It was designed to reduce flats. 48mm Presta Valve, Threaded with a Core. If you have an old inner tube, please check the side of it for the correct valve size and length. Adding a little air to the tube is a must when changing your bicycle inner tube. This gives it form so it doesn't get twisted or bunch up. Once the new tube is installed and fully inflated, only add a few PSI to form the tube. You should be able to see an even bead of the tire on both sides. Re- inspect the tire bead to the rim after inflating to half the desired PSI. inflate to the recommended air pressure if the beading is all the way around on both sides. If the bead doesn't hook properly on the rim, the inner tube can slip out between the tire and rim and then explode.
👤Most of the negative reviews for these tubes are because the 60mm valve length is not threaded. The 32mm and 48mm stems are threaded, the 60mm is not. A standard weight tube is less expensive than most other brands. If you get lucky, your local bike shop will sell the Specialized brand tubes for $8. The Street Fit tubes are made by Sunlite, a good maker of inner tubes, and they cost me less than $6 per tube in the value pack. I think that's a good deal. I have no issues with mine and I will keep buying the cheaper tubes until I see a reason to switch.
👤The tubes blow in every instance. I have ridden less than 10 miles on three sets of tubes. The tubes blow close to the valve. I am assuming that the machine used to hold the tube produces a round that punctures the tube. I thought I had done something wrong two times, but three times is the charm. I only rode this bike once after putting the newest tubes in. I put it on the road. When I hit 80 pounds, the tube blew. Wow, given that it's rated at 112... It was a big let down. I will not recommend these tubes to anyone.
👤I can't recommend these brands. Bike tubes are the type of thing you buy and they sit on the shelf until you need them, but they turned out to be unreliable. One of the tubes was installed a year ago. Since the tube was installed, the bike is rarely used. It was used four days ago and got a flat. There is a It wasn't a puncture. A hole was created where the stem meets the tube. The location made it impossible to patch. These things happen again. I filled the 2nd tube to 1/3rds pressure after installing it. All was fine when I checked it the next morning. The bike has not been used since the 2nd tube was installed. I was expecting it to be a problem at the stem/tube connection. It was not. The tube split. There was a small separation on the rim side of the tube. It could not be patched because of the location.
👤Three of the four Sunlite tubes that I bought in the last month have failed. I'll give that one the benefit of the doubt, but it could've been a pinch flat/install error. The valve stem core failed in the same way as the other two. I will replace with any other brand if the fourth one fails this week. Look elsewhere? If you can! This is not the fault of Amazon or the seller, the price was good and shipping was good.
Made heavy duty from quality materials. They do it right by making dependable and durable inner tubes. Count on it! High pressure blow outs are prevented by mold cured rubber. The inner tube was reliably tested. 35mm with cap is the valve type. It's great for Mountain bike tires.
👤The gum walls of my 1981 Schwinn LeTour were starting to crack after decades in storage. The tubes were ordered about 3 years ago. It never held air over night after it was installed. The other tire and tube can be put in the original packaging. I checked the tube with soap water after dismounting the first tire. I decided to change the other tire and tube while I was at it. It was flat to 90 PSI per the spec. The seam blew about 5 inches. Where can I buy quality inner tubes? Been on wheelbarrows, bikes, lawn tractor, etc. In the past few years, there have been many times. Either the whole seam blows or it keeps tearing at the seam a little at a time. When I dismounted the tire of my plane in 2010, I found an original 1940 inner tube from my Stearman that had been patched 14 times and was still flying. I still have it as a souvenir, even though I replaced it. NotRECOMMENDED.
👤It's not worth replacing a cheap price when it breaks. Go for a little expensive one, this is the last few days for me, now I have an order for a new one. There is a When you are riding away from home, there is an additional hassle.
👤I bought this tube for my bike. I can't say that it works. It was easy to do and held air for over a month. That seems good to me. I put between 60-90 pounds of air in the tires. I bought a bike tube. My tire was small. There were no issues with the tube in the tire. I can't comment on "durability" since it's only been a month.
