RE: tubliss?

Motocross Action Mag had a good write up on it.

RE: tubliss?

They are nice can change air pressure and run very low pressure. The very inside tube is high pressure. You can still get puncher I hit some garbage in the trail sliced my tire ...... never came off the rim on the why home. I could run tube in the tire of buy a new to use Tubliss.

Tu-Bliss is providing a set of their tu-bliss systems for the raffle, on front and one rear for FR 3, so maybe the lucky winner will do a write up for us here on the site!!!!!!!

I finally got around to fitting mine to the 650. I always have a problem spinning front tyres, but not rears. Dunno why, but maybe I'm hard on the brakes? My main interest was the bead locking.

They fit easy after drilling the bigger hole for the rim lock substitute. I put some Slime in as recommended and set the pressure to my usual 12-13. I found the front washed out a little easier, so bumped it to 14 psi. The Ultra HD tubes I normally run presumably added somewhat to sidewall stiffness. I also found evidence of Slime escaping at the lower pressure, and the pressure dropped off during a ride as a result, down to about 10. Set at 14 and handling is better, and no leaks. The ride compliance and feel is like at 11-12 with the big tube. No rim dings and if the tyre has spun I haven't noticed, so my objective achieved.

I also may have had some leaks due to not being able to get more than 100 psi out of my compressor for the bead lock tube. OTTOMH 110 is recommended. Might have to investigate a HP bicycle pump, but so far I'm happy.

Not sure if I'll get one for the back yet, we shall see. I'm a pensioner now, so have to watch my pennies.

Cheers

fwiw steve the little 12v 4wd compressors should do it

i use them to charge shocks, 190psi is possible.

just another one, on those little sheit box 4b pumps...i was using one that i got from autobarn & i hooked up my good compression tester gauge into the compression line of the 4b pump.
when the 4b pump said 125psi the compression tester gauge said just under 100 psi.
the packaging on the 4b pump said it was capable of pumping 300psi...what a load of b.s...don't be fooled like i was.
fwiw..yep i have to agree with steve on the tubliss,the tubes in the normal set up do hold the sidewalls up more.
probably have to run about another 4psi in for the same sidewall sag.
where the traction is greater,it will not be any advantage,cause the sidewalls will just fold under if you run lower pressures.
maybe on slippery surfaces where there isn't as much side pressures trying to fold the sidewalls under, you could run the same pressures as you do now with a tube(which will have a bigger footprint with the tubliss),for more traction & still not have to worry about pinching a tube...make sense?

I have thus far had excellent success with the Nuetech Tubliss system, both front and rear, through three tire changes. The main advantage for me has been the ability to run much lower tire air pressures without the constant fear of rim pinches. With tubed tires I found that I would have to run up to 20/15 psi, front and rear, to avoid rim pinching in higher speed rocky areas. I did suffer a puncture flat during my two week trip to Stanley, ID this past summer. A two minute trail-side repair with a 'plug' provided a permanent fix.

I got one of the cheap compressors from Aldi recently like Bushie suggested and it goes to 150 psi or more and now I can get the 110 psi in the Tubliss tube and its all good, no more leak evidence, ie no Slime escaped and air pressure held. I've settled on 13 psi as being equivalent to 11 psi with the 4 mm tube. Note that even at 11 psi I had no problems with pinch flats or dinged rims over the rocky terrain I mostly ride. I attribute this to my suspension setup (and 4 mm tubes). When the bike was new, and prior to springing and valving, I dinged a rim on my first ride with 14 psi.

In theory, with the less unsprung weight of the Tubliss system, suspension response should also be improved, and if you are really sensitive, you could add a click of compression and/or rebound to compensate for faster wheel speed. Personally I haven't noticed, but I am still learning to ride again after my knee reconstruction last year!

Hey Steve,
Did you get yours from Ballards or some other place?
