Review: Work Well - I think these are good tubes, but overrated. The "no more flats" is certainly not true. But at the same time, they have worked well for me in about five thousand miles of riding. Here is my experience: They do get punctures the same way as regular tubes, but if you are moving along the puncture will partially seal. I also use very tough tires (Continental Gatorskin). You can see the green stuff ooze out at the site of the puncture before "sealing". On a recent occasion, my tire went completely flat at a very inconvenient location. I pumped it up instead of trying to replace the tube which I carry (not the slime type). I pumped and spun the tire as fast as possible; repeating several times. This got it up to maybe 60 psi which was good enough to ride back to my car some 30 miles away. When I got there, the tire was still rigid enough to continue riding on. But at home after a few days, the tire was down fairly low, although not completely flat. I replaced it at home, which is a lot easier than doing it on the road, especially since I find it difficult to take the tire off the rim due to arthritis in one of my hands. Another problem I encountered is that the green goo clogs the valve making it hard to inflate the tire when it is low. I take care of pressure before leaving home. I found that if you let out some air the green goo is flushed out of the valve. Then you can re-inflate the tire more easily. I would not recommend risking inflating the tire after you have arrived at your starting destination. Let me say a little more about the flat tire problems on road bikes. I found that the aforementioned Gatorskin tires take care of most of the puncture problems. They resist all the big stuff like small nails and glass shards. What gets through them is fine wiry debris that is left from shards of shredded steel belted tires that are on the road side. In almost all my flats, that's what I found. These wires get through the kevlar and cannot be seen or removed from the outside. Hence requiring a removal of the tube before the tire can be cleared and restored. No tube will seal itself permanently in this situation. So, if you use the puncture resistant tires, these tubes will essentially get you home, but you still have to replace them. For me, that is worth it, so I am giving it 5 stars. I know riders who change tubes out in 5 minutes - for them it is not worth it because these tubes are heavy and expensive. Addendum: After I wrote the review, I had another flat with these tubes. The tire went completely flat after about 50 miles of riding. It was pumped up at the start to 80 psi. I was not far from the end, so I pumped it up and it held for the next 1/2 hr of riding. It still had good pressure, but the next day it was flat. Upon examining the tube at home, there was a small hole in it. It did not seal, or whatever the mechanics was, it is not able to seal to give you more rides as long as the cause is not fixed. Then you can patch it up as you would any other tube, but I just throw the punctured ones out because they can never be relied on. I am still using these, because they are better than normal tubes for my circumstances and needs.
Review: Yes They Work and Are Worth It! - I ride about 6000 miles a year for several years, all in an urban environment in and around NYC. I've tried all different tire types (gravel, gatorskin, 23-32mm, etc). I've tried all different types of tubes (pre filled anti puncture, manually filled anti puncture, no anti puncture liquid, etc). I've had my share of flats. All that being said, these do work pretty well. I've never had an overnight flat or a slow leak flat when they are installed. What I have encountered is catastrophic instant flats with them. So they do seem to prevent small hole/leak flats, but they're not going to stop a hole that is even a few mm wide. They are a bit of a pain to install and take a little practice. The 700s I got always seem to be a bit bigger than the wheel and sometimes it is a pain to get them to fit properly depending on the tire you use. Pros -Slow leak and overnight flats don't happen -If you get a small puncture you'll probably get home Cons -Not easy to install -Cost more than normal tubes Bottom line to me is that if they stop even one slow leak flat in their lifetime it is worth the extra cost and hassle to install.
