I commute year round, 7,000 miles per year. I do not want to deal with punctures, so I use these (paired with Schwalbe Marathons, also from Bike Tires Direct). I cannot remember the last time I had a flat with these, I do recall when replacing a tire the Slime tube being stuck inside, proving that the Slime tube did its job. The front MarathonSlime combo on my commuter has over 21,000 miles with zero punctures, and in total I estimate that the last puncture I had was somewhere around 45,000 miles. If you dont want to flat, get these!
I have used these tubes n y training bike, after having a three plate episode a few years back I decided I never wanted to walk 8 miles down hill in my cleats again! So I have been using slime tubes and they work great I never worry about running over stuff unless it is big stuff then I get worried.
I had one instance where a wire went through both sides of the tire and tube a very long wire and sharp.
Recently I had to replace a tube because the valve stem got stuck open but I had that tube on there for years, no complaints.
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.

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.
First of all, I'm completely comfortable changing tubes and tires along side the road. No issues for me to complete the task in 10 minutes or less. I just don't always leave myself enough time. Here is the problem, my commute involves a train and a 10 mile bike ride. I don't always leave myself enough time and if the wind is blowing the wrong direction, and I get a flat, I miss the train and I'm in for a much longer bike ride. The extra rotating mass from the slime isn't ideal, but it provides a little extra insurance if that glass or goat head decides to catch a ride in my tire. Its just good insurance and if I burn a few extra calories, all the better
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.
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.
Thanks for your review! I'm sorry to hear about the defective tube you received. Please don't hesitate to get in touch with our customer service department at [email protected] so we can make it right.
