If you own a torque wrench but you're still using random hardware store sockets to drive it, you're probably dealing with poor fitment on bike-specific fasteners. Park Tool's SBS-1.2 Socket and Bit Set solves that problem with 18 pieces selected specifically for bicycle service work. Every socket and bit in the set uses a 3/8" drive interface, which means they drop straight into Park Tool's TW-5.2 and TW-6.2 torque wrenches, the SWR-8 ratchet handle, or the SWB-15 breaker bar without adapters.

The hex bit selection covers 3, 4, 5, 6, 8, and 10mm — that's stem bolts, seatpost clamps, brake caliper mounting bolts, crankarm pinch bolts, and most other fasteners you'll encounter during a full bike build or teardown. The set also includes long-reach 5, 6, and 10mm hex bits for recessed or hard-to-access fasteners where a standard-length bit won't reach. On the Torx side, you get long-reach T25, T30, and T40 bits, which handle disc brake rotor bolts, chainring bolts, and brake lever clamp hardware. The socket selection rounds things out with 8, 9, 10, 13, 14, 15mm, and 1" sizes. That 1" socket is the one that fits Park Tool's own freewheel removers, cassette lockring tools, and bottom bracket tools like the FR-1.3, FR-5.2, and BBT-22 — so you can drive those tools with a torque wrench instead of an adjustable wrench.

Everything in the set is chrome vanadium steel, which holds up to repeated use without rounding out fastener heads. One thing to note: these bits are designed for hand tools only. Park Tool specifies that the SBS-1.2 is not rated for impact drivers or power tools, so keep this set paired with your manual torque wrenches and ratchets.... Read More
