Any thoughts on preferences of Duro or Nokian Tubes in a NOkian 24 x 3.0 tire?
I ride a lot of hard pack single track with small rocks imbedded in the trail that I just ride over or around if they are to big. I like to hop when possible, but that is usually less than 10".
The Duro is heavier and thicker, but does it effect performance when climbing or micro adjusting tight areas of the trail?

Gee whizz, when will your Muni be finished? We have been waiting eagerly in antipation for the pics of your Uni and the test ride!
Sorry, we have no idea about inner tubes.
RE: Duro or Nokian Tube hmmm?
Hey Rod,
I rode around with a Nokian tube no problems for a few months. That was
until I weighed it and found it to be a couple of hundred g heavier than a
standard 24" tube.
Taking weight off the outer circumference of a wheel is a big boon to just
about all styles of riding. Not only does it make the wheel that bit lighter
it also means it’s easier to accelerate / decelerate. One change later and I
noticed an improvement in responsiveness in the wheel with the lighter tube
in it and no problems doing the same moves on my uni: 3’ drops, gaps etc.
The Gaz will have helped preserve the tube as well though.
I think the DH tubes only really come in to their own when your doing really
aggressive riding with big drops and gaps where the stress and strain make
pinch flats more likely. Your choice of tyre also helps reduce the chances
of catching a flat as most of the serious DH tyres are designed with this in
mind. My advice would be to stay with a normal tube and save the DH type for
long aggressive rides where you really don’t want to flat.
Cheers,
Neil

Great info. How much pressure do you run the non-downhill tube at, Neil? I’v been riding my Gazz soft- what a difference in sand!- but feel it on the rim when droping on rock or concrete. I suppose I might want to harden a lighter tube?

tubes
i like the IRC torque tube.its got the all metal theaded shrader valve.
RE: Duro or Nokian Tube hmmm?
I’m usually running around 18 PSI with the Gaz. That’s not really high
enough for drops over 18" though… based on my weight that is (c. 160lbs).
A DH tube will reduce your chances of a pinch flat compared to a normal one
at the same psi. So I guess you would have to run said normal one at a
slightly higher psi to get a similar pinch flat resistance as a DH tube. But
then, if you’re having to do that to stop flats all the time, you’re
probably better of with the DH tube anyway. Dunno really - I’m thinking from
the hip here 
My riding doesn’t seem to warrant a big thick tube so I’m
happy to run with what I’ve got I guess.
Cheers,
Neil

Neil,
I read your response several times, but I was a little confused.
Below is your quote:
I rode around with a Nokian tube no problems for a few months. That was
until I weighed it and found it to be a couple of hundred g heavier than a
standard 24" tube.
I thought the nokian tube was the standard that fit the Gazz 3.0. and that was the only lighter weight tube that fit the gazz. Can a regular no name 24" tube fill that big void?
Also, is the DH tube the same as a Duro tube that others have referred to? I took off my 2.6 gazz and found a Duro tube in it. I mounted the new gazz 3.0 without the tube because I didn’t have it and I had to order it. Mark at unicycle.com said the 2.6 Duro wouldn’t fill out the tire as much as the Nokian tube size 2.3 - 3.0.
Unimatrix 0-1,
I sent my wheel and tire to the frame builder on MOnday and he will get it Monday, may 12, at the latest. He is in Evansville and I am in Los Angeles. Work should begin next week 5/ 12. I definately will post pix when it is all finished, but it will be a while. Don’t expect anything new fangled, but it should be a looker.

Finding the pieces.
A thinner tube will have more “cush” and will flow better over rocks, sticks, roots, etc. The ride will be softer. Less weight in the wheel makes it slightly easier to pedal. Unfortunately, thin tubes are more susceptible to pinch flats.
For the type of riding you describe a thin tube should work just fine for you.
Unfortunately thin tubes don’t work for me. I started out using a thin tube in my 3" Gazz and ended up getting a pinch flat. The roots and logs that I ride over and jump on can cause the tire to bottom out on the rim. I now use a really heavy Intense DH tube and have not had any more pinch flats. Flats put a damper on an otherwise fun ride so I have chosen to put up with the extra weight to avoid pinch flats.
The Intense DH tube is heavy. It’s about one pound of rubber. The Nokian tube is noticeably lighter. You will feel the difference when riding with the lighter tube. I just wish I could get away with using a lighter tube cause a lighter tube feels so much better.

I was a little confused when writing - and trying to bring a network back to
life after it died for not apparent reason.

A regular 24" tube will expand to fill a Gaz. Regular tubes will have a size
rating (e.g. 24x2.125) but that’s only a recommendation. With a good tyre,
rim and running at a psi that doesn’t bottom out you can avoid pinch flats
under most circumstances… it’s worked for me so far anyway.

I don’t know about the Duro tubes I’m afraid. If the Duro tube from your
2.6" is a thicker DH one then it might well resist expanding to fill a 3"
tyre slightly more than a thinner normal one would.
