SlimeSelf-Sealing Presta Tubes(Return to Product Page)

I have a beltdrive and getting my rear wheel out is just a little more time consuming. So this is just another layer of protection to avoid flats. I use it on my raincommutergravel bike.

My wife and I use these tubes on our daily commuter bikes. And after a year of service she got a flat. Upon closer inspection the tube actually had 7 punctures that sealed. Ironically, this last one sealed too and she was able to get home safely.

I ride because it is part of my physical therapy regiment. I have back, leg, and foot issues and after my latest diagnoses, I can only ride a bike (and I used to hike, walk, and jog but can't because of health reasons) I have been using Slime tubes for years and had a pretty good supply stocked up. I understand that were I live I will occasionally get a flat that is why I carry the necessary extra tubes and a pump on all of my rides. Something must have happened because the last time I stocked up I must have received a defective batch or something because I have had to replace 4 flats in the last two weeks. One ride last week took me two hours to travel three miles....why, because I had to replace two tubes on the same tire on the same trip. You might think flat, no big deal...with back and leg problems, pushing home a bike makes worse my condition and the last time I ended up staying in bed for a whole day and missing work as a result. I used to think Slime was wonderful, but now not so much...especially since the last flat was result of a tube split on a seam which was on the rim side of the tube. This screams obvious defect and poor quality of workmanship (well at least on this last batch). Definitely going to Slime.com and tell them what's what. Four times I've had to replace flat tubes that refused to hold any air. I'm not a rocket scientist but if this isn't a result of a bad batch and represents just a single incident, we'll see, but if this is the new normal for slime tubes, it's obvious that they are a waste of money, time, and my health...too bad, they used to make a wonderful product.

Great tube, easier to. Install than I expected with the slime in it. I ride over a section of path that has lot's of Clam shell's dropped by Seagull's I no longer have a fear of flatting. Also, Before getting the slime tube's I carried a saddle bag with a couple of regular tube's, co2, tire lever's. Now I don't carry anything.

8 miles into the first ride on these tubes I had a flat. When I took the tube out it had split at the seam. Failure was not due to puncture. I�d bought a second one so I put the 2nd one in and have been riding on that one. 150 miles in on the second one with no issues.

I've used these for years on my mtb. Work great, I've had two flats with these, not enough air/time to self seal and the slime makes a patch not feasible. They are also pretty heavy compared to normal tires. The green valve caps are cool though

Pure garbage! I ordered about 4-6 of these and on nearly all the presta valved stem separated from the tube after about 5 minutes of riding. Think one or two held up but the rest failed quickly. Additionally, there's not a whole lot of slime in the tube either......just enough to call it a slime tube and enough to cover your thumb nail when the valve stem breaks off after you look at it wrong. Super-duper fragile.

I did not have any problem installing and using, they seem to be considerably strong and may resist some puncture from rust, I like them.

The tubes seem heavy. I use it on my commuting bike (would hate to get a flat on the way to work) but would NOT use it on my touring steed.

It's easy, the slime is already in the tube. This is absolutely great if you ride in a place with goat head stickers, you can usually pull them out and keep riding I put them on my wife's bike as she doesn't take a pump or know how to fix a flat yet.

Probably nothing wrong with the tubes and maybe I didn't study the instructions close enough; BUT, when I used the air pressure gage on it goop came out through the valve and clogged up my gage. (My tubes were Schrader valves) Gave them to a friend who didn't care since he just thumps his tires when checking pressure. If I become a thumper I would try them again, but otherwise I'll stay with non goop tubes.

I have been using slime tubes for various application for about 7 years. They have been good at sealing goat head thorn punctures and small wire but still require re-inflation. Larger debris and glass will require a patch. Out of the past 2 I bought, one had a valve stem failure out of the box but I didn't realize until after installed so I couldn't return. Similar quality issues with the slime products over the past 6 months has me looking for other alternatives on bicycles I change tires on for various conditions (hence, the tubeless option is out)

I installed this inner tube on the rear wheel of my mountain bike. In 25 years of riding, I've had many flat rear tires, but only about 2 or 3 flats on the front. It must be because of the higher weight distribution to the rear wheel. I'm hoping the slime in the tube will seal any flats, but don't have any yet. So far this year, I've only been commuting about 25 miles tofrom work on regular asphalt roads.

both 26 inch tubes are bad out of the box the first one leaked around the valve the second one blew up when inflated to 40 pounds complete waste of time and money.

No mess is nice but they are a bit pricey. They work great for small punctures and always get me home!

Is there anything more frustrating than changing tubes mid-ride? Not for me. This is a great product that got me through the last 16 miles of the bike on my recent 70.3 when I picked up a tack but was able to finish the race.

I have used Slime tubes for years with great success. I have ridden in thorn and cactus infested areas for hundreds of thousands of mile. Not to mention the hundreds of small sealups,I once had a gnarly 4 inch thorn go thru the tread and out the sidewall, I pulled it out spun the tire and watched the green wonder goo seal it up. I never changed that tube until the tire went bald, several hundred miles later.

I was dissapointed though when this last tube I used separated at the stem rubber connection at initial fillup. Too much of a pain in the ass to send it back so I ate it.

Even given that, these tubes are worth their weight in thorns.

I use the slime tubes on my mountain bike and they work great. I decided to buy these for my road bike for training to minimize the possibility of a tube swap during a ride. These tubes do hold up and will typically allow you to finish a ride before the leak forces a tube swap. I did get a pinched tube with one of these and it did not stop the leak, so for that reason I gave 4 stars.

These tubes are great. We live in an area where there are tons of thorns. I did nothing but patch tires. Haven't had to do one repair since putting these on.
