Slime Bike Inner Tube with Slime Puncture Sealant

I am a real person who does not review often. This product has done me well. I tried it on one of my tires 2+ years ago, so when i popped the regular tube in my other tire, this was a no brainer. However, this tube got flat within a year. HOWEVER, I called the manufacturer and their CUSTOMER SERVICE was STELLAR! They called back and texted! They had me verify purchase and sent out a replacement. I couldn't be happier. Don't trust any other review that slams the product or company. This is for real. OK, gotta go get on a bike and ride, now! THANK YOU SLIME!

I have switched to these on my gravel bike. They aren't amazing or anything but they are better than not having it if you ask me. I'm not huge on shedding weight on my bike, though - they are much heavier than a normal tube.

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.

Out of the box:Good: rubber is not the worst I've seen, I'd add more talс, it pretty dryGood: green valve cap look cool, it has the stem extraction tread on the other sideBad: you would never be able to unscrew stem valve with that plastic capBad: think 5 times before inflating, if you will deflate, green slime will make your stem valve leaking, so see above, you'd need a real tool to take off the stem valve, clean it and put it backI didn't do jumping tests on it, will update, so far looks solid on city drive without anything above it

Put bike in the basement over the winter. While setting up for this summer both tires needed air. The front tires schrader fitting came out of tube and the rear was leaking at the fitting. Reached out to SLIME customer support and they asked a few questions and sent me replacement tubes at no additional cost to me. Really outstanding customer support from SLIME. Highly recommend these products. Even though I had a problem, they resolved it very fast and professionally.

Shipped quickly, reasonably priced, appears to be a quality product
