Avenir Regular Smooth PRESTA Valve Tube

My bike commutes a lot through the bad streets of L.A. This tube is a good replacement with a reasonable price compared to bike shops

After fighting to get these tubes in my 28C tires I saw on one that the tube is marked 32-38C. I got one in and ended up putting a 19-25C tube in the other tire after putting 2 holes in this tube trying to get it in. I would not use if you are in the 28-32C tire range. Otherwise its an okay basic tube.

I have a bike from 1979 with a 27 x 1-1/4 inch tire. It fit without a problem. I bought 3.

It's rediculously difficult to pump air into this tube. Because of the smooth valve, there's no backstop to hold it in place when trying to put on the pump connector. The valve just gets pushed into the rim opening.

received my tubes but when I tried to use the wrong size where in all ten boxes have return the items waiting for creit and looking for a better place to buy tubes

Received tubes and looked fine till installation. After putting in only 40psi, the inside valve blew out and let all the air out. Poorly constructed.

This piece of trash has ruined my last 3 months of biking AND my last 40 minutes..... others were lucky to have the seam burst on their, mine (both front and back tires have it) will pump up to about 120 psi, then slowly (over an our or so) leak down to about 80 psi - but no lower. So you think everything is okay, then you go out and, surprise, you have not a full-on flat but a too-squishy tire. And here is the kicker- the stems (both of them) are either designed or broken to NOT allow the air out, so I have spent about an hour trying to take the tube out from a nearly, but not quite, inflated tire...... what a piece of garbage.... and both tubes are deficient in the same way, so it appears someone actually thought they were good design features?!?!?!? Have they ever actually RIDDEN a bicycle. I hate, Hate, HATE this product.

Installed one of these on my Surly Karate Monkey and it was total garbage. The presta valve broke and immediately began leaking air out.
