BWSHLF 27.5" /29" Mountain Bike Inner Tubes (2 Pack), Durable Butyl Rubber MTB Bicycle Replacement Fit 2.1-2.4/1.75-2.3, Presta Valve 48mm

I love the fact that with these tubes u instantly notice just how durable they must be and are because they are noticable and thick like if you're the type that goes into a harsher than normal area off the beaten path as I routinely do or at least I can say I did before for some reason my neighbor decided to keep my bike for what I'm unknown reasons and still has it you would see that you shouldn't have any fears when it comes to this bike Early Access to say if those internships suffering from punctures because they are noticeably thick I mean literally when you put them in you notice instantly once you you know put your tires back on or not you feel the fact that there is a thickness it feels like there's already airing the room and your tires even though there isn't but I have never had a puncture with those with those tubes all I can say is that I did have one incident happened where once you will essentially I guess it must have been 02 or something but upon inflation actually have a complete down stem you know separation from the actual tube they replaced it you know so I can I have to say that they're more she's great and the products are awesome

Perfect fit, easy to install. Seemed like a very durable high quality tube. Been on a few rides and no change in air pressure

Product arrived on time it was the right size install was easy no leaks.

Holds air

These seemed to be the best value I could find for my replacement innertube and they did no disappoint. I have only used one of the 2-pack but there were no issues with it. For what it's worth, I put a little smear of silicone grease around the the area where the valve stems attaches to the tube. I did this because the tube I was replacing had rotted in that area, presumably from interaction with the rim. I don't know if this will give longer life to the tube but I figured it's worth a try.

Both tubes leaked at the seam right out of the box. Didn't use either tube a single time. Don't waste your money on these useless cheap tubes.

Perfect fit. Install and go

Even though the tube fit my mountain bike just fine. I had to get a special adapter to put air in the tube. Now I have two tires with two different valve stems.

Me gusto precio buena calidad
