Wheels
Worn out your wheels yet? This is normal once you get up to speeds especially with the rear wheel.

The rubber on this wheel takes the hit when the brakes are jammed on or from skids.

Replacement wheels are easy to find from most sports shops. keep and eye out for the size of the wheel and bearings to make sure they fit.

Mast
Broken your mast? Don't laugh it happens.

I have repaired a broken mast that sheared off at the top of the steering bearing using some steel water pipe.

Go to you local steel shop and select a diameter pipe to insert tight into the deck bearing and upwards into the handle.

Take this home and cut to size. Hammer into place and secure with the mast clamps.

The pipe should be a tight fit into both sections.

This repair has the downside of being unable to slide down the mast during fold up. But who needs to pack it away anyway.

The additional weight is hardly noticeable.

Bearings
Wheel bearings are easy to change and with the right ones you can have a smoother and faster ride.

Bearings are rated on a smoothness measurement called ABEC. The smoother the bearing the better it will work.

The best bearings are ABEC 7 the worst are ABEC 1.

You can but the bearings from skateboard shops, these should include the spacers that keep the bearings apart.

Check the size against the ones you already have.

Use an Allen key to remove the old bearings or take them into a skateboard shop to fit.