👤I thought it was a high quality tube. It exploded when I tried to blow it up. I used the tires recommendation of 102 pounds because there was no instructions on the box. It popped when I reached 80 pounds. I had a tube blow up for the first time in my 20 years of bike riding. You should spend a little more money and get a tube. I was not on the bike when it happened. You should take your chances if you buy one of these tubes.
👤These are so cheap that I was skeptical about them. I can tell after a year on these that they are the same as any other tube. Tubes won't help you avoid flat tires. I had a flat tire all the time. No more flats after I installed good tire liners. My friend bought expensive puncture proof tires and got few flats while riding the same distance. If you want to avoid flat tires, you can save some money by buying tire liners instead of the tubes.
Designed to seal punctures. There are 4 Continental Inner Tubes.
👤These tubes are good value. The box says 32-47c tires. These are thin-wall tubes that would be acceptable for 32-38c tires, but I wouldn't venture higher than 38c. I own a Trek Verve 1 with 45c tires. I flattened all three of them in a single month, doing nothing different in either my tire-mounting process or biking method. The problem is that these are too thin-walled to work in the bigger space and air-volume space of a 40c or 45c tire, they can expand in size too big, and then pop. There is a The amount of air-volume space in your tire is what you need a heavy-duty, thick walled tube for. The Sunlite 40-45c tubes are heavy duty and will hold 65psi.
👤The tubes are made in Germany according to the website. There is a The box hints that they are made in Germany. There is no "made in" sentence on the box, but all of the printing on the box refers to Germany. There is a The inner tube is made in China. Changed from 1 to 3 stars. I bought 8 of them. They were wrapped in two packages. There is a The boxes were faded as if they were left out in the sun, and some of the print could not be read. There is a The other pack of four looked like it was fresh from the factory. I've used my tube for 30 years and never get more than one year out. I don't think there will be any more out of these tubes.
👤I got back into cycling on paved paths 3-4 times a week. The original front tube of my Gary Fisher hybrid bike was not holding air for rides, so I bought a pack of four. It was good to get 10 years use out of an inner tube. There is a After installing a new Continental tube, the tube stayed full for a few days. If you check the pressure before each ride, only a small amount would be lost, which is not an issue for a tire that takes 60-80 lbs of pressure. You should always check tire pressure before riding. The quality of these tubes is high and the price is acceptable for me. Happy with the performance so far.
👤I had no issues with getting them installed and inflated up to 55 psi, it was a great tube for the price. There is a The stems are made of metal and have a washer that keeps the stem in place. I always hated on my old tubes when I wanted to add air, or if it went flat while out riding the tube, it would spin in the rim and be a pain to get it centered. I've had tubes get holes around the stem or have the stem torn off from excessive flexing, so this is a huge pro for me. Time will tell how long these new tubes will last. I'm nervous to see what kind of life span they may have. Will update if there are any issues.
Replacement inner tube for a hybrid, fitness, comfort bike or other bicycle with the same tire size. The claimed weight is 105g, and the wheel size is 700x20/25. Excellent replacement inner tube for your road bike. Butyl tubes have Continental quality. Every inner tube passes a 100% quality control inspection. To ensure uniform roundness and a smooth ride, a seamless construction with a mould-cured vulcanisation is used.
👤I recall why I haven't used continental tubes in a while. The tubes are poorly made. The valve cores came undone multiple times during the install. It comes in a 5 pack and you can only have one or two that can hold air. After the installation was complete, I had 3 pop. I under- inflated my pressure, using 80psi instead of the recommended 100-120psi. I cleaned the rim and inspected it for any defects, but I didn't have any tools to puncture the tubes, so I popped 3 of them before I could even ride the bike. My wife and I popped a 4th tube on a ride around the neighborhood. The 5th was thrown away. I bought a new set from a local shop and have not had any issues since. Buy anything else if you don't want to be frustrated.
👤The valve cores are weak. When you remove the cap, the valve core can come loose, blowing all of the remaining pressure out. It's not a good idea to remove the protective cap every time you try to top up the air in your tube. Three of the five tubes were tried by me. The other two will as well. Don't be frustrated and stay away.
