Great IRC Quality
Needed a replacement tube that could handle the gnarly rocks and roots I ride over. Tube is heavy duty and very thick. Stem feels like good quality and has good hardware for holding the stem in place. Installation was definitely more difficult than a thinner tube, but no where NEAR as hard as I had imagined. Was just a little careful and did my first solo tube change with one of these and no pinch flats.After installing I made sure to inflate the tube juuuust a bit so it expanded into the tire and that made all the difference. I also took my time in reinstalling the tire and was super careful with my spoons.Definitely recommend.

Standard tube NOT heavy duty
Seller sent me the standard tube which has a blue ring, not red. They put a heavy duty label on the box hoping I wouldn’t notice. Don’t fall for this scam.
