    After a long time deliberating , bit the bullet and fitted the OUTEX tubeless conversion kit to my spoke wheels.

    Easy and worked well (well they haven't lost any pressure after 5 days), thought I'd just post up a positive recommendation.

    The only thing I had to do extra to the instructions was treat a fair bit of rust (chrome steel rims) that had developed under the rim tape. Obviously water entering through the spoke holes. OUTEX has a video where they just grind the rust away and install the tape over it. I made the decision right or wrong, to treat and seal the rust first (sandblast, chemically clean, and 2 coats of two-part marine grade epoxy primer). Treated the whole 'well' between the bead shoulders. In the process made sure the nipples had a good seal of paint as extra leak protection.

    Anyhow, for what its worth, seems a good easy to apply product that worked as advertised.

    P.S. Why get rid of the tubes?? Every day ride was a gamble that I didn't get a flat. Extended trips required extra gear to remove wheels, and weight of a spare tube in the bag. Plus got rid of 3/4 Kilo of un-sprung weight out of each wheel.

    I went with Outex too. There are a half dozen "cheap" alternatives out there and it seems riders are happy with those too. I spent the extra $ for a purpose specific product backed by Japanese racing technology R&D. Not looking back.

    it's just heavy tape over the spokes, not a big deal.

    the 3m stuff, silicon+gorilla, outex, or whatever works fine.

    Same reason I went with the Outex, doing 200 kph I don't want any doubts in the back of my mind. No way in the world would I be comfortable with dobs of silicone and duct tape.

    The product is more than just 'heavy tape'. Yes it is tape (two types), but clearly it a well thought out special type of product. Both tapes are very soft and workable. That endless people have used it without a problem is what swayed me in this direction. Any problems I found when researching the product were all poor application by people with seemingly little mechanical aptitude.

    I actually didn't think it was expensive. By the time I would have bought the bits and pieces there wouldn't have been that much difference. Just the two chrome valve stems that come in the kit alone would cost me A$12. A roll of the 3M tape that people use would cost me $50. The one liter of marine two part epoxy primer I used to treat the rust cost nearly as much as the Outex kit.

    I thought there was some magic in the outex "system" (everything from an inner tube to a roll of tape is now called a "system" by folks nowadays) until I saw them side by side. the 3m tape is thicker, almost a gel, with a backing so thick it's just silly. application of the outex tape be 3m take us the same, just get it close to the wheel and it holds like a pitbull bite. mess up and you get to reapply the whole wheel. is good to have a heat gun to soften the adhesive, and then it's still a job.

    I bought 10m of tape for about $35 shipped. it's so cheap I used it to make anti abrasion pads for the frame. I bet you could hold a door onto a 50's era Cadillac with this stuff!

    Is the valve stem that comes with the system special in some way? Would I still be able to use my TPMS sensors instead?

    I recently did a second wheel on my newer 800XC. I went with Outex again but didn't buy the kit, only the tape. Save some money that way. The kit valve is an ordinary 8mm so I bought a valve from NAPA, part# 90-426. The valve diameter works well with the hole diameter in the XC spoked rim. The hole in many MC spoked rims is for 8mm, a smaller diameter than some alloy rims with 10.5mm valve stems. The hole is sized for a tube.

    With the Outex "system" you cut a hole in the tape where the valve goes through. The Outex sealant tape is wicked sticky. The protective membrane is pretty tough. If your TPMS sensor mounts by compressing two grommets, I don't see why you couldn't use it. Watch Outex Video for more insight.

    Was the handling improved as they said? The ebay ads say something like it not being just about unsprung weight, but a stiffer connection between the tire and wheel. No idea if that's true or not.

    Way back when, I bought a set of Lester wheels for my 90S because supposedly they were able to be run tubeless. Didn't work out. Coming home one night the tire popped off. After I called Lester they told me that I could not run these wheels tubeless because the rim profile was not made for that. I'd be real careful converting tube type rims to tubeless.

    I installed it on the front and rear rims of my 701 enduro last month. Put on a set Pirelli MT90AT tires. Was able to get the front tire to seal, but could not get the rear tire to "pop" on the rim. Had to use a tube instead and just used the Outex as a rim protector as I was leaving the next day.

    Did 1400 miles (tarmac) in 3 days on the bike with no problems. A month and half later the pressure is the same in the front tire, unlike the back tire that I have topped off at least 3 times.

    I have the Outex system installed on the rear of my 990ADV (stock rim) for over 3 years and no problems at all. Plus it hardly ever needs to be topped off.

    Check out Italian company BARTUBELESS for EU riders. They put some polymer stuff around the rim, test all... I did my spoked r nine t wheels and I was very pleased with the quality and final result. 3 years later and 3 sets of tires, no problem.
    IMHO much more safer and secure than tape.

    There's the tape. There's the spoke nipple covers. And there's a process to follow that includes cleaning and prepping the rim and installing the products. I'm a systems engineer and that's a system. Buying some poly tape at Lowe's and taking great care during the cleaning and installation is also a system. It's just your own system. Systems don't have to be complicated or have a lot of moving parts. A system is just a specific way of applying a solution to a problem. A proven system is just one that's been made better through testing and improvement.

    Wondering what kind of pressures you can run using a tape-sealed rim, regardless of the 'system.' The tubliss lets you get very low pressures for off road but it is actively clamping the tire to the rim. If you went very low with this system it seems like you could start burping. I don't know if it's possible to spin a rim inside a tire but with a heavy, powerful bike, like a 701, it might be possible if running low pressure. I've got a 701 and would like to go to a tubliss or even this. Be nice to air down for off road.

    Road racers will spin a tire on a rim on both fr and rear from both acceleration and fierce braking forces. Drag racers and dirt cars will install screws in the rims that poke into the tire beads to stop tire rotation on the rims. I too question the safety of running tubeless on rims that were.nt designed to fit tubeless tires. Was always told that the shape of the bead was different. Probably BS from some safetycrat.

    nah man, its just tape.

    yes, burping is a real issue around 15psi and lower. i experimented with pressures after i did mine, if you run >25psi is pretty hard to burp it without a considerable hit from the side, but a simple root contact at 15 and lower means quick loss.

    you'll spin the tire vs rim around 10-13 psi without a rim lock, if you're using a non safety bead rim.

    safety bead rims take more power to spin, but i don't know how much, as my street wheels stay at 25 psi or so
