The Fox 34 Float SC Factory fork and Fox Float SL Factory rear shock provide plush, controlled suspension performance, while the Squidlock remote allows instant adjustment on the fly.
Orbea’s OMX carbon is the pinnacle of carbon fibre engineering, delivering an ultra-lightweight yet incredibly stiff frame. Combined with the Fiberlink system and I-Line shock integration, the Oiz M-Pro maximises power transfer while keeping weight to an absolute minimum.
The patented I-Line system routes the shock lockout cable internally for the cleanest, most efficient design. This means less cable clutter, reduced friction, and ultimate reliability when every second counts.
Occasionally, without notice, manufacturers change product design and/or specifications.
