My hybrid bike uses the same tubes with these diameter and width. I purchased 2 of them. As soon as I received them, I opened one of them and I intalled it. It fits the wheel as advertised, and the quality was outstanding. The tube was so thick and strong that I think no thorns can punch through, but the valve stem was too short that it could not even go through the rim. I measured the length of the valve stem, it was 23 mm; and my old tube has a 48 mm valve stem. Most hybrid bike and road bike use deep V types of rim, not sure why the valve stem is that short. I returned these tubes with free shipping, and the refund was quick. Very impressive service from this seller and Amazon. One suggestion would be to add more details in this listing.

Note to tube manufacturers: If you sell a tube specially designed not to leak, charge a few pennies more and use a metal valve stem. The tube may be fine, but I'll never know because the valve stem is cheap. After two rides, the stem developed a leak next to the wheel hole, even though it was almost straight. I've never seen a valve stem leak at the wheel that was as straight as this one, and I've seen a lot of tubes last years with much more angle on the valve stems.

This tube is very high quality, but do not use as a back up while riding. The hand pump I used was not enough to fill the thick tube so I had to walk the bike home and use my compressor to fill it. I ride at night and drive over all kinds of glass and nasty things that are hard to see and it works fine.

I coupled these tubes with slime in my bike and haven't had a flat yet (I live in Arizona, the land of the cacti.) Very pleased with the tube performance and intend to continue with this brand.

I live in a town where there are lots of thorns and thistles on the street. I bought a new bicycle, and the first time I took it for a ten mile ride I got two flat tires. This inner tube works great. Haven't had any flat tires since I installed it.
