What size wheels and bearings do i need

[bertscova]

My son has a set of bladerunner inline skates they have 76mm 78a wheels on them i know that the 76mm is the size of the wheel but don't know what the other # is or what bearing i need to replace the wheels and bearings can you help thanks

The second # refers to the hardness of the wheels. If skating outdoors, 78A is considered fairly soft.

The higher the #, the harder the wheel. I would recommend 82A if skating outdoors or higher/harder.

Thank you.
