Checking the Condition of Bicycle Wheel Bearings - Road

The “valve test”. A quick way to check wheel bearings is to lift the bike so that the wheel in question is off the ground. Then place the heaviest part of the wheel, which is usually the valve (or wheel reflector if you have these), at 3 o’clock. Now, release the wheel and see if the weight of the valve (or reflector) is enough to turn

Standard bicycle bearing ball sizes | BikeGremlin

Apr 13, 2017· Bicycles usually use ball bearings. Modern cartridge bearings come as a closed unit – with balls and races packed in a single unit. However, many bicycles still use older, cup and cone system, where balls can (and should) be replaced with new ones when servicing bearings. This is the case with most Shimano hubs (wheels) – they still use the cup and cone system.
