Changing a Puncture

1. Remove wheel (see reverse of wheel installation below)

2. Let air out of tyre (unless already flat).

3. Using a hex key undo the bolts holding the hub together. (Take care not to loose nuts and bolts). (or untwist hub if mbs twistars)

4. Split the hub apart and pull the inner tube out.

5. Check the inside of the tyre for spikes or debris.

6. Repair the puncture as advised in cycle puncture kit.

7. Put the repaired (or new) inner tube back into tyre.

8. Pump inner tube up slightly so it fills the tyre and does not have any creases.

9. Place hubs back together. (There is a hole for the valve to go through).

10. Tighten the hex bolts back up equally ensuring the tyre and tube fit snugly and correctly onto the hub.

11. Replace wheel back onto axle and tighten as indicated in wheel installation.

12. Inflate tyre to pressure of other tyres.

Wheel Installation:

1. Remove nut from axle.

2. Slide wheel onto axle (valve stem pointing inwards).

3. Tighten nut onto axle until it is tight.

4. Loosen nut ½ turn so that the wheel spins freely.

5. Make sure the treads are fully though the nut and nylon insert.

6. Repeat for other wheels.
