Question for the Mt bikers - tubeless sealant?

Constantly pumping up my tubeless tires is driving me nuts - does anyone have any experience with the tire sealants i’ve seen - Stans, the bontrager stuff etc? Is it used primarily to stop slow annoying leaks (ie tires losing air overnight) or to seal the tire if/when a thorn or something punctures it?

thanks!

Both.

Stans is the stuff you want.

Nipsy,

Sealant will cover you for both these incidences. I prefer Stans mostly because it’s what’s available at my LBS.

i am retro, but old-fashioned tubes work pretty darn well for me. i rarely have to pump up my mtb tires at all. (but not so retro that i don’t use full suspension with some decent travel.)

related, if anyone knows, if you have, say, a 5 mm slash in one of these new tubeless tires, is the tire basically toast? or can you fix it at home and keep on using it? can you fix it on the trail and keep riding?

i ask this because this has happened to me more than once on the road and some duct tape in the tire and a spare tube did the repair fine (i carry a bit of duct tape with me).

comments?

Stans, although I’ve heard the Slime and Bontrager stuff work just as well. They will stop the slow leak and help seal punctures. If you are running non-tubeless tires on tubeless rims they will definetely leak quickly without sealant.

you carry a spare tube for any big slashes or things the sealant won’t seal. It’s a bit messy but you just take the special valve stem out of the rim, pop in your standard tube, booting the tire if necessary and reinflate. You can’t boot it with tape though as there’s goo all over the inside of the tire, you’ll need a dollar bill, some tyvek or something like that. You can probably superglue or patch the tire when you get home.

I have been using tubeless latex since 2000, before Stans

Go to a craft store like Michaels and get some Latex Mold Builder

mixed with water and inseted into the tubeless tire, it is the same as Stans, and you get a ton of it in the jar
.

ah, thanks.

wow, complicated. and you still have to carry a bloody tube.

Has anyone tried the Swiss made Eclipse Tubelesskit: http://www.tubelesskit.com
or DT Swiss Tubelesskit: http://www.dtswiss.com/index.asp?fuseaction=proline.bikedetail&id=50

I think DT Swiss’ kit is a rebranded Eclipse Tubelesskit, they look very similar.
