CST 14 × 2.125 inner tube with angled valve

CST inner tube with a bent valve for a 14-inch wheel

The CST 14 × 2.125 inner tube keeps air inside the appropriate 14-inch tire. A bent metal valve makes it easier to attach a pump where a straight valve would not be accessible enough.

Features and fitment

• CST 14 × 2.125; bent valve.

Approximate dimensions

• Outer diameter of inner tube: 333 mm.
• Inner diameter of inner tube: 265 mm.
• Inner tube width: 38 mm.
• Length of the bent part of the valve: 25 mm.

Check the valve curvature direction and the clearance between the valve, hub, and rim. Do not forcefully twist the valve while inflating; the pump head must be accessible even after the wheel is mounted.

Replacing without pinching the inner tube

• Before replacing, find the cause of the puncture in the tire or on the rim. Foreign objects, sharp edges, or damaged rim tape can damage the new inner tube immediately.
• Inflate the inner tube slightly, align the valve with the opening, and distribute it evenly within the tire. When installing the bead, do not pinch it with mounting tools.
• Inflate to the pressure allowed for the wheel assembly. Check the valve position and sealing; do not use the valve cap to stop leaks.
