MEETLOCKS Bike Tube 700x38-45C Recycle Butyl Solid Brass Stem Valve Schrader

It fits my rim and tire with no problem. The issue is the valve stem is too short. I have about 2mm clearance from the rim to the bottom of the valve cap when fully screwed on. Makes it difficult to get the air pump on sometimes. The tube dimensions are identical to what is on the tire and what is listed in the manual for the rim, so maybe a quality control issue or they are saving money by using a shorter stem. It does hold air well with no abnormal leaking after two months of hard use.

First tube's valve was cracked so it leaked as so as I added more that a little air with my hand pump. Used a hand pump on the second tube but it burst as soon as I used the electric pump (which I use weekly and have never had a tube pop). Two tubes wasted in an hour...won't be buying these again.

Does not fit my 700x38c tire. I assumed that it fit anywhere from 38-45, so bought it. I guess it only fits 45c, so I cannot use it to fix my tire. Disappointed since I waited to have other things to order since this was an "add on". I will be letting Amazon know I need to return it....

Bought the two pack for my hybrid bike. The first one sprung a leak after the first (10 min) ride. It made a loud hissing sound and deflated about 3 hours after the ride (I rode to work). I got home and put the second one on inflated to 75 psi, and it popped as I was wheeling it to another room. I didn't even know inner tubes could pop like a balloon! I examined both tubes, and they both failed in the same place, right next to the valve. I looked at the rim and there were no sharp bits, and the rim tape was intact. Don't bother with this product, spend the extra few bucks and get a name brand tube.

Bought to replace a Schwinn factory tube that came with the bike, which was punctured by a surprisingly small piece of wire. The Meetlocks tube was easy to install and fit nicely. Good thing there are two tubes in the package, because a couple of weeks later I was replacing the other factory tube, which had also been punctured by a surprisingly small piece of wire.These tubes are noticeably thicker than the factory tubes they replaced. Four star ranking only because I haven't had them that long. Hopefully I can come back after several months time and upgrade this to 5 stars.

Bought this 4-pack to replace the ever-leaking 10-year-old tubes on both my wife's and my bikes. We only ride recreationally and high end tubes seemed like overkill.Installed them myself. Didn't take too long. Hardest part was figuring out the quick release on the brakes. Didn't keep track but seemed to take maybe 60 min to replace all four. They have now been on the bikes about a month and zero issues. Nothing to fault here.Unless something fails in the future (I'll post an update if that happens) I have nothing but good things to say. I would definitely buy them again.

Bought these in July 2015 to replace a presta style tube purchased locally and have a spare. The first replacement has lasted 1,000 miles. I had to use the second today as the other OEM tube developed a leak by the valve. So far so good. One came with a green cap, which split, the second didn't have a cap. Not an issue as I kept the caps from the OEM tubes. They lasted up to 4,000 miles. Let's see how long these will last.

Picked these for the price, and after a couple hundred miles (mostly asphalt and concrete, but some gravel and rough boardwalk) have not been disappointed. I got 700x35 schrader-valve tubes, which fit my hybrid Trek bike well and were easy to put on.The caps are neon green, which is handy if you drop a valve cap in the dark but may not fit with your individual aesthetic.

These are the bees knees, two individually wrapped inner tubes in a single outer box the perfect size for popping in a back back or pannier, much better than carrying around all those patch and glue kits.Just the job for a quick change at the road/trail side and you're back on your way in minutes so you can fix the puncture at your leisure and in the comfort of a well lit, dry environment later.These handy tubes come with either schrader or presta valves to suit your cycling needs.

Okay so far but it seemed a little loose for my rim which is a "29er" (700c).Also the dust cap is bright green which I guess makes sense if you need to find it in a hurry in the dark?? I like my bike stealthy.

Excellent value.

Used it, hasn't broken meets all requirements of inner tube.

Does the job!
