This is a little off topic, but someone did mention burping and crashing. I run 2Bliss tires tubeless on Roval wheels with the blue rim tape that came with the wheels. I weigh 153# and normally use 23-26psi in my tires. I love the grip this setup provides.

While I have never experienced burping, I'd love to hear from people who have with Roval wheels and 2bliss tires. Is burping common?

I live in goathead territory and went all last season (feb to present) with zero flats and zero maintenance besides pumping up to 28psi before hitting the trails. I used to get more goatheads in the valley floor than up in the mountains. So far I would say tubeless conversion (stock dt wheels and 2bliss eskar tires on 2010 enduro comp) is both more reliable and lighter than slime. I'll never go back to tubes unless they make it obsolete somehow.

Ps. My lbs mechanic said don't bother replacing old sealant until you notice leaks increasing, so the expiration date is definitely longer than a couple months. I've got a year on mine and still working well.

champion,,,, did you use rim strips on your dt wheels? I just converted my dt swiss wheels and just used the yellow tape. Haven't tested them yet

Interesting to see this measured. I've been running tubeless since 2004 and LOVE it. Recently got an Arch ZTR up front w/ yellow tape and that made it even easier. I did run tubes for a little while this December and had multiple flats...honestly, I can't imagine why I'd ever want to run tubes again. Or why I'd want to ride with people who do!!!? Too much waiting around while someone fixes that Goathead hole or pinchflat.

For those who have not ran tubeless, you will notice improved performance all around with less failure on the trail. Albeit it takes a bit more to install, that is back in your garage vs. out on the trail. There is a definite learning curve from installation, air pressure, repair if there is a problem on the trail and type of tire.

I typically will install a new tire with Stans and it operates fine until the tire needs replaced. Now this may be on the sketchy side for the life of the sealant, but it may also be relative to the type of terrain and locale where one rides.

The only weak link in the system based on my experiences is that using a standard tire your percentages of having an issue on the trail generally will go up.

Lots of good info here. Just converted to notubes. Excited about running them, good riding all winter now it is wet wet here in Calif.. I put captain and eskatar2 on dt swiss rims and used the stans yellow tape only and sealant. I hear about burping and I hope It dosen't happen on the trail. On the stans site there is a video about tubless comparison that is interesting. He takes a tire and makes it burp by pulling it over by hand,,, looks easy to do. I aired up my tires 30 psi back and 28 front and did the test,,, not even easy, so I think I'm good. I'm 190lbs dry.

Try to ride initially with higher pressure and reduce it every couple of rides to find your sweet spot.
My catastrophic burp happened when I did a low jump and when landed a sharp object (rock or stick) pushed against my Front tire side wall.
The tire burped all the air instantaneously and I crashed hard over the bars...
It was at low speed and a pretty shallow jump -maybe 1-2 ft.

I had my lbs do it for ten bucks a wheel. They replaced the yellow rim strips with stans tape cause they have it on a bulk roll. They insisted on replacing the rim strip and I trust these guys. The stans kit was like $70 or something so I just let them do it for me it was cheaper and they'll back up their work. I did run tubes for a bit first i think that helps mate the tire to the rim. Its run great since day one though. Slow leak is no big deal to me. Just a few psi between rides. The scale says my bikes a half pound heavier but it rides lighter and rolls better so i don't know. They may have used three scoops.

I have had two burps while running low 20's psi and landing from "whip" type jumps with the front wheel turned upon landing. I lost some sir once and most air the othe time. I pumped t back up and kept riding. I run 25-28 psi now and use the enduro on the trails and the dj bijke for jumping and riding the streets.

If you read the first post in this thread you can see the weight savings, he saved over half a pound. You should have saved weight by going tubless. :confused:

I believe it is because my lbs used 3 scoops of fluid per wheel compared to the OP's one scoop per wheel. I have 26x2.3" tires. Tubes i was running weighed 170-220 grams. I didnt weigh every tube though. I definitely saved weight over a tube with slime. I'll install my next tires myself and experiment with minimum sealant values. Like I said I live in goathead country so three scoops prevents customers from complaining about flats and "this stuff dont work, i want my money back" etc. Its an epidemic on the streets and neighborhoods of Northern Utah. Dependability trumps weight in non race environment.

Like i said before, they pedal like they're lighter but the scale disagrees. I still like it better than tubes.:)

It was a large cactus spine from Soapstone area, and it slowly went down in air pressure and I had put a tube in. It was a major pain trying to break the bead from the rim to change for a tube. That sealant is super strong but I didn't see any advantage to tubless besides a slightly lower pressure, 30psi front and back. Any lower PSI and the 2BLISS tires would feel squirmy.

Soapstone eh? You must be close to me. I ride Soaptone at the end/start of the season when everything up high is still snowy. I am gonna go tubeless this week ok my new Camber Comp Carbon. I shall report back! Might try to ride something near FoCo this weekend, even if it is a bit nippy.