👤I have a favorable opinion of Continental products. Their tires are the best. I have gone months without a flat or puncture while using them. I also bought the inner tubes when I put on the new Gatorskin tires. The five are in the trash because of flats. There were no punctures, just one flat after another due to the holes in the inner tubes. I went to a local bike shop and found a brand that had a thicker tube. The flats stopped moving. They are still happy with their tires. I was a bit puzzled by what happened with these tubes.
👤I don't know if these are cheap Chinese imitations, or if they've been sitting in a warehouse somewhere for the last decade, but these tubes are complete garbage. If you don't mount them, you'll see bulges and flaws where the wall thickness of the tube varies greatly. I used 4 tubes to go 6 miles if I mounted them. It took me 2 hours to ride 6 miles because each tube I mounted in my tires had a small hole that would deflate within a half mile. It took me 4 tires before I mounted a bike that didn't have a puncture. 3 of the holes were on the inside of the tube and 2 of them were at the seat of the valve stem. Each time my tire and rim were checked, they found debris. I spent 2 hours and $30 on this trash. Don't buy these from your local store, just buy some good tubes from there.
China is the country of origin. Tubes have a mold-cured vulcanization to ensure uniform roundness. The construction was Threaded with a Valve Core. Factory packaging contains 4 Continental Inner Tubes.
👤I noticed several negative reviews before I bought these inner tubes. I put one in my bike tire and it burst and deflated. I tried a second one with the same result. I had a Bontrager tube that lasted me for 10 years and I would pump it up to 80psi. There is a I wrote this review because I don't want someone to be taking a long bike ride, encounter a flat tire, install one of these tubes, have it burst, and be left stranded out in the wilderness. This is not a good brand. Don't let your personal safety be jeopardized by this product.
👤I use these tubes on my gravel bike and the Conti's are the best. I put latex in my gravel tubes so they don't flats. I had a tube for a full season. When you can find a deal on a pack like this, go for it.
👤Finding quality inner tubes was difficult for me since I ride a hybrid bike and have an odd tire. There is a I have had no issues with their tubes popping right away. I kept two of these in my bag when I rode my bike 14 miles to work. I ran over the metal wire that peirced my inner tube. I learned how to install an inner tube myself at work at 1AM, and it continued until I bought myself larger tires. I'm not an inner tube expert, but these seem thick and sturdy, just as I would expect from a good brand name. I didn't have any issues with the valve stem. I would buy this again. I haven't had a fail on me yet, so I might not have to.
👤I thought it would be smart to install new tubes while I was stalling the new tires. I traveled over 200 miles on the Katy trail.
👤I can't find 700 x 37c tires online, but these are the only ones I can find. I've had inner tubes pop off when I remove the cap to air them up. At least 8 have done this. They pop very easily. I have to carry 4 extra tubes with me to work because these are so bad. I can't find any other brand tubes for my bike. I would go without a tube, but it would cost me 400 dollars. It's almost worth it because I'm buying so many of these pieces. Don't buy these if you can find other tubes that work for your bike. These are definitely not speculative. The worst dinner. TUBES. I have used a lot in my life. I can't find a different brand. The valves keep popping off. I have to air my tires at least 3 times a week to keep them at pressure.
High butyl rubber has better airtightness, heat resistance, and durability. Dust is prevented from entering by using a highly airtight nozzle. The Continental Cross 700x32-47c Bicycle Inner Tube Bundle is a 4 pack. The construction was Threaded with a Valve Core. The weight is 170g per tube.
👤So your first thought is, how much, but I bet that extra $1-2 is worth every penny. When you pick these up, the first thought is that they have a better feel to them, the rubber seems thicker and higher quality, than the budget ones you picked up previously, but probably not worth fretting about. The inner tubes hold the air better than other brands, which makes you think they are better made. I used to pump tire every 3 days, but now do it once a week and leave in 2 weeks. I don't know how well they repair, but the inner tube they replaced was covered in patches, that's a good sign. I replaced the tire at the same time. I've had no complaints from my wife, who's bike they are fitted to.
