Race Sealant Stan's notubes new srd 2 (2)

It’s kind of crazy to think that 15 years ago, the idea of tubeless conversion was just starting to hatch. Back when UST was attempting to become the “official” tubeless standard, Stan Koziatek began experimenting with liquid sealant and tubeless conversion kits. We all know how that went. Now, tubeless conversion is one of the most common upgrades to new bikes offering the benefits of tubeless tires with the additional convenience of self sealing tires. Mostly.

Every once in a while, you’ll end up with a puncture that just won’t seal. In a race situation (or when you’re far out in the back country) that just won’t do. Following an evolution of more than 14 years for their sealant, Stan’s is celebrating their 15th anniversary with a new logo – plus a new “Race Sealant.” Designed to seal better than ever, the Race Sealant claims to be the go-to sealant when flatting out just isn’t an option…

How do you make a tubeless sealant that seals punctures better and more quickly? It all has to do with the magic “crystals” suspended in the liquid latex blend. Not only are there double the amount of the average sized crystals, the Race Sealant adds larger crystals that interlock with the smaller variety after a puncture forming a clot more quickly, losing less air in the process, and forming a stronger seal. These “XL” crystals supposedly seal even larger punctures and make the seals on smaller punctures more durable. The trade off? For starters you won’t be able to inject it through your valves. The new crystal structures are big enough that the bottle requires a special cap, and you have to pour the sealant directly into the tires. While lighter since you can use less sealant overall with the same results, Stan’s Chris Currie states,

“We’re recommending checking it [the sealant] every two weeks, and it’s really designed for big events or occasions where you really, really want to avoid getting a flat (hence the racing origins).”

That seems to indicate that it will dry up more quickly inside the tires, but Currie also mentions it can be mixed with the standard sealant which will make it easier to add it in for big events, or to go back to regular sealant. Only sold in quarts for $39.00, the sealant uses the same latex blend as the standard sealant so it will have the same shelf life and the same temperature range (down to -30ºf/-34.4ºc), as well as being non-toxic.

Along with the new logo, the Race Sealant is part of the new Stan’s Racing Development program which is “a division within the company that’s dedicated to moonshots, the kind of “innovation for innovation’s sake” projects that have always been our passion.” Like the Race Sealant which has been present on the pro circuit in the form of non-descript black bottles with hand marked labels in silver paint pen, the SRD products will be devoted to helping the fastest riders go faster without worrying about flats. Currie mentions there may not be a huge market for a few of the products, but that they are definitely needed by racers and pro athletes.

  1. Your comment holds absolutely no merit. Mention the name Stan’s anywhere in the cycling industry either in North America or Europe and people will know it. Sure the logo may not be your favorite, but it’s not supposed to be. You just need to know what company it identifies.

  2. *1996 Cannondale team mechanics brew up their own liquid latex mix as their secret weapon to help their star riders go faster and flat less.

  3. Orange Seal. End of story. I’ve used both, and OS is much better than Stan’s. Sorry Stan, use that newfound Specialized cash and improve your product, new logo be damned.

  4. So, they went back to the formula they migrated away from 5 years ago that sealed almost instantly…now they realize the new formula sucks and want to charge more…went Orange Seal and never looked back.

  5. +100 on Orange Seal. Stan’s was fine in the early days of tubeless systems when there was no other choice. They have been surpassed.

  6. Stans works great for me. I like the old school logo purely because I have used gallons of that stuff, and know from use its a great product. Not to mention about 5 wheelsets with stans rims. Mariposa, cafe latex, green slime, orange, have all been crap for me. But it has been a while since trying others.

  7. If their was a marketing strategy behind the log redesign, they could have dropped the No Tubes and just ran with STANS. They have been around long enough in the industry to be recognized by STANS alone.

  8. I’ve been a Stan’s cusomter since the very first day. I only ride his rims, I even got a Valor wheelset because if carbon only with ZTR.

    However, I really got put off by the sealant a couple of years ago. I would always get these latex balls within short time. Since there are so many alternatives out there I’ve never considered going back.

    This new product does not really sound that great. Seriously.
