Universal moped inner tube. This is our house brand tube, it comes straight from the factory to our warehouse, so we are able to offer them at a discounted price.
The tubes are marked 17 x 2in, but will fit a range of 17inch tires from 2.0 inches wide all the way to 2.25.
These thick tubes are really nice and harder to puncture with your screw drivers or tire irons than other cheapo tubes out there.
You must use these tubes if running 2" wide tires like the IRC NR58 or 2" width stock tires, as regular tubes will bunch up inside the tire.
