Bits and Sockets Set -1782

Most home bike shops accumulate sockets and bits over years, ending up with redundant sizes in some places and gaps in others. The 1782 set is the one-purchase answer to that problem: a curated mix of 1/4-drive and 3/8-drive sockets, plus hex and Torx bits in the sizes a bike shop actually uses, plus the drive-square adapters that let everything run off any ratchet. All in an SOS foam tray.

What's in the set

Smaller sockets and bits are 1/4-drive; the larger sockets are 3/8-drive. This split matches the torque ranges:

• 1/4-drive section: sockets, hex bits, and Torx bits for the low-torque fasteners on a modern bike (stem bolts, derailleur bolts, brake-caliper mount bolts, rotor bolts).
• 3/8-drive section: larger sockets for the higher-torque fasteners (pedal-axle nuts, crank-arm bolts, lockring work).

Two drive-square adapters are included: one that mounts 1/4-drive sockets onto a 3/8-drive ratchet, and one that mounts 3/8-drive sockets onto a 1/4-drive ratchet (within reason, for lower-torque work). The adapters mean the set works with whichever ratchet handle you already own.

Every piece in the set works on either a ratchet handle or a torque wrench, which means you can rough-fit a fastener with a ratchet and final-torque with a calibrated wrench using the same bit or socket.

What's actually in the tray

The set is arranged in the laser-cut SOS foam tray, which gives every tool its place. When something is missing, the empty cutout tells you immediately. The tray sits in a workbench drawer or stacks with the rest of the Unior SOS-tray ecosystem.

When this is the right purchase

• First serious bike-tool purchase. Covers most fasteners on a modern bike without a multi-set buy.
• Consolidating a chaotic tool drawer. One tray replaces three or four piecemeal sets.
• Travel mechanic kit. All the bit/socket work in one organized tray.

For shops that already own complete 1/4 and 3/8 sets, the redundancy may not justify the purchase. For a home shop starting from scratch, the 1782 is the closest thing to a one-decision answer.

Pairing with the torque wrench

Pair the 1782 set with the 2-24 Nm Slipper Torque Wrench for low-torque work (rotor bolts, derailleur bolts, stem bolts) and the 5-110 Nm Slipper Torque Wrench for higher-torque work (pedal axles, crank-arm bolts, lockrings). The drive adapters mean every bit in the tray can move between the torque wrench and a normal ratchet handle.

Made in Slovenia, since 1919

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. Curating a mixed-drive set is harder than building two separate single-drive sets; we did it because the bike-shop reality is that the most-used sockets and bits sit on both sides of the 1/4 to 3/8 boundary. A purpose-built mixed tray reflects how the work actually flows, not how the catalog is organized.

Pro tip from our mechanics

The foam tray is what makes this set a long-term solution rather than a six-month upgrade to chaos. For the broader bit and socket framework that explains which drive size belongs where: Sockets and bits for bike work →.
