Multitool EURO17

The 17-function on-bike multitool with the bit selection of a shop hex and Torx set. 2, 2.5, 3, 4, 5, 6, 8 mm hex, T10 and T25 Torx, a #1 Phillips and 1.0 × 5.0 mm flat screwdriver, a chain tool, Schrader and Presta valve core tools, and spoke wrenches for 3.3 mm, 3.45 mm, and DT Swiss nipples. The kit that covers everything from a trailside derailleur adjustment to a chain repair on a multi-day ride.

Each bit on the EURO17 has chrome-plated chrome-vanadium shanks with black-oxide tips for corrosion resistance and a tight fit to the recess. The bit-quality choice matters more on a multitool than on a shop tool, because trailside repairs happen at the working-torque limits the multitool's small handle can deliver; a sloppy fit will round a fastener at exactly the moment you have no spare tool to switch to.

The chain tool inside the EURO17 is the load-bearing function. The EURO17 is built from chrome-vanadium, molybdenum-vanadium, and chrome-silicon-vanadium steels, and nowhere does that matter more than in the breaker — the on-ride counterpart to Unior's standalone chain-rivet pliers. A multitool chain tool that bends under load is not a chain tool, it's a chain-tool-shaped paperweight. The EURO17's chain tool is the version that survives the breaks it's asked to make.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The EURO line is one of the few mid-price multitool families produced entirely in Europe; most multitools in this price band are made in Asia regardless of brand badge, and the cost difference shows up in the bit-to-recess fit when you need the tool to work hardest.

Pro tip from our mechanics

A multitool's bits will wear before the body does, especially the 4 and 5 mm hex tips, which see the most engagements on a typical ride (stem face plates, water-bottle cages, brake-lever clamps for a quick angle adjustment mid-ride). When the 4 mm or 5 mm tip starts to feel loose in a fresh bolt, the rest of the tool's still good, but those two bits need to be the ones you watch for wear.

FAQ

What tools are included in the Multitool EURO17? Seventeen functions: 2, 2.5, 3, 4, 5, 6, and 8 mm hex keys; T10 and T25 Torx; a #1 Phillips and a 1.0 × 5.0 mm flat screwdriver; a chain tool; Schrader and Presta valve core tools; and spoke keys for 3.3 mm, 3.45 mm, and DT nipples.

How much does the EURO17 weigh? 184 grams (about 6.5 oz) — jersey-pocket weight for a tool that carries a full 2–8 mm hex range plus a chain breaker.

Will the chain tool work on a 12-speed chain? Unior does not publish a chain-speed rating for the EURO17's integrated chain tool. It presses standard chain pins for trailside repairs; verify pin compatibility before relying on it with 12-speed Campagnolo or SRAM AXS Flattop chains, and carry a spare quick link to rejoin a repaired chain.

Where is the EURO17 made, and what warranty does it carry? The EURO17 is designed and produced in Slovenia by Unior, a European hand-tool manufacturer since 1919, and it is covered by Unior's lifetime warranty.
