Just Awful!
I have used slime liners for years and thought they made good stuff...freshening up the bike I thought instead of liners I'd use these as a one-two punch with a new set of Continental Gatorskins. First one installed ok, but the second one ... while it seemed to hold air started leaking slime. I decided to remove it to inspect and could not get air to release thru the presta valve! By the time I got it off the wheel it was a total slimy mess ... right to the trash it went. I'll leave the good one on for now, but I can not imagine having to work with this tube while out on the road. I don't usually pan products, but this is pretty bad.
heavy, but no flats so far!
I rarely get flats, but after two flats in one week I grabbed one of these tubes. I do like that it works, and provides a theory of peace-of-mind regarding future flats. I don't like the slime and winter cold working together to off-balance the heavier-than-normal tube. It seems to ride ok, but maintenance where spinning the tire is needed requires extra steadying so the bike doesn't jump off the stand. Overall I feel it is a great product, but the added weight and balance feels will probably keep me running a lightweight tube and carrying a spare with my multitool for the future. At least on 40mm and less tire widths.
They work for me, but are hard to patch
Slime tubes really do work. I have pulled out dozens of goat-heads (spikey plant seeds) from my tires. Most of the time the sealant works by itself. Sometimes I have to spin the wheel to get the slime to fill in the hole. But then I pump up the tube and I am ready to roll again. However, it is not perfect. And when I do get a puncture that does not self-heal it is extremely hard to patch. The slime gets everywhere and interferes with the glue. So every year or so I have to buy a new tube. I use them to commute and for mountain biking.
Corrosive to valve parts
My experience with Slime tubes and Slime used in other brand tubes is that the Slime corrodes parts of the valve and/or glues them together, so the Presta valve stem locknut can't be unscrewed without pliers or a wrench, and once unscrewed, the valve will never seal again. The Slime does work to seal small punctures, but you still have to top up the air periodically and often even more after a leak. If the valve stem itself can be unscrewed without breaking something, you can sometimes clean off the gunk and flush the valve tube with hot water and restore the ability to unscrew the locknut, but this is a temporary fix and more trouble than it's worth.
Don't trust other reviews
These guys are obviously using Slime tubes with skinny race tires. I commute everyday with Slime and Panaracer T-Serv my last tubes lasted 4200 miles(2 yrs). Combine with Kevlar tires and you have a dependable commuter set up that will get you where you need to go 99% of the time. The only con I have is that the valves corrode sealed over time because you never have to change them. Lycra roadies need to stick to your liteweight tubes and pizza cutters, and just keep on changing flats. Hey it happens, deal with it.
Bike Messenger review.
I work as a bike messenger in nyc and these tubes coupled with my gatorskins and I have gone more than a year without getting a flat. In fact, the tire itself wore out and flaked before the tube. The one downside is that if you need to unscrew and discharge your presta, a bit of the goo will squirt out. It gets sticky and makes it hard to unscrew. No big deal, but take note.
Good idea
This will cut down on the number of possible tube punctures, but will not seal all puncture one might get. It has cut down by half the number of times I've had to patch a tube. Regular tube patches will work on this tube, but you have to be sure to clean the green slime off before attempting to patch a hole.
still solid after a year of use
Odd that the reviews thrash this product. I’ve had them on for a year and haven’t had a single flat. I’m going to buy an extra one to keep handy so when the days comes it will be an easy swap out. They probably are a bit heavier but that’s fine considering I was getting a flat every 1-2 weeks with standard tubes. It was driving me crazy.
When slime is a good thing
I ride my hybrid bike 2-3 times a week, 15 to 20 miles per ride. About 2/3 of my ride is in bike lanes. There's lots of glass, thorns, etc. to make life interesting. The slime tires have extended my innertube life. I still get flats but much less often.
Slime is dangerous and useless.
Not only does slime not prevent flats but it is so slippery that when it leaks out of the tube, the tire can immediately come off the rim and you can crash (as I found out). I was involved in testing slime for the company I worked for since the company sold all kinds of flat prevention products. It was found that slime was the least effective of any product available for preventing flats as well as the discovered safety issue. I will never use anything with slime again.
