2 Pack 700 x18-32mm Tube 45mm/65mm/85mm Presta Valve Tube

These seem like a great value, but the connection of the valve to the tube needs some work. Of the three that I installed two leaked around the valve stem connection.

I mounted the tubes on my wheels without issues of any kind. They appear to be of excellent quality and are as advertised. I will test their ride quality and durability in coming days. So far so good 👍

I love tpu tubes, one of these installed without flatting and rides great, makes it nearly impossible to go back to butyl or tubeless. The other is just going to be flat. Makes me reconsider using them since I spend all my free time dealing with the tubes.

I bought these because they are less expensive than Tubolitos. I had read the reviews which said that they didn't hold air for very long, but my plan was to only use them for an emergency when my tubeless set up didn't seal. So I figured I'd get by...On my ride this morning, I had an emergency and needed to use a tube. I got the tube installed and inflated no problem and it was holding air, so I was happy. But, it only held air for about an hour. When I got home from the ride, I pulled the tube out and figured it had a hole that maybe I could patch, but when I checked it thoroughly, I found 4 holes. I'm not going to patch 4 holes and try to use the tube. It will fail. The tube is trash and I won't be buying this brand again. :(

You can get cheaper tubes. I tried some and they did not last. Spend the little extra and get quality.

I really liked the weight Factor but I don't think these tubes are very reliable. One leaked at the base of the valve stem after one day and the other blew out in an hour and a half. You could buy a light butyl to and get the reliability that goes with it. Yeah they're like just like a trash bag. I am no longer keen on having trash bag thickness tubes in my tires to save and imaginably a small amount of weight. Buy em try them see what happens for you

Inner tubes should be simple, pop them in, even if it's carefully, pump them up and off to the races. Not these bad boys, they install simple enough, but then it's a fight to get them to hold air, which is the only thing they should do!After I installed and inflated, I put the bike away for a ride later in the day, came back and they were flat. Re inflated and really tightened the valve end as tight as possible and one seemed ok, the other would leak from the stem base. Bunch of hassle and messing around later, I never even got to use these, back on Butyl.

I’m sure the tubes work fine, but they came with different stems. I know hey weigh different, but I don’t really care about that, I care more about the fact that they’ll look different on my bike.
