Ultraverse Bike Inner Tube for 26, 27.5 X 1.75/1.95/2.10/2.125 inch Bicycle tire Sizes with Presta Valve - Rubber Tubes for Mountain and Trail, Cruisers, MTB, and All Terrain Bikes – Set of 2

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.

On the road again!

I liked that it came with tire tools. Only thing I didn’t think about was you can’t put SLIME in this tube since the valve core isn’t removable. Well if thorns become a problem I can install a tire liner.

Only had the tubes for a few days, but install went fine. I like that they give you some pry tools to get the tire on and off. Great product and the company really stands behind their stuff! Thanks!

The installation was super easy with the included tools. The quality of the inner tube was noticeable improvement from the original tube. Everything was great.

I have 20 years experience as a bike mechanic. I installed two tubes correctly and they went flat in a half a mile. In both cases, the stem leaked at the junction of the tube. Obviously faulty construction… Beware!

Same quality product ive gotten from local bike shop for a more affordable price. Riding on city streets means lots of flats. Going to order more to keep them on hand. Comes with a lever if you don't already have a set.

It's a bicycle inner tube. I bought it for use on my indoor trainer and it works exactly as expected
