Slime Lite Smart Tube self-healing tubes instantly seal punctures up to 1/8" (3mm). Slime Lite Tubes combine a lightweight butyl tube with revolutionary sealant technology to provide flat protection without adding significant weight.
Since the sealant is already added, there is no need to go through the messy and time-consuming process of trying to inject sealant through the valve stem. Great choice for commuters, cross racers or any rider who wants an extra measure of protection from punctures. Select 700 x 19-25mm or 700 x 28-35mm.
Had two of these tubes blow out at the valve stem. Even when they weren't pumping green slime all over my bike they didn't stop punctures and I'm talking about small, thorn size. Not anything big.
Cons: Poor quality
riding west of Las Vegas, the partner flatted after pulling off the shoulder of the highway. Replaced the tube with the slime lite after pulling out a big-ish thorn. Rode home with her gradually loosing pressure in the other tire, which was also effected. fixed that with a regular tube after going over the tires, which seemed to have a bunch of the little thorns/prickles/whatever (we were visiting Canadians and didn't understand the desert vegetation hazards). A few weeks and more rides on now, and the slime tube soldiers on impervious, whilst the other tire keeps finding more sharp bits to deflate whichever tube we put in there. I'll seek them out again.
Pros: work better
Cons: garish green valve stem cap you should throw away
I have bought 2 of these and won't buy anymore. both of them have gone flat and would not reinflate, I think the problem is in the stem. Today the second one went flat when I ran over a tack. I tried to inflate it but it did not work. They are pricey and have not lived up to the promise of sealing leaks.
Cons: Don't seal leaks, Heavy
