## Description

Impressive joint and valve strength; for Valve Stem Types see above Two to three times thicker than standard tubes IRC heavy-duty tubes are incredibly durable abrasion-resistant and feature great impact-absorption

Review: 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.

## Questions & Answers

**Q: Listing says "standard" and "heavy duty". Which is it?????**
A: I wondered the same, it seems to be thicker than a standard tube by a fair amount. It is a good quality tube, especially for the price.

**Q: Will this fit a mh90-21 Avon cobra chrome tire ?**
A: Yes it will it will fit any 21inch. I have the Dunlop harley tire and it fits fine.

**Q: Where do you put the two nuts?**
A: One nut goes at the base of the valve stem inside the wheel, the other nut should NEVER be used against the rim on the outside. It should be up against the valve stem cap.

**Q: Will this tube work for 90 / 90 - 21 ?**
A: Yes, 2.75  / 3.00 / 21 is  the same as 90/90-21