👤The stem of the valve can be secured to the rim of the wheel with the help of a washer. The tip of the valve is not something I like. If you use a CO2 cartridge to reinflate, the part of the valve that screws on will get stuck, and the tip of the valve will come off when you remove it. You will have used an entire CO2 cartridge. This happened to me many times. This is not good. I would avoid them.
👤I wanted to write this review because when I was looking to purchase inner tubes, there were many horror story reviews of them exploding. I have found these tubes to be very good. The presta valves are well constructed and installed. The caps are tightened at the end. They hold pressure for a while. I check them every three days or so and they only lose a small amount from 60 and 65psi. Excellent inner tubes. I highly recommend them. There is a I used to purchase tubes from a major bike manufacturer. They were not as good as the tubes. The presta valve assembly came loose on two occasions. The dust caps seemed to be stripped. These are superb inner tubes and you should not believe the hype of the bad reviews. I highly recommend them.
👤When I had a flat tire, I replaced the tube because of the size difference. The Tubes seem to be a little large and had some difficulty in getting all the tube in, in fact on my first attempt I noticed where the excess tube would put pressure in the area where the lap was over. It worked well, but had to remove the air and adjust the inner tube until it no longer pushed the rubber tire out.
It's great for road bike tires. These are not normal bicycle tubes. The inner tubes are strong enough to stop flats for 2 years. Fibro-Seal Technology makes it possible to instantly seal punctures in your tubes up to 3mm. Designed to stop tube punctures from ruining your ride. The Presta Valve tube installs like any traditional inner tube. It is environmentally friendly. Water is non-toxic, non-corrosive and non-flammable.
👤I bought two of these tubes to not have to replace them in the future. I didn't ride my bike for a couple days after installing them. The front tire was flat when I arrived at the garage. I took the tube off the bike to look at it, and I found green slime leaking out of a dime-sized hole, and also slime leaking out of the base of the valve stem. This looks like a defect to me. I wouldn't buy this tube again. I inflated it to 45psi per my tire's specification.
👤These were bought because of the stickers that are blown around in Afghanistan. I wasn't going off-road just because the parking lot was there. I lost both tires in a week. They had 7 holes patched. Both were flat within three days. I decided to get the self seal because inner tubes are a commodity here in Bagram. They were in about 10 days. They were installed and have been free for two months. I find the occasional thorn/thicket/sticker in the tire, pull it out and keep on rolling. Thanks for the product that saved me from walking all over this base.
👤These tubes are heavy. Know that weight is a factor. The rubber in the "tread area" is very thick and there is a lot of sealant inside. You must not pinch the tube when you install a tube tire. If you don't do it right, you will end up blaming the tube, and I don't care how good you are. You have to follow the proper procedure to remove the valve stem. If you don't have tire spoons, a couple small box end wrenches are the best substitute. If you're not careful with any tube, you will probably pinch it and it won't hold air. Make sure that the valve stem is aligned with the wheel before inflating, and that the tube is not twisted. If something is not right with the installation it will probably damage the tube or not work right because it is so thick. If you release pressure through the valve, it will plug up with the sealant. This doesn't ruin the tube. The green valve stem caps are reversable, and the reverse side is a valve core removal tool. Remove the valve core and clean it, then replace it. Park wheel with valve near top of wheel and let sit for a few minutes before adjusting pressure to avoid clogging valve.
Premium inner tube is a high-quality butyl rubber compound which results in fewer flats, longer lasting and durable. Quality was tested. A 24 hour inflation test is included in the 100% quality control inspection. 6 per pack If you are not completely satisfied with your purchase, VeloTubes will give you a full refund. Each 700C X 18/25 Grams is 120 Grams. 48mm Presta Valve is fixed.
