    Dude....are you seriously going through all that trouble to save 100g??? 100g = 3.5 ounces. By the way, I switched to UST recently. Went with XT rims at 1700g. I haven't had any problems - no Stans either or sealants either.

    100 grams is about 1/4lb in rotating weight. rotating weight means much more than dead weight. i can feel the difference on my bike, but i ride an 18lb hardtail, not a 36lb fs bike.

    OK...then instead of 3.5 ounces, it's 4 ounces (1/4 pound = 4 ounces). I get it if you're not going through a lot of trouble to shave off 1/4 of a pound, but it's not worth it to go through all that hassle of selling your old rims and tires and buying new rims and tires and tubes. Not a great "bang for the buck" upgrade.:?:

    I saved about 1200g because I swapped out my rims for something lighter.

    My previous wheelset was 4100g w/ tires = 9.04 lbs

    My current wheel come at 1659g + (2) 99g tubes + (2) 519g SB8 = 2895g (approx 6.3 lbs)

    If I decide to run tubeless my 1659g wheels with my (2) 800g nev ust tires = 3259 g (approx 7.2 lbs)

    Yeah, my friends think i'm crazy.

    have you considered running your current sb8's tubless? they hold up pretty good.

    I would like the switch to SB8's tubeless. But I'm still deciding how I should run my wheels. On kenda's site, it says the SB8 UST is 888g, heavier than the nev in size 2.1. Funny. But I bet it still rolls faster.

    Speaking of which, anybody want to help me with a new set of tires? (Shameless thread jack) :)

    Great Scott!!! That is genius!!! :clap:

    1659g + (2) 519g = 2697 g (approx. 5.95 lbs) :beer:

    thats how i've run them for about 3 years now without any issues. they have the same sidewall thickness as stan's ust tires, and they fit decent on my rims, so no chance of them debeading.
    like i said before, the biggest thing is cleaning the inside of the tires very well to get off the mold release, otherwise the stans wont seal them

    Back on tubes.

    Why?

    Well, having no compressor at home it was a drag running out to the gas station, or use C02 to get a tricky bead to seal.

    Awhile back at Fontucky, I had a Stan's blow off on my front wheel that caused a taco and an OTB. The long 4 mile walk back to the car, and the heckling from all the DH kids on practice runs still haunts me. :lol:

    There's no weight savings.

    With my riding style, and trails I'm lucky I haven't flatted much.

    When I did have small punctures, Stan's didn't seal them. I'm guess I was too lazy at the time to periodically take the tire off to refresh the sealant and remove the golf ball size clump of dried sealant. Probably b/c of the no compressor at home thing and the PIA of re-setting the bead of the tire.

    I'm kicking around the idea of going back and giving it a try again. But I think I'll wait till there's a true UST rim and UST tires I like. i.e. lighter. When I was on 26" ers I had really good luck with Mavic 819 UST setup. Right now, I'm done being other folks R&D trying to figure out which tires play nice with Stan's rims.

    i saved 1/2-3/4lb, depending on if i ran standard or ultralight tubes.:?:
    as for the golf ball sized clump of sealant, tires never lasted me more than a month or so before they were bald, so that was never an issue.
    i hear ya on the compressor thing though, if i didnt have one, it'd be a PITA unless i was running a true tubless specific setup, and then it would be heavy as hell.

    I've been tubeless for a while now. I just moved from an older pair of Mavic Crossmax UST rims to some Stan's Arch rims... the "no tubes" thing. I was pretty leery of trying to go tubeless on this setup with normal tires and about 2oz of Stan's goo, but I thought I'd give it a try anyway. It's not that hard to do and I'm surprised at how well it's working.

    Performance-wise the Schwalbe tires fare the same. They're great. The bead seems strong and they did give a pleasing pop when the bead set. It also wasn't difficult to set with a regular floor pump and they haven't lost a bit of air after sitting for a couple days.

    I'm still nervous about the sidewalls though.

    I went and bought some 240S hubs from Rich Houseman for a Stan's Flow 29'er build up. Already have a compressor, find that installing tires with Stan's and sealing is a bit time consuming and messy. Can't seem to feel the lower rolling resistance between running Stans juiced tubeless or tubed tires. Won't miss changing out a tube, might miss being able to air up with a hand pump in my Camelbak and getting a bead to seal going tubeless, but that's what a tube in the camelbak is for.

    Have heard others recommend that at my weight, I don't go tubeless in the front tire.

    I like to swap out tires every once in a while...do those running tubeless find this to be a PITA?

    Does anyone run stans sealant IN tubes?

    I swap tubeless tires all the time.Once you get the hang of it,it's not a problem at all to swap tires.I've never heard of running Stan's in tubes,I imagine you could do it with a presta valved tube.There are tubes with slime in them.-Lloyd :wave:

    I tried to read thru most of this thread... but what I've been hearing:
    Tubeless on true UST rims, like Mavic 819's, seems pretty robust.
    Tubeless on non-UST rims is a mixed bag of issues.. burping, seating, CO2's, etc
    No real weight difference.
    Fewer flats on tubeless... especially of the sticker or snake bite type.

    Am I getting it?

    I'm still tossed up between going tubeless with Mav 819's or tubed with Mavic 521's.

    You got it.

    I've been very happy with my UST Mav 819 set up.

    Seems to be it pretty much - at least that mirrors my experience. I'm running UST tires with Stan's sealant on UST rims for about 20 months now. I haven't had a flat of any kind yet (the only UST flats I've seen were severe cuts), and I like the performance better. I don't see going back.
