Reinforced 10 × 2.5 inner tube with 90° valve for Dualtron Forever

Reinforced ULIP inner tube with a bent valve

The ULIP 10 × 2.5 inner tube features a reinforced design and a metal valve with a 90-degree bend. It is intended for compatible ten-inch wheel assemblies requiring an inner tube.

Features and fitment

• Model: Dualtron Forever.
• Reinforced ULIP 10 × 2.5 inner tube; 90° bent valve.

Approximate dimensions

• Outer diameter of the inner tube: 235 mm.
• Inner diameter of the inner tube: 148 mm.
• Width of the inner tube: 43 mm.
• Bent valve: length 35 mm, angle 90°.

In addition to the tire size, check the valve direction and access near the motor. The valve should protrude from the rim hole without tension, leaving enough room to attach a pump.

Replacement without pinching the tube

• Before replacement, identify the cause of the puncture in the tire or rim. A foreign object, sharp edge, or damaged rim tape can immediately damage the new inner tube as well.
• Inflate the tube slightly, align the valve with the hole, and distribute it evenly inside the tire. When installing the bead, be careful not to pinch it with mounting tools.
• Inflate to the pressure allowed for the wheel assembly. Check the valve position and sealing; do not use valve caps to stop leaks.
