The Park Tool SBS-1 is a shop quality set of sockets, hex bits and Torx® style bits for the bike mechanic. Ideal for use with Park Tool Torque Wrenches, the SBS-1's 3/8" drive bits and sockets are made from tough, chrome vanadium steel for long life.
The quality of the bits seems fine, but not exceptional. The rail is a rubbery plastic and is designed to be wall-mounted, though it holds the bits well enough in a tool box, too. Its certainly a good array of bits for bike work, and I have no idea where else youd get a 3/8" drive 1" socket or a 3" long 10mm hex bit (also no idea what those are supposed to be for, but hey, never hurts to have them). The one drawback here is that theyre made in China according to the box they came in. Nothing against China but if Id wanted Chinese tools Id have gotten my hex bits from Home Depot, not Park. Im saddened to see another American toolmaker go down that road.
