Add to Cart:

100/90/19 Extreme Duty Tube.

These tubes are 4mm thick, they weigh in at 2.83 lbs. If you want to add weight to your wheel or you ride in harsh terrain and want to prevent pinch flats, this is a good option. Slightly less weight & thickness than the Bridgestone but less than 1/2 the cost.
