Bike Inner Tube, 26/27.5in x 1.75-2.125, Presta Valve | Rubber tube, fits mountain, trail & all-terrain bikes, 2 pack

I normally run a tubeless set up, but my tires are very worn right now and I plan to replace them when I have the extra cash. The tire sealant hasn't been replaced in 2 years and I couldn't justify spending money on sealer just to turn around and buy more in a month or so when I get tires. I already had to put a tube in the front and recently the rear was needing to be pumped up daily, so I looked for the least expensive tubes I could find to keep my bike on the road in the meantime. These tubes were the best deal I ran across, and the tire levers were a great bonus. But wait.....there's more! The little valve stem tool was also a nice touch. I have no use for that on a presta valve, but they'll be handy to use for shrader valves for sure. I split the levers up and paired them with 1 each from another pair I had so I'd have a valve tool in each of my 2 bike kits. The tube itself is pumped up to 35psi and so far I've ridden a couple miles on it and all is well. Before installation I also pumped it up a bit and looked it over very closely since there were a number of unfavorable reviews. It appeared to be of good quality and gave me no reason to believe it won't last for a reasonable amount of time. I think at least a portion of the less than stellar reviews may be due to other factors having nothing to do with the tubes quality. I do know that rims are built to use either a presta, or a Schrader valve, and to my knowledge there aren't any that are specifically made to accept both. If a Schrader is crammed into a smaller hole meant for a smaller diameter presta valve, well, I think the outcome is pretty obvious. A presta left to slop around in a bigger Schrader sized hole will likely cause undo strain around the valve and cause problems as well. I've seen many new tubes damaged due to pinch flats caused by the tube being pinched between the tires bead and the rim, then inflated. Some rims have burrs and imperfections that go unnoticed and can puncture a tube. I only mention these things because from what I see, these tubes are of pretty decent quality. I suppose if my opinion changes, I'll promptly change my review, but for now I think 5 stars is a fair assessment given that even the unfavorable reviews mention great customer service and an effort to make things right on the manufacturers part, that's gotta count for something. I should also mention that I pull a heavy trailer and am pretty hard on my bike as it's my daily means of transportation. So far, so good.

Works as expected. Replacing Kendra inner tube that developed a slow leak which I could not find the source.

Well built tube, valve is a little long but fits as expected

Works good, no leaks out of the box, I’m running it at a medium/high pressure. Now I carry a second one with me in reserve, in case something happens on the road. Good stuff.

They seem like a very basic inner tube, and that's okay. They are not ultra light for racing, nor heavy duty for touring, nor with any added protection from punctures. I just installed them and the fit is good. If you're just riding around and you need an inner tube, these are probably for you.

Works great non leaky valves like other brands

Tubes worked great

I ordered this inner tube last Dec 18 2024. It was on my garage shelves since this last week of August 2025 to finally use it and install on my new tire ,disposed the old inner tube as well (after 3-4 years). To my surprise after it was installed by my friend (bike group mechanic) that late afternoon and took it home ,supposed to ride it the next morning .It was flat ! I thought he has forgotten to tighten the valve, so i pumped air again…it doesn’t hold air at all ! So i removed it …pump air and there i saw two small puncture 6-8” apart .Right on the very middle ( inside diameter) of the inner tube ,must have been pinched…Since it came with two inner tube still wrapped with plastic packaging and rubber band ,i installed myself the second one ,…this time it hold air for couple days …and there it was flat tire again !!! Even without riding on it !!! I checked everything inside and outside.. no sharped or thorn object…This INNER TUBE tire is totally garbage!!! Thought of saving money ?… NOT ON THIS BRAND !!!
