The Bont Inline Bearing Press is a wonderful tool to own for any skater who uses aluminum-hubbed wheels or frequently changes their bearings. The press handles bearing installation on one end and accepts wheel sizes up to 125mm - including scooter and roller skate wheels. The opposite end has a bearing hook that makes it quick and painless to pull bearings out of wheels, as well. The Bont Inline Bearing Press works on 608 and 688 bearings and can be mounted to a tabletop for security and convenience.
