History and Legacy
Unior began as a European forging company shortly after World War I, specializing in metalworking for industrial applications. Over the decades, the company expanded into specialized toolmaking, with a particular focus on high-strength steel components. By the late 20th century, Unior had become a respected global supplier for automotive, industrial, and bicycle tools.
The company’s entrance into the cycling world aligned naturally with its engineering strengths. As modern drivetrains grew more complex and workshop standards increased, Unior’s precision and forging expertise positioned the brand as a trusted manufacturer for professional mechanics.
Today, Unior sponsors WorldTour teams, supplies tools to UCI events, and is widely used by technicians who value consistency and longevity above all else.
Design Philosophy
Unior’s toolmaking philosophy is centered on durability, precision, and professional repeatability.
1. Precision First
Every tool is cut, forged, or machined with tolerances designed for repeat daily use. This reduces wear on components and ensures consistent performance.
2. Longevity & Serviceability
Unior tools are built to last decades. Many include replaceable pins, tips, or inserts, extending their lifespan.
3. Real-World Ergonomics
Handles, grip surfaces, and tool profiles are engineered for mechanics who use them all day—not just occasionally.
4. European Steel & Manufacturing
Most tools are produced in-house in Slovenia using high-grade alloys and advanced forging technology, ensuring consistent quality.
Technology & Innovation
Unior may not always push flashy innovation, but its design improvements are thoughtful and rooted in mechanic feedback.
Pro-Grade Steel Formulations
Tools are forged using chrome-vanadium and chrome-moly steels. These alloys resist bending, wearing, and rounding over time.
CNC Machining for Critical Interfaces
Contact points—such as bottom bracket tools, cassette lockrings, and torque interfaces—are CNC-machined for accuracy.
Ergonomic Handles
Rubberized handles on pliers, wrenches, and screwdrivers strike a balance between comfort and longevity.
Service-Friendly Tool Designs
Chain tool pins, nipple wrench heads, and punch components are replaceable, reducing long-term ownership costs.
Modular Workshop Systems
Unior offers:
- Pro mechanic stands
- Portable workstations
- Modular tool storage
- Race day kits
These systems support mechanics who travel or maintain structured workshops.
