Slime 10015 Tube Sealant - Puncture Prevention for Bicycles, Dirt Bikes, Wheelbarrows and Ride-On Movers

I read many reviews saying that this is not good for mountain bikes. However, I noticed that the same amount of slime was being used in motorcycle tyres and thought that the surface area inside the tube would therefore not be too large within mountain bike tyres. I was right. It works perfectly so far after a month and with a puncture that the slime instantly repaired with no need for a traditional puncture repair patch. But I guess you have to follow the instructions. Don't just put the slime in the tyre and then leave it to stand. You must cycle around on it for about 30 minutes to make sure the layer of slime is distributed well within the inner surface of the inner tube. This is a good product that works well and I expect, will prevent problems from punctures in the future. I like it so much that I will install it on all three family bikes now. One more tip is to take care if you have Presta valves on your bike. But this problem is easily overcome if you just buy very cheap Schrader to Presta valve adapters that can easily be cleaned after the slime has been used inside them.

Very good product

Okay!... I knew nothing of this product until a guy at work told me about innertubes with Slime already inside which plug puncture holes instantly. But I had trouble finding the right size tubes for my bike:-(Apollo Phaze, Mountain, 20" frame)- Then I found this on Amazon. Obviously you have to put it in your existing tubes manually. This did worry me somewhat as the tube on the front wheel was only 3 days old at this point (following a puncture in the previous one). However, by following the instructions on the bottle it was a piece of cake. 20 minutes and both tires filled, and that's on my very first attempt. Taking out the valve cores for the first time was scary - (big wuss, I know) - but the plastic tool they give you works great. Straight out, straight back in and job done. Tire re-inflated perfectly and contiues to hold tight. Though I stress, follow the instructions word for word! One bottle provides enough for both tubes. But you have to guage this by eye. Basically half of the stuff in one tube and the rest in the other; and a transparent bottle allows you to observe the dosages easily. Everything you need comes with the bottle so no need for any special tools or anything. But keep a few sheets of paper towels handy for when you detach the plastic hose after filling. That stuff is funky! For the price it's a no brainer. Especially as the money you will save overall for the life of the bike. I only gave 4 stars as I haven't had a puncture to test it out... Or maybe I have who knows, eh?

Great stuff to stop punchers and it really does work, Well worth the money, Great service, Thank you

I started using this for my kids bike tyres a while ago. FOR PUNCTURE REPAIR: It is dead easy and very quick, no need even to remove the wheel from the bike. The instructions on the pack are straightforward and easy to follow. Once repaired the tyre stays repaired - no need to replace and no worries about future punctures. The wheels seems to function exactly as it did before. FOR PUNCTURE PREVENTION: Also seems very effective, just use as you would if there was a puncture and the inner tube is protected against puncture. I use about 1/3 of a bottle on each tyre. I highly recommend this.

Received two bottles of this slim puncture prevention gel after reading mixed reviews, both bottles arrived undamaged but both had slight leaks (screw on lids loose) only a small amount of slime was lost so they were still good to use , I was going to use this product on my Electric mountain bike and my wife's electric mountain bike , this product is primarily designed to be used with the schrader inner tube vale (car type valve) the black screw on lid on the slime has a built in slot/tool so you can remove your schrader valve but i found the quality of the valve removal cap/tool to be made of plastic so was very soft and two vales came out easily and the other two were very tight so the cap/tool start to split open making it impossible to remove the last two valves so I purchased a alloy removal tool which removed the final two valves in seconds . the slime product when connected with the clear plastic pipe supplied easily and snugly onto the schrader valve and the slim went in easily with no mess at all , I used half a bottle on each tyre and then rotated each tyre to spread the slim , hopefully this product will stop us getting punctures . worth noting it is important still to carry an airpump either cordless electric or manual because if you do pick up a puncture the inner tube could lose some air before the slim seals the puncture.

I bought this without realising it is "for schrader valves only". However my presta valve innertubes have a removable core, I can unscrew the presta valve itself from the main body of the "valve" (the cylinder that actually goes in to my tube). As such, I could pump this in without too much difficulty, I used an elastic band wedged between the plastic tube that comes with this bottle and my valve-body. This worked fine. I was quite concerned that it might interfere with the functioning of the presta valve itself but I have used it for several weeks (at different tire pressures, I let air out when I pull on to a canal towpath and pump my tires back up once I'm on the road again) and it has worked great. No punctures whereas usually I could expect one every 60-100 miles of canal towpath. I have bought myself another bottle now :)

I bought this stuff as a precaution having bought a new mountain bike. To get the slime into the tyre, the valve core has to be removed with the plastic tool supplied. I found this so easy I reckon with the appropriate training, a chimpanzee could do it. In fairness, though it is probably going to be quicker to do it yourself. Am I glad I got the slime? Damn right! Just a week after sliming up, I took my new bike on a ride through the local country park. I realised I wasn't as fit as I thought I was after 30 mins so rode back to the car. On getting the bike back in the house, I looked at the tyres and was horrified to find a large number of thorns in each tyre! I proceeded to remove the thorns and ended up with air hissing out all over the place. I was almost instantly left with two flat tyres. However!... After pumping up and spinning the tyre a few times and bashing the tyre hole side down, the slime eventually filled all of the rather nasty holes. It did take some perseverance as there were many, many holes. I now have two solid tyres again without the need to replace inner tubes. This stuff is awesome and well worth the money.
