Blackburn Heavy Duty 20" Bicycle Inner Tube, Schrader Valve

The tubes are nice and thick. We live where punctures happen often and have faith that these tubes will hold up!

Order was here as expected. The tube fit and it was good quality. Easy to install. The tube sealed properly. Still working on bike today.

comes just as described. It fit perfectly on my bike.

Heavy duty and good quality

It served its purpose

There is not a lot to say about this inner tube other than it fits and works. It came packaged well and seems of good quality. It is hard to take a picture of an inner tube once it is installed so I took a couple pictures of the box and the inner tube after first taking it out of the box. So far it is holding up great and most importantly holding air. I recommend this item.

These Blackburn heavy duty inner tubes do the trick. The rubber is thicker than most tubes and 2 tire levers are included to help install them. We got new bikes for the kids at Christmas and noticed the tires kept going flat, replaced with these tubes and have not had issues since! It took maybe 30 minutes to install them and get the bike back together. Recommend!

This inner tube is perfect. It really is heavy duty. Last year at the beginning of covid I bought my son a new bike and every week he was somehow ripping through his back tire's inner tube. We were so happy to try this one and it's worked perfectly the whole time.

The picture shows that this item comes with bike levers. The item I received was slightly different, no levers. Sold separately $. I managed to remove the tube (and old tire) and replace both w help from paint can opening tool.

Installation was simple. Inflation took a bit longer than expected and didn't hold well.
