I’m hoping this will work on a front and stay inflated.

Rubber has got to be 3x as thick as the 2 from the store.

Much thicker rubber I don't think it matters how hard you ride it won't bust.

Best tubes out there

My sons and I do alot of riding on land filled with catctus, yucca, sage and rocks. We would have at least one flat between us every time we rode. Installed these tubes in all our bikes and haven't had a flat since.
The price is great and Bike Bandit service is excellent!!
Keep it up guys!!

Really, No, I mean Really Heavy Duty

these tubes are really thick, I was amazed at how big a box they were in!, I hope they keep air in them as well as they look like they should!, these tubes are the thickest tubes I have ever bought, and I go thru a lot of tubes in a year, I always try to have a few "spare" tubes in the trailer for customers, these should impress everyone that needs one.
