Protect your investment in your bearings and your trucks. Bearing presses are nice but large and not suitable for the skater on the go. Removing precision bearings using truck axles can strip the axle thread, damage the bearing outright, and/or cause the bearing to not sit flush on the wheel seat within the wheel well. So small and lightweight it can fit on a key chain. But don't let the small frame fool you, this all metal tool is built to last.
