YunSCM 700x35/43C Heavy Duty Bike Tubes 35/43-622 48mm Schrader Valve 2 PCS

These heavy-duty bike tubes have worked very well as replacements for my bike tires. The sizing was accurate, and the 700x35/38/40/43C range makes them a convenient option if you need a tube that fits several common tire sizes. The tubes feel thicker and more durable than some standard tubes I've used, which gives me a little more confidence when riding on rougher roads and trails. The Schrader valves are also convenient since they work with a standard pump. Installation was straightforward, and I had no issues with the valve or fit. They hold air well and have been reliable so far. Overall, these are a good-quality, heavy-duty replacement tube at a reasonable price. Good fit, easy to install, and a solid choice for everyday riding.

Good Product, you can feel the thicker tube material and the weight of the tube. I have been using these tubes for sometime in tires using 75lbs of pressure and they have held up well with probably 100 miles on them at this point. Seems like a good product at a fair price.

good quality tube and stem... works as it should.

I am rating the tube high due to how durable they are. However, one of the tubes had a hole near the valve that I discovered a couple minutes after I installed the tube in the wheel and tested my bike (note that I didn’t over-inflated the tube). For those who are buying this product, please be sure to check the tube for any defects prior to riding your bike.

good replacement tube. will update if there is a problem after more use of a street pleasure bike.

Installed on my son's bicycle. He uses is on roads, paved trails, a few sections of grass/gravel. So far no problems after a year of usage.

Good as gold

I replaced an existing tire and decided that it should have a new tube to go with it. The tire was worn and a couple of years ago it had a flat that I patched. So I deflated the tire and removed both tire and tube. I checked the rim and found no sharp edges. I replaced with the new tube and tire using the handy plastic tools the tube company provided with its product. The tube does not have a max or minimum air pressure but the tire states 50 to 75 so I inflated it to 60. It held that pressure over night and the next day I set off for a ride. Everything was great but at about 5 or six miles it went flat and quickly. I walked it back to a WAWA and filled it but it went flat in about a quarter of a mile. I again walked it back and not having any tools I purchase a can of flat fix filled it to 60 and after checking several times decided to finish my ride of an additional 15 miles. Great the flat fix worked. I sat and had a lunch but when I came back the tire was flat. I was able to walk the bike to a bus line and get back home where I took the tire and tube off the rim. The leak is a tiny pin hole along the seam opposite of the valve stem. I have cleaned the tire and checked the rim and found nothing that would have made a puncture. It is my opinion that the tube was defective.

Gets the job done. Replaced my inner tubes after a few years of use which I should have done much earlier. I've had them for a few months now and haven't needed to pump the tyres at all. Previous ones kept passively leaking after a few punctures which I had to repump every few rides.
