Going tubeless, giggidy.

My experience:

Stans does not seem to last as long. This means after about a month I have to keep inflating my tires every couple of days.

Slime, on the other hand, seemed to work much better overall, although it is a bit nastier to deal with.

Unfortunately, I bought a litre of stans, so I'm stuck with it until my supply runs out.

Also, I have heard of others having probems and have myself experienced a problem with Maxxis DHF UST tires in which the tire itself pinch flats just above the bead. This sucks, as the tire is not repairable... in Canada, this really sucks, because tires are $90. Anyways, this is apparently a compatibility problem with these UST tires on Mavic 823 rims, and my regular Maxxis DHFs are currently trouble free.

Hope that helps.

ps overall, tubeless is a great way to save some weight, run low psi, and avoid pinchflatting. Good luck!

i find slime better to deal with, doesn't stink, water soluble, and washes right off... works really good too. you need to mix it with a bit of water to get it flowing.

So far Joe's treats me quite good. Used it for long periods of time and had zero problems with it.

or, if you get good ust tyres... run no goo at all.

It's still a good idea to run a scoop of sealant in the event of a puncture.

I made the switch from ghetto-tubeless to real-tubeless. I'm using ust tires and I didn't need any sealant, but I put in about 1oz just to be safe as opposed to the ~4oz I was using with the ghetto setup.

If your using UST tires, I would agree to this here. They have one thats made specifically for the tubeless tires, and it doesnt dry out like stans does, doesnt smell, and is a snap to clean up.

If your not using UST tires, then I would have to say use the stans, I havent used the other, so I am not sure how it works, and would have to go with what I know works

If you have UST rims, get UST tires. You might not even have to add sealant.

Sounds like I will be going with Joe's. I will keep sealant in just incase a puncture does happen. How bad would it suck to be riding along, get a puncture, have to stop, and put a tube in, when I could have just had a little fluid in them.

Edit: I wouldn't be using UST tires, just a UST rim for now. After I use my specialized pro chunder tires up, I will probably go for a set of prowler mx.

If your not running UST tires, then your going to NEED the sealant to make it hold air in the first place. Remember the idea behind the stans system is that it coats the inside of the tire so it will hold air without the tube. Sersiously try to get some UST tires, thats truly the best way to go about it

i tested them with non ust tires too, worked like a charm. the tires i used were intense tires, if anyone is bothered. they definately have a nicer shape bead then maxxis non ust tires. so not sure how they would work there.



as for using sealant with ust tires, there is really no point. unless you ride where there are load of thorns. because the main way you get a puncher on full ust is slitting the tire just above the bead, which stans does fak all to seal back up. with that, you just have to run correct pressures.

for ppl who are still have problems slitting ust tires, non ust tires would be the way to go, they have stronger sidewalls compared to their ust counterparts. expecially maxxis ust to non ust with inserts.

tony, you dont need the sealent, i only had sealent in the tires u flatted because i flatted them once before and even a patch doesnt work, get sealent but only use it if u need to.

Funny you'e saying this.So you wouldnt check your pressure otherwise? I check mine every single time I take my bike out for a spin,in fact I even check the pressure in my suspensions as well and there's always a slight variation in both.

823 rims with Stans; Ive had great success but if I leave the bike untouched lets say for more than 2 days,I definitely need to pump it up.Other than that Ive never had real problems while riding

^^ wow, if my tires have stans in it and i take time to set it up properly, i can leave it for a whole week with out any noticable change in pressure. even with non ust tires.

you might want to check your rim for cracks and give your valve a good cleaning.

idk if i am special or something but i dont notice air loss in my tires for up to a month and a half.

(however i do not check exact pressure-if it doesnt feel soft i leave it)

823s
minion UST
stans

I have 823s and have run Hutchinson's and Michlein's without Stan's and the pressure has held for over a month. I now run a bit of Stan's to seal holes. Although every puncture I've had Stan's didn't seal since they were so big.

I always thought UST tires had the stronger sidewalls...I guess they have to reduce weight somewhere since they make the bead thicker so it clings on better to the rim

Or YOU might want to get a digital pressure gage and see for yourself what I mean.During summer when I ride the bike park every day there is always a SLIGHT difference in pressure when I check it.Im not saying a difference of 10 psi but sometimes it can go up to 5 psi in one day...

Ive had 2 set of Crossmax SX and Im no on my 3rd set of 823 and ALL of them were the same.I dont think I need to check the rim nor the valve.

That being said Im really anal about tire pressure ,I'd like to think it makes me go slower if I dont always have the exact same pressure in there...but Im sure it doesnt make a difference at all but thats how I am.lthumbsdown:

i am pretty sensitive to tire pressures too, i run them as low as possible with out them folding over in corners. which generally comes to about 21 psi minimum, i go a bit higher if i am hitting my rims. i weigh fak all, 140lbs so i can get away with that.

are you running much higher pressures? the higher the pressures, the faster your tire would leak for a given hole size.

not saying there is anything wrong with your set up, just saying that i am used to tires holding air. if they dont, i give the beads a good clean and use sealant if needed, and reinstall them carefully.

Not that much higher,Im 150 LBS and I run 28 psi rear 25 front ... I dont care about it as much on my rail bike, still I always check it but I can usually go a few days without loosing more than 3-4 psi.But when I ride my DH sled in Whistler , oh boy, if I dont check it everytime Im in for a "hit the rim" party...

iam bout' buck fifty, style: hack racer boie, went getto with 2.7 3c minion Fs, like how they drift / clear mud, but miss my 2.5 nevs when i want the added wet rock/root traction, under 25psi and things get really squirmy. running high 20ies front, low 30ies rear, with slime, pump em up once a week like how dent free my rims are. plus the ability to plow hack lines seems to improve as the bigger ( the 2.5 max look tiny) volume eats up alot of little junk.
