going to be a noticeable win over field patching with a tiny kit? Anything near the valve, and presumably any large tear, but that would probably call the tire into question, too.

      I've hear rumors like needing three extra large tire levers; realistically what would one need to carry?

      Stopped next to a guy on the roughly paved trail changing a road bike tire, his comment was he'd never had a flat on his mountain bike, but they were a common frustration on a road bike. Presumably we get the large tire benefit and then some.

          Successfully installed this tube on my Geared 36er (following bouin-bouin's choice), it is 168gm, who can say less?
          It fitted well the King George tire.
          My previous tube was a 220 gm schlwalbe 29er tube, and since the Schlumpf hub makes the wheel heavy, I appreciate this 50gm lighter tube, I'm pretty sure I felt some difference during my last ride. (you know, the one I crashed at 17 mph because of a accidental downshift )
          - Geared kh36 + Nightrider Lite + Kh Tbar + HS33
          - Qu-ax 36" + nightrider +Q-handle+ cable rim brake
          - kh 29" + knard 29x3+ kh Tbar + HS33
          - Qu-ax trial 19"
          -24"&26" wheels and forks and spare stuffs.

            I don't have a 29" tube in my 36. I have a 36" Foss tube. Makes an amazing difference to weight, comfort and response. I also have a Foss tube in my 29. Highly recommended. (I haven't checked, but I'm assuming they're still available.)

              The lezyne floor drive HV or HVG is my weapon of choice for unicycles. They also sell a high pressure version that is extremely light but it doesn't pump nearly as fast. Ditch the gauge (which really isn't useful below 40 psi anyway) for extra weight savings. It's a very comfy pump and can get a 36er tire back up and running reasonably quick. I carry it for my fat tire too. (weight is around 200g for the high volume, and 150g for the high pressure with no gauge)
