PEATY'S TUBELESS SEALANT - EQUIPMENT TEST

Updated: Oct 11, 2019



Having more and more options coming to the market for tubeless sealants, it is important to find one that not only works but keeps working again and again. Peaty's says their product does just that and more.


With not just the sealant but the full package of tape and valves to go with it for the complete tubeless setup. For the past year we have been putting it to the test in a selection of bikes and setups, learning a lot in the process.

How to Set Up

A quick guide to setting up.


  1. Clean the rim. Take off the old tape and wipe the surface that the tape will be applied to.

  2. Find the valve and allow about 2” or 50mm of tape overlap before making a full circuit of the wheel, make sure to keep good tape tension so the tape forms to the rim nicely. Overlap the valve hole again by the same amount.

  3. Find the hole. It is super easy! If you're struggling, the Rim Job Tape is transparent, so you can find the hole easily if you hold it up to the light.

  4. There are two ways to do this next part. Either fit the tyre all of the way on and fill the sealant through the valve. Alternatively fit one side of the tyre on, fill with the amount of sealant you need and then fit the other side on.

  5. Now you will need to bead the tyre onto the rim. This may require a bead booster pump but if your tyre is a tight fit then a good track pump will suffice.

  6. Give the wheel a good shake about to make sure the sealant gets to the required places.

  7. That's it, done! Just check the pressures and ride without worry.



The Mistakes That Were Made


It is always easy to point the finger and blame someone else for mistakes made. After a few occasions that were unsuccessful, the issues could all be pointed to user error…. in this case, my error. Below are a few little setups that I did, some in a rush, some testing other products. Each time the sealant just did not have the chance to work as it should.

  • After cursing at the fact that a double puncture messed a ride up a while back, it would have been easy to say the sealant should have worked. Having a think back, it was the lack of a refill that caused the holes not to seal. The tyre was fitted with no issues for 8 months prior to the puncture and at no point was the sealant topped up. Not considering the amount of punctures that had already been fixed, it's important to make sure the sealant is topped up. Lesson one learnt.



  • When testing out a tyre protector before heading out to Madeira a few months back, the Peaty's sealant was added to the setup. Here the protector sat between the tyre and the liquid, acting like a foam cushion. After getting a puncture from a pinch flat, the hole created was about 4mm in size. Normally this should have been no problem for the sealant. But the puncture protector that was fitted stopped the glitter platelets getting to the hole to plug it up. Lesson two, don't over complicate things with armour. Just use a good tyre and the standard sealant setup.



  • The last cock up made was only a few weeks ago, where a rushed tubeless setup meant that the rim tape was not changed. This tape was the plastic insert that some wheel brands use. Thinking that this would do the job, however the tyre just did not seal. After cursing the world and adding loads of sealant, it was only when I got back and cleaned the bike that the problem reared its ugly head. The sealant was coming from the nipples. After removing the tyre, cleaning off the wheel and fitting some fresh Rim Job tape, all was well. Lesson three, just use the kit as it is supposed to be used. The correct tape, valve and sealant.



Feeling


With the list of mistakes made while testing above, it should be apparent that everything has not been straightforward. But every time something went wrong, there was a clear reason that showed that the sealant itself was not at fault.

Having setup four bikes with Peaty's sealant for the test, two of these have never shown a single fault. Even to the fact that Alex’s trail bike has not needed any attention for the entire test. Maybe it would be wise to give it a top up…

Peaty’s have put some real attention and thought into the products that come hand in hand with the sealant. The Rim Job tape is one that really shines through in our eyes. This transparent, malleable tape not only sticks well, it comes back off without leaving much of a trace. This makes life far easier when refitting some new tape. Before using this it would have been Gorilla tape all day long, but all of the bikes have now been converted to Rim Job. The aluminium valves with their lifetime damage replacement policy also hits a great note. The valve caps look pretty trick too.



This test has obviously had its issues, but when this setup is done correctly it more than does it’s job. The mixture stays liquefied in the tyre and at no point balls up or goes off. The sealant is clearly working well when the circumstances are correct. The two bikes that have had the correct components unchanged throughout have not had any issues whatsoever. One Peaty's tubeless setup is on a downhill bike, running relatively low pressures and has even got enduro tyres fitted. This has been ridden all over the UK including Antur Stiniog. If you have been there then you know how rocky it is. So the setup is clearly working well.

Having had a few good thorns to pull out of my own personal bike that sealed up right away, and even the occasional small slash being dealt with more than adequately enough. There are clear signs that punctures are being sealed more often than we may realise.



Limitations


There is one thing to mention here… I got caught out by it so just stating a point. This is a sealant, it forms a permanent seal. Whilst you can easily wash if off the bike, wheels, tyres and even clothing when it is freshly applied, if you leave it go off then you will be in for some work. I let this go off on a wheel once and don’t get me wrong, it comes off in the end, but you will have to scrub it hard to remove it. After chatting to Tom from Peaty’s about this he said that it is still water soluble, but if the customer wants a permanent seal then it has to be durable. Wash it off before it goes hard guys. Then there will be no issues.

Also, best to make sure the better half knows it has glitter in. It can be an awkward conversation having to explain why your hand, arm and the kitchen sink has glitter on it, not to mention the hosepipe and the dog too.


Verdict


The Sealant does its job as you would want it to. Under certain circumstances it may not. But before you go getting in a tizz, check that you have followed the setup guide and that it has been topped up recently. The biodegradable formula is something that is a key topic at the moment and the ability to use refill bottles for multi use also makes us happy.

Peaty’s are doing a great job and we look forward to seeing what the future holds for the brand. Its great to see the offer of a full package that includes everything that you would need to get you going when setting up tubeless. This also removes the ability to cock up a setup by using the wrong combination of products.
