Slime Pro Tubeless sealant

Just prior to an active mountain bike season with some planned races I thought it might be a good idea to change the tubeless sealant in my tires. It's been a full year and that's the longest I've ever gone without replacing the sealant and I was curious to see how well it held up. Over time the sealant hardens and or becomes thick to the point it's not effective at plugging punctures any more. I've been using Slime Pro Tubeless sealant and It's worked very well to the point I've slashed sidewalls up to a couple of centimeters and I've still been able to get back to the truck with some air still present in the tire or with a quick shot of CO2. Granted the tire was trashed but I didn’t get stuck miles down the trail. The Slime folks say it's good for 6+ months in a tire and upon dismounting the tire the majority of sealant was still liquid, a little thick but still thin enough to plug a puncture. Nice to see after a year. I'm running Mavic Crossmax SLR 29er UST wheels and Schwalbe tubeless tires so the tubeless tire rim combo is top quality and specially made for tubeless. For bike tires you need approx. 3 - 4 ounces or 89 to 118 ml per tire, I run 29 X 2.10 and use around 100 ml per tire. Also the Slime website says it contains some form of antifreeze and can be used on temps -4 F (-20 C). Shelf life is 2 years and it's compatible with CO2 meaning it will not freeze. Overall a very reliable product.
Very dependable product, I've been using Slimepro for
around 4 years now and have been impressed. 

You can see some residue from the sealant right after
mounting the tire and filling with air. It sealed an
existing puncture quickly.

Mavic set the standards for UST tubeless design
and it's works very well.
