Multitool EURO13

The 13-function on-bike multitool. Same hex and Torx core as the EURO17, sized down by dropping the secondary spoke wrenches and the larger flat screwdriver. The format for riders who want the full hex span (2 through 8 mm), T10 and T25 Torx, and a chain tool, in a smaller package than the EURO17's full-function envelope.

The bits on the EURO13 are the same construction as the bits on the EURO17 and the standalone shop hex / Torx tools in the Unior line: chrome-plated chrome-vanadium shanks with black-oxide tips. The hex span (2, 2.5, 3, 4, 5, 6, 8 mm) covers every bike-relevant size below the 10 mm Campagnolo crank bolt, which is the size most likely to be omitted from a trail-side kit anyway (Campagnolo crank work isn't a trailside repair).

The chain tool is the same drop-forged body and induction-hardened pin as the EURO17. The EURO13 drops the EURO17's third spoke wrench and the larger flat-blade screwdriver to save weight, keeping the chain tool, valve core tools, and the two most-used spoke-wrench sizes intact.

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 EURO13's bit set is sized down from the EURO17 by dropping functions a typical rider doesn't reach for on a trailside repair, not by dropping the bit-quality standard the rest of the line ships with.

Pro tip from our mechanics

The EURO13 is the kit for riders who do most service at home and only need the on-bike tool for the occasional trail adjustment. If you ride somewhere remote enough that a broken spoke is a multi-hour walk back, the EURO17's extra spoke-wrench size is worth the weight; if you ride somewhere with phone signal and bike-shop coverage, the EURO13's smaller package is what you want.
