Alta Bicycle Inner Tube Duro 29 x 2.25/2.35/2.40"/2.50" (48mm) Thorn Resistant American/Valve

Awesome innertubes I used a pair in my 29" x 2.5" Maxxis Hookworms. Very thick rubber , not sure of the mil specs but I got psi in them and I'm 6'3" 385 lbs and I'm rolling!!! I get on my bike and the tires don't buldge out, this is gonna help me get down to my goal of 250 lbs. Great tubes I'll probably buy 4 more pairs. Peace! BigJoe53!!

Great tube, as I age I tend to make more mistakes in timing when it comes to my curb hopping and stair jumping and other things that are hard on tires, tubes and rims if you don't do it just right. I began losing rear tubes more often then I'd like. Put one of these bad boys in there, no problem so far. I'm 6'1 190-200Lbs, ride a 29" Jamis. I maxed out the pressure of my tire and the tube had no issue with it, the tires didn't, but the tubes were fine at 60psi, I lowered it to about 48psi and it's just right. Mild even tire wear, mild shock absorbency, no bottoming out to the rim under harder landings. These tubes are great.

Extra long stem just like I wanted. Super heavy duty to fend off puncture vine.

There was an issue but it was addressed and corrected in a timely manner.

Product as described. Good pricing fast shipping Thank you.

the tubes are super thick and durable
