Holeshot Biofibre Tubeless Sealant

As a general rule we recommend using 2ml of sealant for every mm wide your tyre is. So for example a 2.4" / 60mm wide tyre should have 120ml of sealant.

*Quantities quoted per tyre. For wider rim / tyre combinations and / or additional puncture protection we recommend adding up to 30ml more sealant to the above quantities.

Sealant can last up to (and a lot of the time beyond!) 6 months in your tyre in temperate climates. We recomend you to always check sealant regularly and top up as required. Depending on how much you ride, and how warm it's been, we recommend checking your sealant every three months. For hotter climates or regularly ridden wheels check every month.

Most of the time just keep on riding and the sealant will do the hard work for you! Escaping air will always suck Peaty’s Holeshot Biofibre Tubeless Sealant towards a puncture, so most will seal while spinning. But if a big hole is still leaking, stop and rotate the wheel so it’s at the bottom and tap the tyre to rush maximum sealant to the right spot. For punctures on the sidewall of a tyre you may need to lean your bike over and tap the tyre on its side so the residual pool of sealant is sent to cover the hole.

If the puncture is too big for sealant to fix then check out our Holeshot Tubeless Puncture Plugger Kit.

CO2 blasts out of the inflator head at around -50 degrees, so it will freeze any sealant that it comes into close contact with however, since our Holeshot Biofibre Tubeless Sealant formula is a water-based formula (which means the latex is suspended in water rather than chemicals) it will soon defrost and performance won’t be affected.

The easiest way to check your sealant is to fully deflate your tyre and pop one side of the tyre bead off the rim so that you can see the inside of your tyre carcass.

What you're looking for is a good coating of sealant all over the inside of the tyre then a pool of residual sealant which gathers at the bottom of the tyre when left for a few seconds.

If you have a coating of sealant but no pool of residual sealant then simply add some more fresh sealant to your desired amount.

In the unlikely event your sealant has fully dried up (naughty you for not checking it for so long!) then you can simply re-add the correct amount of sealant as stated on our quantity guide and get riding again. This fresh sealant will help to rehydrate the old sealant and make it easier to remove from your tyre carcass.

Once you've checked the sealant - and topped up if necessary then simply pop the bead back onto the rim and re-inflate. Just be sure to wash away any sealant off the outside of the rim to prevent after re-inflating because it's not easy to remove once it's dry (it has to bond to rubber after all!).

Yes, Make sure you thoroughly clean the inside of your tyres of any dirt, oil and other sealants before you first setup tubeless. New tyres are often coated on the inside with a residual chemicals from the manufacturing process (specifically release agents) which can react with tubeless sealant and cause it to solidify prematurely or reduce it's ability to fully seal punctures.

Let the tyre dry fully after cleaning and wipe the tyre with isopropyl alcohol or our Peaty's Disc Brake Cleaner before applying sealant.

This heavily depends on what type of sealant you're already running.

Our new Peaty's Holeshot Tubeless Sealant is fully backwards compatible with our OG Tubeless Sealant, so you don't necessarily need to wash out old sealant when topping up with new Holeshot Tubeless Sealant.

However, if you want the full benefits and sealing power of the new Holeshot sealant then you should fully replace with Holeshot Tubeless sealant.

If you're using another brand of sealant then we can't guarantee our sealant's compatability, simply because we have no control over the chemicals and addatives they use.

Top tip: The caps on our aerosol tins are a perfectly sized scoop to scrape out old sealant. This sealant could then be re-used in a new set of wheels instead of being thrown away.

In short, yes as long as your rims and tyres are tubeless ready, you can use tubeless sealant in road, gravel and cyclocross tyres.

Tubeless tyres rely on a thin lining of butyl rubber on the inside of the tyre to hold air (and sealant). Some new tyres (especially very thin / lightweight tyres) can have tiny imperfections in this lining making the tyre slightly porous, so it is normal for new tyres to show little spots of sealant on the sidewalls where sealant is having to finish off the job the tyre manufacturer started 😉

This is fairly normal and should seal within the first 24hrs but if your tyre continually leaks out of the sidewalls then contact your tyre manufacturer as there may be a larger fault with the tyres construction.

Porous tyres may absorb some sealant within the first few riding hours to help seal these tiny holes so It's best to check your sealant levels after two weeks of application and top-up any lost fluid if required.

It is always best to remove / wash away sealant as soon as any gets onto a tyre, rim, frame or forks.

Once exposed to air, sealant is designed to solidify to a point that it will bond with rubber so it has to be pretty hard to remove by nature. Any less and it wouldn't bond with rubber well enough.

It’s not always possible to wash off thoroughly after a puncture mid-ride, BUT we recommend a quick squirt with a water bottle (or splash from a puddle or stream) usually gets the worst off out on the trails.
You can then do a thorough job with a hose and brush when you get home or back home, ideally within the first 24hrs.

For well dried on sealant, the best method we find is soaking the dried sealant in warm soapy water then persuading it off with some elbow grease and a soft sharp edge (like a credit card / fingernail or ice scraper) - just being careful not to scratch the surface of your paint.

An alternative is to use our Peaty's Disc Brake Cleaner but you should always be careful when using this for prolonged periods of time onto painted surfaces.
We always recommend testing on a hidden area of paint first, to test for any raint discolouration or possible damage, before using elsewhere.
