Slime Smart Tube Self Healing 700c x 19-25 Presta Inner Tubes (Pack of 2)

Stops small punchers

Good but not as good as I remember used slime's for years then stopped cycling now restarted and they don't seem to last as long. Running 100 to 120 miles a week and having to pump every 2-3 days and only lasting a month. Going to try ever tire solid tire

Always used slime inner tubes. Well worth the price.

I had the tube in the tyre for approx. 4 days. Then got a puncture about 10 km from home.The tube deflated completely very quickly.I could not detect any evidence of the puncture self-repairing.I tried to pump up the tube but it would not hold pressure!!I had a spare tube with me which I fitted to the tyre and it got me home.Will not be buying this product again.A waste of money.

If you occasionally go through thorny roads, this product is for you. It repairs small punctures very well and allows you to drive comfortably. You can get efficiency from this product for a long time by checking the air pressure from time to time. As a note, if the sinking object is large and has caused a large wound on the tube, it is not possible to heal it. A repair system for minor sinkings only.

I have struggled with punctures on my road bike, so I have switched to Slime tubes. They have been great with 2 punctures in around 10,000 miles. I have been aware of punctures self healing, and with a top up of pressure have got home. The only downside is they are heavy, compared to standard tubes.

I will post an update when I get a puncture

This is my second pair of these bought because it was probably about time. The old pair had been on for about 1500 miles with no punctures until the rear one finally gave up when the tyre wore through and I thought I'd just change both. The tubes were both heavily punctured showing how well these work. I would have wasted quite a lot of time and 'normal' tubes if I'd had to fix them, not to mention been late to wherever I was going.I am really pleased with these. They don't actually cost a great deal more than a regular tube and I have noticed no difference in handling as a result of having them on. There is a bit of a weight difference but I carry only one spare tube (just in case) instead of two so it's probably offset for me.I am getting a new bike soon and these will be the first thing that goes on it as I wouldn't be without them.

Jan 8, 2021. So far I have used it one day, and it appears to be doing well.So speaking from conventional wisdom, the general concept is to not use tire sealant on road bikes because road bike tires do not have enough air volume to allow the sealant to do it's job before the tire runs out of air. However, if you have a CO2 cartridge pump in your tool bag, you can always refill it with air. This is much faster than the 15 minutes or so required to change an inner tube that has gone flat.

Purchased two inner tubes in preparation for a 720km trip. On day one hour zero one of the tubed was already busted behind the valve. Rotated the tyre, pumped it an it failed to seal. Had to install a different inner tube.1 hour, 20km later, the second tube failed in the second tire. IN THE SAME SPOT BEHIND THE VALVE.Two product failures on two different tyres, on the first use is a catastrophe.DO NOT BUY THIS.

Slime tube help prevent those annoying flats caused by small items.

This was my first experience with slime tubes, and it will be my last. Less than 2 weeks after I started using them, (approximately 150 miles of riding) I suffered a flat. Tried to re-inflate several times, but the air would still leak out, until finally, the slime actually came out of the presta valve. No thanks.

Great price for tubes that really do self seal quite effectively. Great protection against goatheads and such
