Bell 20″ Standard Schrader Valve Bicycle Tube, 1.75-2.25″

I have used a lot of Bell tubes over many years. These 20″ will be used on a recumbent tadpole model. I expect them to perform every bit as well as the many 26″ Bell tubes of the past and present. I use the 26″ in my 26, 27.5, and 29er tires. Yes, a 29er. Never a popper in any of these, and always even inflation around the tube (I check before installation). And they have always taken any inflation pressure, low or very high.
