The Bones Bearing Tool is a bearing press and puller in one handy pocket sized tool. It makes installing and removing bearings quick and painless and can be used with any 8mm bearings, including those with spacers! Very useful for derby skaters to keep in their skate bag for when they need to change wheels on the fly to get the right amount of grip. Compact, lightweight and made of the strongest aluminium, this is the best and the ONLY bearing tool you'll ever need. Stop destroying your bearings and start destroying at the skatepark!
