Product Description

Stan's Race Sealant

The Next Level in Sealing Power from the First Name in Tubeless

For nearly fifteen years Stan has been quietly formulating a special racing version of our legendary sealant for many of cycling's most successful teams. Working with athletes who push themselves and their tubeless systems to the absolute limit, we've developed a proprietary sealant formula with close to twice the amount of our standard sealing crystals plus our special XL crystals capable of sealing even larger punctures.

Stan's Race Sealant's combination of large and smaller sealing crystals interlock to form a lattice work that not only seals but strengthens and reinforces the area of the puncture, allowing for an entirely new level of sealing performance.

    Customers say

    Customers like the performance of the sealant. For example, they say it works well, is fast, and better than original Stans. Some say it's great for butyl-lined tires and that it doesn't allow air loss after a month. Opinions are mixed on the quality and value of the product.

    Customers like the performance of the sealant. They say it works well, seals fast, and seems to work better than original Stans. Some say that it works great with tires that are lined with butyl and that it doesn't lose air after a month.

    "...I'll see if it dries faster after 4-5 month, but so far it seems to behave well - and in any case, the added "sealing power" is already worth it" Read more

    "...sealant and it’s been over a month and my tires are still G2G no loss of tire pressure and I’ve ridden over many a N.C. pine cone...." Read more

    "...I have used this on three different bikes now, and know it works well, especially on the thin gravel tires I use...." Read more

    "...This stuff works great with tires that are lined with butyl - most black tires are and almost all MTB tires are...." Read more

    Customers are mixed about the seal quality. Some mention that it's designed to seal well, and can seal 3mm holes easily. However, others say that it wasn't able to seal, and that it seems to be expired or poorly stored.

    "I gave it five stars because it seals tires just as good as Original Stans. But it's not as easy to use...." Read more

    "...Pros:- actually seals larger holes and more little tire/rim, or even taping issues-..." Read more

    "...The only negative is you cannot use a sealant pump so initially you have to break the side wall bead to add the sealant, but heck it works so well..." Read more

    "...With these tires, this will seal 3mm holes easily...." Read more

    Customers are mixed about the value of the sealant. Some mention it's completely worth it, worth the extra $$ when you want it to work, and a godsend. However, others say that it'll be going in the trash.

    "...hundred miles, there can still be liquid in the tire, but it's no longer useful...." Read more

    "...Then I tried this stuff. It's a bloody godsend. Haven't had any problems since...." Read more

    "...the valve hole, I think the stuff is good, but not really worth the increase in effort over the usual stuff." Read more

    Stans race barnacles

    Stans race barnacles
    I've been trying it out for a year after some issues with the regular. Seems to last a few months for me between top offs in VA climates. It's time for more when the tires seem to lose pressure week to week.I've seen it seal some pretty good holes and I've been told the barnacles you find stuck to the inside of the tire are where the sealer clotted a hole. I've found some holes on top ups that I never noticed while riding.The downside is you cannot inject it in the valve stem. I'll take the hassle for it working well.Pretty expensive. I'd say I top up every 4/6 months. I'll try to report back as my riding group is testing a few sealers and I've been the stans race user.Update: I just used up the last of my first bottle. I'd say it's been about a year and I was pretty generous. I haven't had any noticeable holes but did find barnacles fused into the tire carcas on top offs here and there evidence of a small hole. Ordered another bottle to keep trying it.
