Slime Lite Smart Tubes claim to be the lightest self-healing tubes on the planet, giving instant punctures seals up to 1/8″ (3 mm). Slime Lite Tubes combine a lightweight butyl tube with revolutionary sealant technology to provide flat protection without adding significant weight.

Ideal for winter training and commuting!

We offer these tubes in two sizes:
26x1.75/2.125 presta valve weighs only 219 grams
700x19/25 mm presta valve weighs only 117 grams

Don't take our word for how light and effective these tubes are here is what a couple of customers said:

"Pros: After 3 flats in 2 weeks while commuting to work, I switched to a combination of Slime Lite Smart Tubes and a set of flat resistant tires with a Kevlar belt. In over 1,000 miles of riding in the last 6 months I have had no flats and no problems with the tires or tubes. I run 700x28s @ 120 psi. The Lite Smart Tubes ride the same as a regular tube and are not significantly heavier. They are an excellent choice for commuters. Cons: The Presta valve Smart Tubes (currently) only come in a regular length Presta valve. If you have deep "V" rims like I do then airing the tube and checking pressure may require removal of the valve locknut or the addition of a valve extender. "

"Not one of those no flats in x months stories - I have proof that they work! I ride alot, was getting alot of flats, etc. so got new tires and Lite Slime tubes. To weeks later I got 2 thorns in my front tire - I pulled them out, heard the air hissing (obvious leaks) and saw the green slime in the thorn holes. I just started riding! They held for the next 9 miles (mtn bike on dirt), got very low near the end of the ride. I pumped them back up to 45 psi and they are still holding. I NEVER HAD TO PATCH! Been holding for 2 weeks now - about 150 miles. I'm sold, just bought another set of Slimers for my other bike. "
