🚲 TAC 9 Tube for Bicycles - 700c x 18-23, Presta Valve, 32, 48, 60 or 80mm Length - Choose Valve Size and Money-Saving Option in 1 Pack or 2 Pack Review

I have these inner tubes in my 700x25 tires and they work like any other inner tube. I always buy smooth steerer tubes and it saves me a few bucks compared to other brands. All whistles, no matter what brand you buy, come from China or Taiwan.

Hey what can I say? These tubes saved the day. My French 10 speed went flat with a cracked presta valve. I ordered them and they arrived as advertised, went in with no problems and now assist me in riding. I'm always looking for good deals on Revain.com.

First I got a broken tube, then they sent me another one to replace the broken tube. after installing the pipe. I did a group hike. After driving less than 3 miles I blew out a tire. So I decided to put my old camera in and rode over 50 miles that day with no problems.

I am a trained bicycle mechanic and after installing these hoses I had two sudden bursts in a row. Which is especially awful when I'm driving in fixed gear, which means changing a tire is real agony, with all the tightening that has to be done on a wheelset to put it back on. So I was very unlucky and gave up and just put on an old wheelset because I ran out of inner tubes.

There were problems connecting a floor pump to these valves. The wheels are 50mm and I have 60mm valve stems which work great with other threaded stem tubes but it was almost impossible. I had to use a Schrader adapter to fill them. Once there was some pressure in the hose you could hook up to it but it still slipped off easily.

The hoses are gradually losing pressure through the tip. I rode the bike about 20 miles and the pressure went from 110psi to about 20. The pressure was slowly released every time I filled it up for 3 or 4 days. I took the tube out and submerged it in water and there was a very small leak in the metal area of the tip, not at the clamp screw but just below where it looks like a metal cylinder is welded to another metal cylinder. There's obviously no way to fix this, so I hung up. Exactly the same

judging by the reviews these whistles are scattered around the world, I don't know why? The product description states that these tubes can withstand high tire pressures and for me they have held up very well. I run Vredestein race tires on a Cannondale road bike at very high pressure, over 160psi. These tubes seem to handle it with no problems. I ride busbars so maybe this will help? I'm not sure, but these bulbs appear to be of much better quality than the Giant bulbs they replaced, giving me

Terrible product. The quality is cheap, made in Taiwan. To prevent tire blowout, follow the instructions VERY CAREFULLY AND CAREFULLY. I was able to ride the bike once then when I checked the bike again the interior burned out. Place the 2nd inner tube GENTLE AND CAREFUL, making sure the tube is positioned correctly to avoid pinching - there were areas in the 2nd inner tube that swelled disproportionately to the others. I took the tire off and made sure the rubber had weak spots/zones that were

Pros: Reasonable price. Page 18-23 is not always easy to find. Useful instruction card. US company owned by a retired US Air Force. Disadvantages: So far 2 out of 4 tubes have failed while stationary. Not all sizes come with an optional threaded Schrader valve. I bought 4 of these tubes and installed 2 in my fix that has sat for a couple of years. Although I have a lot of experience, I followed the manufacturer's recommendations for installation and carefully checked the tire bead several times