👤Since one of my riding buddies shared it, I came across it. I have installed one in my saddle bag, but I also have another one in my bag. I inflated these before installing and didn't notice any problems as others reported. I was able to inflate my tire to 100psi and have been riding it for a month. I will report back if I see something new. Happy riding! There is a There is a new update on July 7, 2019. I used another tube from the set that I got, but this one didn't last a day and had a puncture. I only faced an issue with this one, out of the 3 that I used. I patched it up. We will see how that goes. There is a * If you find my review helpful, please click the 'Yes' in the review. I keep sharing more experiences with the community.
👤I have never had a failure with this pack of tubes. I was frustrated and left a negative review after 3 out of 6 of the tubes I received were found to be faulty. The seller went out of his way to send me a new set of tubes with a hand written apology and I have ordered around 10 or so 6 packs for use by myself. I didn't ask the seller to send me replacement tubes or even let him know they had failed, he took the initiative himself. I think that speaks volumes for this seller and have no problem with a positive review because I am confident that the buyer will get a great value and be treated fairly in the rare event of a defect. 5 stars It is forever.
👤I ride a road bike. I like the idea of a tube that is light. The Continental Race or Light tubes are very thin. They fail more often than standard tubes. There is a The generic tubes are not too heavy and are thick at 121.75g. They are inexpensive.
👤I have ordered these many times and had no issues. Make sure you get the right size for your application. When the tube is inside a tire, inflate fully. People getting punctures were some of the issues I saw. I don't understand how that's the sellers fault.
👤I should have listened to the reviews that said the tubes were bad. I realized after getting 3 flats that every single tube had a defect opposite the valve stem. When you pump these tubes up with no tire, this area is more restricted than with normal tubes, which probably has something to do with the leaks. There is a The nature of the defect makes it difficult to patch. Not a single tube held air for more than a day, so I am hoping for a refund. I was stranded 10 miles from home twice. Stay away from them.
Practical warning lights. The Led flash valve cap light can illuminate your tires in the dark, but it can also warn the surrounding pedestrians and cars. The safety of you and others is assured. Continental Race Light 700x20-25c Bicycle Inner Tubes - 80mm Long Presta Valve - 5 Pack. The construction was Threaded with a Valve Core. The weight: The tube has 82g per it. Road racing is intended use.
👤I need 80mm valve stems for my deep set rims. These are about 75mm. The Valve Stems are not Threaded. So. There is no other way to get the STEM to the rim. It's nearly impossible to change the pump to the grapevine because it's so hard to get the grapevine to open. They are not durable and are very thin. 2 tubes were lost during installation because they were pinched by a plastic lever. This type of puncture should not have happened because I was not using full power or forcing tire onto rim. I have done this before with other tubes and have never had an issue. I have noticed that valves leak after a lot of rides so make sure you check your PSI before you head out for a ride. The final verdict. These tubes would not be reliable if I were stranded on the side of the road and needed to change a flat. 80mm tubes are the way to go.
👤They're very light. The ride is smooth and fast, and I like it. I wrecked 2 of the 5 tubes by pinching them with tire levers, because they're so thin. Unless you're an expert at installing tubes and tires, you should use extras.
👤There is not much to say here. Tubes that hold air are nice. I picked them up for a good price and have not had any issues. I have deep dish wheels that work perfectly with the 80mm.
👤They're light, they hold air, and I haven't had a flat. It's a pleasure to have 5 of these. The Continental Grand Prix 4000 are 25 cmx 700cc.
👤Continental have been good to me and these are no different.
👤Tubes are nice. Light weight is 83 grams. There are valves that can be replaced. I will be using these for my regular inner tubes.
👤lite weight race tube. I would expect less puncture resistance.
👤Some of the tubes had holes in them that wouldn't hold air. Maybe these were seconds that we mistakenly sent, but not the quality one would expect from either Amazon or Continental.
👤The best CONTI tubes are here. Go for it and don't regret it.
When airing a tire from a flat, please follow the inflation instructions. Pre-installed with Slime Sealant, it provides puncture protection and prevents flat tires on your bike. For up to 2 years, seals tire punctures. Presta 48mm is the valve type. 700mm x 28–35mm is the correct tire size. Designed to seal punctures.
