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 sponsors professional road and mountain-bike race 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.
