Bicycle inner tube 28x1.75 is an inner tube for 28-inch wheels fitted to city, touring and road bicycles. It goes under a tire of the corresponding width.
- Replacement is needed after a through puncture, a cut, a torn-off valve or when the rubber loses its elasticity.
- Check the size on the tire sidewall: 28" and 26" tubes are not interchangeable.
- Choose the valve type to match the hole in the rim.
Inflate to the pressure indicated on the tire.
