Slime Extra Strong Self-Sealing Bicycle Tube Presta 700 x 19-25mm Bike Inner Tube - 30085

Cheapest presta slimed tubes I could find.

i live in a city where people have no regard for a clean environment, ie i run over glass constsntly. When i spend a few dollars more on any Slime product, the savings i get because i replace slime products a lot less often, saves me time and money. SLIME IS AWESOME!

Great product, saves time instead of putting slime in tube yourself. WM assoc.

I use these all the time, only bought this one because I needed a spare tube. Usually pay half the cost, just out of stock.

It was easy to install, and has been holding air pressure!

Works like a charm. Gets me home. Flats from thorns are a thing of the past.

The slime does it thing but also like to clog up the valve stem.

These things pop a hole and covered my front tire with slime and now my skin is all drid up and made a huge mess on my carpet what a waste of a dime...!!!

Tubes just don't hold up to daily use. I had used one of these tubes about a year earlier and it seemed fine so I bought 3 more... my bad:( None of the new tubes lasted even a week of use on paved roads. I checked for tube punctures but found none - all used with new tires and Mr. Tuffy Bicycle Tire Liners and all tubes failed suddenly during rides. I tripple checked the inside and outside of the tires, rims and there were no punctures. I even triple checked that the tube was exactly the correct size and no twisting or pinching of the tube when installed. I've installed over a thousand tubes and these are simply terrible. Couldn't get my money back because it was over 90 days. Looks like these were simply lacking any quality control as there were imperfections in the thickness of the rubber in different areas leading to failures. Bought standard Schrader valve tubes and am much happier.

The first time I went out on the bike and it gets a flat. no glass or nail. just the air just left
