Short 17-piece Combination Wrench Set

A combination wrench set covers the fasteners that a bike-specific kit doesn't reach: small accessory hardware, older builds with non-metric-bike-standard sizes, racing-team service kits, anywhere a quick open-end or box-end is faster than a ratchet-and-socket. The Short 17-piece Combination Wrench Set 125/1MS is the compact version of our full combination set, sized for tight access where a long handle would foul on a frame tube or crank arm.

The 17 sizes cover 6 mm through 22 mm in 1 mm increments: 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 mm. That range covers every standard bicycle-component fastener and most accessory hardware. The metal indexing stand keeps the wrenches organized and visible at a glance; a workshop habit that saves the "where's the 14?" hunt.

Why short-handle

The shorter handle helps where the access angle is limited. A typical example: tightening the rear-axle nut on an older horizontal-dropout frame, where the long-handle wrench's swing is blocked by the chain stay. The short handle has enough leverage for hand-torque on bicycle-standard fasteners (well below the breakaway torque that would call for the 1/2" ratchet), and the shorter swing fits the space.

For sizes where leverage matters more than access (the larger end of the set, working a 22 mm fastener under full torque), the longer-handle 125/1L set is the complement. Most working shops own both lengths; the short version sees more use because most bicycle fasteners are at the smaller end of the size range.

Why a combination wrench (not just sockets)

A combination wrench has an open-end on one side and a box-end on the other. The open-end accepts a fastener that's partially blocked at the top (e.g., a pinch-bolt where the socket can't pass over a stud or extension). The box-end gives full 360° engagement on the fastener flats for higher-torque work. The combination of the two means one wrench covers both access patterns; you don't need to choose between an open-end set and a box-end set.

The 12-pt box-end at the closed side accepts the fastener at 30° increments, which gives a wider range of starting angles than a 6-pt box-end. Useful in tight quarters where you can't get a clean 60° engagement.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 125 combination wrench family is forged from chrome-vanadium at Zreče, machined to spec on-site, and finished through Unior's standard chrome-plating process. Same construction across the long-handle and short-handle variants; only the handle length differs.

Pro tip from our mechanics

A working shop that has a combination-wrench set and a socket-and-ratchet set ends up using each for different work without thinking about it. The combination wrench is faster on hand-torque fasteners in known sizes; the socket-ratchet is faster on higher-torque or unknown-size fasteners. The indexing stand keeps the combination set organized for the quick reach.
