Key Features

Developed with input from professional MX riders, this 34-layer carbon fiber frame strikes the ideal balance of flexibility and rigidity for superior comfort, support, and reduced risk of ligament and meniscus injuries.

The frame geometry, designed from extensive 3D scans of athletes, ensures optimal internal volume and hinge width for maximum comfort. Upper and lower frame edges feature soft, flexible transitions to prevent contact with hard carbon surfaces.

Replaceable knee cups combine a polyurethane shell with a Nucleon PLASMA protector for impact protection, flexibility, and scratch resistance.

Strategically positioned patella extensions provide full coverage at any flexion or extension angle.

A low-profile, four-point hinge system mirrors natural knee articulation, with adjustable extension stops (0–30°) for personalized range control.

Replaceable hinge covers create a smooth transition, eliminating snag points.

Nucleon PLASMA, a bio-based viscoelastic material, disperses impact while remaining lightweight, ventilated, and pliable for all riding positions.
