    • Great!
Style: 24in Schrader
Came very quick and was nice and easy for my husband to install which my bike loving 7 year old appreciated so he could get back to riding! Tube has held up great and haven’t had to use another one or add any more air since I ordered 6 months ago and my kiddo is a rough and tumble boy who rides hard. Would absolutely recommend. ... show more

    • Works great; no more flat tires
Style: 700 X 28-35mm Presta
Swapped my inner tubes out for these and I have no more leaks on my tires. No complaints, no issues, and it was simple to install.

    • Excellent Customer Service and Excellent Product
Style: 700 X 19-25mm Presta
Post post script: This is an excellent product and company! The tubes are excellent performers and the company is super responsive for orders, any issues, and customer service. HIGHLY recommend! Post script: As soon as I wrote re the bad tire (out of the box), Slime Co. immediately sent a replacement. Well done! Additionally, the Slime tubes I've installed for my road bike, so far so good. I highly endorse this product and company. Bravo. Ordered a four pack and the first one upon inflation exploded with green goop all over the place. Had a sizeable tear right out of the box. Installed another of four on my road bike and so far, so good (prayers appreciated). I requested Slime send at least one replacement and standing by to hear...so this is not a negative or positive review, yet, and provides benefit of the doubt until I head from Slime and gauge performance of the one tube I've installed. ... show more

Style: 27.5 Presta
The Slime Bike Inner Tube has garnered attention for its innovative approach to tackling the age-old problem of flat tires. Here’s a detailed review highlighting the positives and negatives that we have seen while using it on mountain bikes: Self-Sealing Convenience The tube’s self-sealing capability. It effectively seals punctures up to 3mm, ensuring that your ride isn’t halted by unexpected flats. Durability and Protection There has been a significant reduction in punctures for my son, but it hasn't been as good as riding a tubeless setup. He is hard on his stuff, so this has saved me money until he can take better care of his bike. Weight Consideration The added weight due to the sealant is a notable downside. It can slow you down, especially if speed is a crucial factor in your cycling activities, but my son isn't a pro racer so the reliability of it proves to be more important for us right now. Ease of Installation Installation is straightforward, and you don't have to do anything different than standard inner tubes, which means you won’t be fiddling around with complicated procedures. Overall, the Slime Bike Inner Tube offers peace of mind for those looking to minimize puncture-related interruptions. While it may add some weight to your ride, the trade-off could be worth it for the added protection and convenience. If you’re a commuter or casual cyclist, this could be a game-changer for you. However, speed enthusiasts might find the weight increase a deal-breaker. ... show more

    • Work Well
Style: 700 X 19-25mm Presta
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. ... show more

Tried many tubes in my mountain bike - this one works - it far outlasts all the others I tried.
