Good to know
- Heavy duty tubes use a thicker wall for pinch-flat resistance at low pressure, at the cost of a little weight.
- Match the tube to the tire, not the bike: a 19" front and a 19" rear take different tubes.
- Fit a fresh rim strip over the spoke nipples when you change a tube, and add rim locks if you run low pressure off-road.
