X1 Fiber-X

Rim Size
Freehub Body

The Story:

Tough. Tuned. NEW.

Possessing twice the tensile strength of High-Modulus carbon fiber, Fiber-X employs damping characteristics to deliver a trail-tuned ride while increasing durability - durable enough to withstand a double impact of 120 joules at the same location. The Fiber-X material is blended into all of Mercury’s X-Series wheels and is visible by its distinguishable silver stripe. Rim profiles feature an optimized trapezoidal profile that funnels trail input into the elastic material to dissipate energy and avoid failure. All X-series wheels feature off-set rim beds, embossed logos, hook-less beads and are available in widths ranging from 25~40mm internally. At their center, is Mercury’s proprietary Axis straight-pull hub featuring triple stepped 6 pawl system to deliver 3.5° of engagement. All current wheel diameters, axle sizes and freehub standards are supported.
