    I’ve got a bunch of unused stans. I don’t like the stuff and think sealant is a messy solution so you’re welcome to use some. binderdundat got the tshirt.

    Of note, if the rim is a hookless design it may not pop. Even with a hooked rim it doesn’t always pop into place. It only pops if it was out of place in the first place.

    So your tires are dry? What happens if you get small punctures? My older tires are scraped up and weep sealant, but hold air for days. Can’t say they’d hold up without the messy slop inside.

    Yeah not much of a hook on the rim. Done the second one but trimmed gorilla back with a blade. Same result… Think both are a success. Holding well over 40 psi…. Even rim bead marker. Think we’re good. I owe all of you a beer! Come see me trail side… I’ll be the intermediate rider probably fixing a tubeless fuck up! Hahaha. This seemed easier than it should have that’s why I’m skeptical but fingers crossed!

    What do you mean “are my tires dry?”? I just finished setting up. Haven’t rode. I can still hear sealant sloshing around. Shook them for 15 mins… What I said was because I didn’t hear a pop seating the bead I asked am I at risk for giant burp or blowing off the bead? I’m going to let them sit a bit. Then easy road ride. The. Let out some psi and see how the tire stays seated… Unless there are other suggestions.

    I eliminated tubeless from my bikes a few years back. As a former mechanic/importer/amateur racer I’ve tried almost it all, from the original maxxis system to ghetto tubless to UST and then to the stans style setup. The last straw was dealing with a mess well into an epic ride just to put a tube in. That along with the fact that I needed to always check psi before rides as if it went too low it’d burp. I also can’t run low pressure or I burp it anyway, so most of the low pressure benefits aren’t something I saw. The procore system would solve most of my issues but it’s expensive and weighs a lot and you’re still adding sealant to it because it doesn’t prevent punctures. Sealant dries up as well, something that requires top offs.

    2 years ago I cleaned the stans out of my highrollers and CX bikes’ tires, put talcum powder in along with a maxxis tube and I haven’t had a flat since other than breaking a valve stem. Knock on wood. The dents in my rim don’t affect holding air, there’s no mess IF I get a flat on the trail, and if I forget to add pressure before a ride I don’t need to worry about loosing all my air in the first few corners.

    Ultimately, I have a lot of experience with it, but just got sick of dealing with it: a liquid that we put in our tires…… It also doesn’t help that I was swapping tires out pretty often for different tracks or trail conditions. Used to have a ton of tires to chose from.

    So yea thats why they are dry. haha.

    Ledbetter, if you need more let me know. I’m in burlington on weekends, don weekdays.

    Riding a lot of gravity stuff? I personally love tubeless. I only switch my tires about twice a year (late spring late fall) so it’s not a huge deal. I do have to check my tires more often, but only cause if the pressure gets to low i don’t like the ride quality on the back with a mushy tire. My front can get well below 20 before it’s really a thing. Months into a set of tires and they’ll hold pressure for close to a week before I feel I really need to check the pressure.

    I find UST rims and Schwalbes to be burp free, but that’s just my experience. They’re also a combination that is a giant pain to get set up compared to say Specialized, but I’ve taken that to mean the connection is tight, which may be why I haven’t burped a tire in like 4-5 years. A friend is running different rims with Maxxis TR tires and it’s burp city.

    As for dents, I have lots, haha

    yea every time I read about a new tubeless tech or tire I think about going back. Yea, mostly trail but I like to session jumps or hit jump lines/dh. was racing DH for a few years between 2002-2010. And yea, UST rim has tighter tollerance and a better fit for tubeless, which results in less burping. I’ve got WTB i25 rims now, which apparently set up for tubeless well, so maybe I’ll give it another go next season. They already have gorrilla tape and I’ve got the valves, but stopped just shy when I was building her up. Said F it when I remembered the trouble I had. haha

    Well my tubeless set up seemed to work… It had just rained (must have rained just over Short Hills, almost didn’t ride but figured it wasn’t enough to soften the trail… Horses damage the trails there a lot so thought our bikes wouldn’t do much). Lots of clay and we were fighting for traction. I started with my normal PSI 28, 26. Had to let some out. Don’t have a digital gauge. Then I let out some more and found some great traction and control. Checked PSI back at the trail head when done and was just under 20psi on both! Wow I wouldn’t have even noticed because although it was greasy and we were riding at safer speeds, didn’t feel any drag. Can’t wait to ride in normal condtions for a comparison. Anyway no burping issues or leaks. Seems like a success.

    I have the same issues as @renegade Hardware when it comes to burping and tearing tubeless tires off of rims. I mostly run tubeless because my local trails are infested with various thorny plants and several sections are covered with broken glass. I got sick of fixing flats all the time and since I already had tubeless rims I figured I might as well do it and put an end to the flats. Still didn’t stop me from exploding a tire off the rim when I slammed a root wrong, but one flat a year sure beats one every week.

    You’re so close, just give’r a go! WTB rims can be a bit of work to get up on, but I have complete confidence in their ability to hold onto a tire as do others who can ride far bigger stuff than I do. Tires can last months and lose little pressure if the tape is done right, and I find gorilla does a really good job.

    Ok so now I gave these diagonal lines on the sidewalls of my tires, more so on the Maxxis Ardent Race in the rear. Can see the thread showing just barely. Have 300km on these tires with not much rock exposure. Do I need to be looking for new tires soon??!!

    If the lines aren’t weeping sealant moisture, I’d say they are not a problem. Even if they are weeping a bit, I’d still use them until worn, personally. I’m assuming that your casing threads look intact? If so, the sidewall damage I’ve had that caused blowouts in the past looked way more dramatic than that.

    But monitor them to make sure the threads stay intact.

    So a few weeks later (only one trail ride due to weather and long work week) and my tubeless tires are holding.

    I may have convinced my brother to convert his 2015 Giant Trance 2 to tubeless. Anyone have any problems or can reassure me of success? I have to say the Schwalbe Nobby Nics he has seem thinner/cheaper than my Maxxis Ardents.

    Not sure what rims your brother is running, but I ran Schwalbe Rocket Rons (likely even thinner sidewalls than the NN’s) and Stan’s stupid light alloy rims with piano strings for spokes for years in a ghetto tubeless setup with no issues. But I’m also a relatively light rider with a relatively light riding style. A 220-pound masher with an appetite for rock gardens would likely want a more beefy setup.