👤It is a tube and it has something inside. That's all. There is a I got a puncture on my second ride on this tube, but the seal feature didn't work for me, as I failed to seal the hole. The max hole size that is supposedly sealable is just larger than 3mm. None of my other tubes had a hole that big. Maybe the tube is designed to rip just enough to be above the size that is promised to be sealable? Who knows? It's possible that the pressure range is too high for the seal to happen. It didn't work for me. There is a The tube can't be patched because it continues leaking and the patches don't stick, which is the worst part. I've tried patches that worked in the majority of other flats, but they don't stick properly. A bit of air leaks out when I pump the tube. The tube is not usable after it has been damaged once. There is a The tube did not seal the puncture, and it is not patchable. There is a P.S. Oh yes. The tubes are a pain to pump because the slime keeps leaking out the valve and into the pump, which is a risk of clogging it.
👤These were cheap as add-on items when I bought a bunch in March. I had a chance to deflate the first one immediately during the first week of use. The autopsy showed something that was less than a 1/8" hole, but perhaps not within the "instant seal" tread zone, or at least on the border of the tire's sidewall. The Presta valve is not up-to-snuff and when you remove it, green goo can spray your clothes or carpets. The valve stem of the bike pump can be sprayed with the goo, which can cause a jam. I'm patching them and assuming they have the same generalDurability as ordinary tubes. I'd probably return them if Amazon hadn't offered them so much.
👤I bought 3 of them. I always make sure to rub the inside of the tires with my fingers to make sure there is no debri. The first one worked well. I got the second one to 10psi below the manufacturers recommended pressure and it popped like a balloon and sprayed all over the place. It is giving me false readings on two pressure gauge. I pumped the third one up to 28psi. The manufacturer recommends 100psi for my tires. I thought it was because the slime was messing with my pressure gauge, but I tried it in the other tires and they work fine. The tire is still reading 28psi. I will not be buying these tubes again.
The package includes a bike repair tool kit, a portable carry bag, and a metal RASP. Easy to collect, quick to take out, and easy to use the tool kit make it easy to put all items together. The Presta Valve is Threaded with anRemovable Core. If you have an old inner tube, please check the side of it for the correct valve size and length.
👤My bike is a light trail bike, but it gets ridden a lot. When the tires were worn through, I decided to replace them with new ones. For thousands more, that set of tubes lasted. There is a I put on a new rear tire and set up my CX indoors on a trainer, because my Kenda mild knobbies were loud on a trainer. When I removed the training tire a few weeks ago, I accidentally pinched the tube with the tire levers and poked a tiny hole. There is a I only needed one of the two packs of tubes, but I used my mountain bike in the meantime, even though they normally last me years at a time. Throw the Kenda back on after opening a tube, mount it to the rim. Set the bike to the side so that it can be ridden the next day. There is a The rear of my bike is flat. I will censor my next few words. I pulled the tire and tube off and checked my rim, rim tape, and tire for any issues. All is clear. If you want to try for a tube, grab tube #2, mount it, and head out to the trail. The tire is losing pressure 15 miles into the ride, and things are feeling a bit squishy. I was fortunate to find a trail side pump, but I didn't bring a mini or inflator. I pump it back up when I am on tubes. I took the bike out for 22 miles and put it in my car. It was un loaded the next morning and completely flat. 0/2. These are just junk tubes, I am perfectly willing to admit when I goof up and ruin a tube. Even if I had a third sitting on the shelf, I wouldn't use it at this point, as I would be worried about it failing and waiting for it to fail.
👤Why do you have to spend so much time making a product like this? A short presta valve. Thanks for wasting time. If you don't know anything about the cycling products industry, you should turn your factory into an animal rescue center.
👤I have a bike for both road and single track trail riding. It is very difficult to get tires to seal on the rim without tubes. Tubes are prone to pinch flats if not inflated with higher pressures on trails. The traction is reduced by the higher pressure. I can run lower pressures and avoid pinch flats with the help of the tubes and tubeless sealant.
