20-inch inner tube (50cm)

Item sold individually, to mount on a unicycle.

20" inner tube:

This inner tube fits on a 20 inch wheel (50cm).

Change your inner tube:

• Remove the wheel.
• Remove the tire from the frame.
• Change the inner tube.
• Put the tire back on.
• Put the wheel back on.

You'll just need 2 tire levers and pliers or a wrench depending on the model. Deflate the wheel, then loosen the nuts. Then, remove the wheel. Using the tire levers, remove the tire from one side (if you want to recover the old inner tube, be careful not to pinch it). Finish by hand. The inner tube can then be easily removed. Put on the new tube and reassemble the tire by hand, being very careful not to pinch the new tube! Replace the wheel. Remember to tighten gradually by centering the wheel (it must "turn round". Finish tightening the wheel. Be careful, you should never over-tighten a unicycle wheel to avoid damaging the bearings.
