    • Works great

Super easy to install and has held up well in super rocky terrain and works great on my sons mountain bike

    • 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

    • 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

    • Initial Thoughts
Style: 27.5 Presta
I replaced a tire tube 3 times from one brand and was about to go to a professional and saw this so figured I'd give it a try. My initial issue with it was inflating it a little to get it in the tire. It wouldn't inflate, kept saying it was full. Well I messed with it and figured out I'd have to hold the tube in a specific way so that the "slime" wouldn't block the valve. That's pretty annoying but OK. Should be very clearly labeled somewhere that you need to do this though as I was about to send it back. ... show more

This innovative product has provided me with peace of mind during my cycling adventures, knowing that I have added protection against punctures and leaks. One of the standout features of the Slime Bike Inner Tube is its self-sealing properties. The tube is pre-filled with Slime, a special sealant that automatically seals punctures as they occur, preventing air from escaping and keeping my tires inflated. This has saved me from the hassle of dealing with flat tires while out on the road or trail. The installation of the Slime Bike Inner Tube was straightforward and hassle-free. It fit perfectly on my bike wheel, and I appreciated the added layer of protection it provided. The durable construction of the tube gives me confidence that it can withstand rough terrain and everyday use without compromising its performance. I have noticed a significant reduction in the number of punctures and flats since switching to the Slime Bike Inner Tube. The sealant inside the tube effectively seals small punctures caused by thorns, glass shards, or other debris, allowing me to continue my ride without interruption. Overall, I highly recommend the Slime Bike Inner Tube to cyclists looking for an effective and convenient solution to flat tires. It is a reliable product that delivers on its promise of added protection and peace of mind on the road or trail. With the Slime Bike Inner Tube, I can focus on enjoying my ride without worrying about unexpected punctures or leaks. ... show more

    • Keeps the tires going even if they get small punctures
Style: 26in Schrader
Living in AZ I would constantly get thorns spines and random junk piercing my tires but these kept them going. Its not an end all, big punctures will still end your ride but the small stuff will mostly be taken care of you just might need to pump up more often if this has been stopping up all the little stuff. Make sure you don't leave these in for super long-term storage though. I left them on a bike in storage for several years while I wasn't riding and when the rubber cracked from being old it was terrible mess to clean up. ... show more
