One of the best tubeless tyre goo’s on the market, up to now works well, had a few thorns in my tyres and tyres are still up so all good.This handy pouch is also good for keeping in your back pack for emergencies.

I thought having a new eMTB with tubeless tyres was going to be a Godsend - it turns out I was wrong! A new Trek eMTB with, I assume, Bontregar sealant, failed miserably within the first few weeks. A puncture happened, but instead of sealing it the sealant just continued to pour out, never once sealing the hole. I repeatedly pumped the tyre and limped home. Left the tyre inflated with the puncture downmost, but the next day when I came to pump the tyre up to correct pressure, it just spat out the plug that had formed. I had to remove the tyre and patch the tyre itself. Then clean out the old sealant and replace it with this product, as it was the highest recommended. But, you have to change it every six months! If I was on my old bike and got a punctured, I would have had a spare innertube, that I carry, fitted and been on my way in less than five minutes. With tubeless it only put an end to my ride and took two days to get back up and running. Isn't technology wonderful. If a standard tube fitted these tyres I would have gone back to tubed. Only they're wider and the tubes cost mega £. But if I get another puncture and this goo fails it's getting a tube. And I'm not spending £8 every six months when I can just put an innertube in there for life!

Works well

I would never go back to conventional inner tubes. This sealant has never let me down. If you get a puncture on the trail keep riding and it will seal. Love the easy to use pouches with a measure gauge so you know exactly how much to fill up.

Great safety tool which we’ve used in sons e-bike tyres.

I’ve tried a few types of sealant over the last few years and this kit is right up there. The UV reactive liquid makes finding small leaks really easy meaning holes can be plugged really quick.Tape is easy to install. Not had any deflations since switching.Valve cover that doubles as a core remover is a helpful feature especially if you need to top up on the road.Flexible sealant bags are also much easier to carry although a smaller cap would be ideal.

blurb says that a valve removal tool is provided. It isn't which is a total pain for me as I now have to go out and buy one. The amazon description is wrong or I got sent the wrong thing. All I received is the bag.
