Hub Bearing Adjustment
The hub bearings of both wheels should be inspected for side movement.
Adjustment is required if there is any more than slight lateral movement.
To adjust:
Remove the wheel from the bicycle.
Use a flat, open ended cone spanner to hold the adjusting cone of the hub
and simultaneously loosen the hub’s locknut on the same side.
Turn the adjusting cone as required until there is minimal side play, and before binding
of the bearings occurs.
Hold the adjusting cone in position and secure the locknut.
Test that the wheel spins freely without excessive lateral movement, or binding
on the bearings.

Hub Lubrication
At least once a year your wheel bearings need to be disassembled and re-greased.
Riding in very muddy or wet conditions will mean more frequent servicing. Due to the
complexity of the task you may prefer to have a professional bicycle mechanic perform
the disassembly. However, if you feel capable the process is listed below:
1. Take the wheel out of the frame.
2. Remove the axle nut, cone lock nut, and the bearing cone from one side of the hub axle.
3. Remove the axle, complete with the cone and lock nut, from the other side of the hub.
4. If your bicycle is fitted with dust caps, carefully remove them from both sides of the
hub to expose the ball bearings.
5. If ball bearings and ball retainers are present, carefully remove these from both sides
of the hub.
6. Remove the freewheel on rear hubs with screw on type freewheels before
disassembling the axle. (You will need to use a special tool to do this.)
7. Clean all the hub components thoroughly and check for damage, especially looking
for pits or grazes in the bearing surfaces and cones, and damaged ball bearings.
Replace if required.
8. Insert grease into each clean or new ball bearing and into the inner cups of the hub,
and refit.
9. Re-assemble the hub axle in reverse sequence to disassembling, taking care
to properly re-adjust the bearing cones.
