OSX Handlebars - 31.8mm Clamp, 35mm Rise

The benchmark in alloy handlebar performance.

The OSX is the evolution of Chromag's beginnings in handlebar design—shaped by over 20 years of refinement, rider feedback, mechanical testing, and real-world testing. From the start, the goal has been to build strong, reliable handlebars with a precise and comfortable ride feel, and the OSX is the result of that commitment.

Crafted from 7000-series alloy using variable butting and advanced heat treatment techniques, the OSX achieves an ideal balance of strength, compliance, and control. Over the years, we've continuously improved its durability, pushing its fatigue life well beyond industry standards, while maintaining the responsive handling that riders expect.

With a 31.8mm clamp diameter, an 8° backsweep / 5° upsweep geometry, and a full 800mm width (trimmable), the OSX is the handlebar we’ve spent decades perfecting—built for riders who demand confidence, precision, and time-tested performance on any terrain.
