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.

arrived on time as stated

This stuff is great. It's the best sealant for standard inner tubes I've used. Seals quickly, you can see and hear where the puncture is and even works at high(ISH) pressures. It's easy for even the least mechanically minded person to use and install and the valve core tool in the lid is made of firm enough plastic to remove the core without grinding down. My wife has this in the tubes on her commute bike and hasn't had a flat in over 5 years. She loves it because she hates changing a tube by the side of the road and doesn't mind going a little slower. I won't touch it because it adds to rolling resistance, rotational weight and decreases the suppleness of the tyre, especially on corners. Basically, it'll slow you down by a few watts and I need all the help I can get. I also don't mind changing an inner tube on the rare occasion that I puncture.

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.

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

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.

Very good product

Purchased this after getting a series of punctures. Since then no problems and no punctures. Very easy to use with very clear instructions. It took no more than five minutes to fill and inflate both bike tyres. Cheaper and quicker than purchasing pre-filled inner tubes. UPDATE: I have used my pedal cycle thoughout the winter/spring on and off road. I have ridden on tracks after hedges have been cut and not yet had a puncture. I have checked the tyres and everything is okay. Either this is is a great product or I am totally lucky. I do not think it is my luck based on previous experience of getting punctures.
