Inner Tube Quality

[drjay9051]

Being new to mountain biking I decided to learn how to change a flat and carry proper tools. Purchased Q tube thorn resistant inner tubes but they are VERY heavy so i'm returning them.

In Dick's Sporting Goods today picked up a couple of Avenir tubes at $6.99 each.

Got home and decided to pump them up to assure they were not defective.

When i inflate they each have an area where the rubber bulges. Not a small bubble but the entire tube for an area about 5-6 long is bulged. No leaks after 10 minutes just not uniform in shape.

Is this normal? Will the tube regain proper shape when inside a tire and inflated?

If these are not good tubes what do you all recommend in a tube?

Thanks.

Entirely normal. The tube just enlarges to fit the tire.

Thanks for the help, Shiggy. Not a whole lot of reviews on tubes !!

Before I went tubeless, I personally always had very good success with the Continental MTB Light Tubes. Usually around $9 each, reasonably light at 130 grams and made for tires up to 2.5".
