Park Tool SBS-1.3 Socket Bit Set

The Park Tool SBS-1.3 is an 18-piece socket and bit set covering the fastener sizes most commonly encountered in bicycle repair. The 3/8″ drive collection includes hex bits in 3, 4, 5, 6, and 8mm, long-reach hex bits in 5, 6, and 10mm, and long-reach Torx-compatible bits in T25, T30, and T40 for recessed and deep-access applications.

Six metric sockets in 8, 9, 10, 13, 14, and 15mm cover axle nuts, bolt heads, and standard hardware across most bicycle platforms. A dedicated 1″ socket drives Park Tool freewheel, cassette lockring, and bottom bracket tools including the FR-1.3, FR-5.2, and BBT-22. These pieces are hand-tool only and not rated for impact drivers or power tools.
