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. Specs Drive sizes: 1/4 inch and 3/8 inch Includes 1/4-to-3/8 and 3/8-to-1/4 drive adapters Bit types: hex and Torx Socket profile: 6-point Storage: SOS laser-cut foam tray Construction: chrome-vanadium socket bodies, tool-steel bit tips Made in Slovenia, since 1919 Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race 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.
