Keep a container next to you and put your "loose ball bearings" straight into it as you’re removing them from your hubs. They’re easy to lose and seem to like nothing better than rolling into hard-to-reach places, particularly under the fridge.

Get a magnetised screwdriver blade to make life easier for yourself when removing loose ball bearings from a hub – the balls bearings will stick to the magnetic tip without the need for more sticky grease. Either buy one or magnetise your own screwdriver by dragging its blade over a fridge magnet several times in the same direction.

A cup and cone hub makes use of loose ball bearings and allows you to easily adjust bearing tension, unlike most sealed bearing hubs that don't allow for any adjustment. They consist of the "cup" that acts as the bearing's outer race, which is pressed into the hub shell and not replaceable, and the "cone" that serves as the inner race and threads onto the axle. The hub bearings, which are usually 1/4" in rear hubs and 3/16" in front hubs, spin between the cup and cone. timken Bearing tension is adjusted be threading the cone down on the axle, and then locking its position in place with the locknut (a spacer between the cone and locknut allows you to tighten the two against each other easily). Front cup and cone hubs are usually symmetrical, although the hub will be offset slightly to compensate for its rotor disc rotor mounting. Rear hubs use a freehub (the clutch mechanism that allows you to coast) and the driveside cone and locknut can be found set within, sometimes hidden from view.

Always use the smallest cone wrenches the fit. Most front hubs will accept either 13, 15 or 17mm sizes, while rear hubs often take 15, 17 and 19mm size wrenches. A crescent wrench can be used on the outer locknut.
