    best is to have tubeless, easy fix and can be run low pressure without pinchflats

    Oh man I would love to have tubeless :nod I'm going to put the TUBliss system on the front but unfortunately, they don't make one for anything larger than 2.15 on the rear.

    ...not to mention, the tire won't roll around on the rim with Tubliss - being that the high-pressure inner liner locks the bead onto the rim.

    I'm planning on putting a Tubliss on the front - anybody know how they hold up on the pavement & high speeds?

    I want to compliment the tubeless rear on this crazy set of Woody's wheels I got today :wink:

    If you use a tire with a thick side wall, the 2.15" Tubliss should be ok on a 2.5" rim. There are a couple of people who run them on their SEs with stock rims, including Crankshaft.

    I have a new 690R. It came with MT21's. I've only done about 750 miles so far and most on pavement, but I probably have 150 on dirt and some sloppy mud. Pretty good tire! The only negative is that they are really noisy on the pavement above 60mph. Never heard such a shriek...

    Hope they last longer than the TKC tires I used on my old 950. BTW, those were noisy too.

    I don't know how different the Tubliss system is, but my son raced the Mexican 1000 last month aboard a new KTM 350 with the Michelin Bib Mousse tube replacement system. The first stage had a dry lakes section where he was pinned in the mid 90's for a long time. The rear tire totally disintegrated! Might not have had enough lube. The system was new to the team but they had no more problems after that and there were lots times they were pinned for long stretches. Maybe Tubliss doesn't suffer the high speed overheating issue?

    Might want to PM Neduro here. He knows everything about these non-tube systems for off road racing. He's used them all from Michigan to Dakar. He probably has a helpful opinion.

    Not sure how well a front Tubliss would hold up on a big bike or how it would affect high speed pavement? I guess worst case you could always put in a tube when you needed to. The Bib moose from what I understand is difficult to balance and has heat issues running on pavement at speed, but I havent tried on myself. Front tubes are easy enough to change out and since you will have to carry one anyway...........

    I ran Woodys sealed spokes on the rear for quite a while. It was really nice when I picked up a nail. However tire life was a little shorter because I couldnt run to less than about 1/8" tread depth as they would develop numerous small cracks on the carcass that would leak air. Slowly at first, then after a while there were so many that I couldnt keep air in it. This was with both tube type and tubeless type tires, didnt seem to matter.

    So at one point when I needed to get more life out of my rear tire, in my infinite wisdom I decided to put in a can a fix a flat..........that promtly ate through the material used to seal the spoke nipples. Goodbye tubeless, it was nice while it lasted. :lol3

    cjracer has been using them at highway speeds without any issues.

    I've not heard of the TUBliss running hot. The way they are designed, there would be no friction between the high pressure tub and the tire. May need to do some investigating to see just how they hold up on a 2.5 rim

    Bib mousse and Tubliss have absolutely nothing in common, except that they both replace a tube.

    There is lots less friction with Tubliss than for example with a heavy duty tube or mousse, so there will not be any issues with heat. However they do tend to loose a small amount of air over time, so you should check the pressure of the liner regularly. You will need a high pressure pump for it (100 psi capable at least), not a normal high volume pump like most people will carry. There are some quality mountain bike pumps that can be switched between both.

    I hate it when I'm daydreaming and get woke up like that :lol3 That was a hard it! Did you look back to see what fell off and if you needed it? :rofl

    Sense the TUBliss seals the whole tire by pinching it to the rim I wonder if a hit like that would break the seal.

    I was just zoning out, not paying attention of course, and I saw it just in time to get on the pegs and flick the throttle. I was in too high a gear to loft the wheel to the other side. :eek1 I almost lost it. Notice the conveniently located tire shop? :lol3

    The 1.85 Excel superlaced wheel had a pretty good ding, but I think an A60 would have been unfazed, maybe. Would be interesting to see what it would have done to the Tubliss system.
