Trail riders are a demanding bunch; asking to effectively balance swift uphill performance with ripping downhill capability, tackle switchbacks, and withstand repeated punishment. It's an ambitious order. That's why we re-engineered the Speedfox to deliver on all fronts. Lightweight, tough, and versatile, yet still eager for all-out speed. BIG WHEEL CONCEPT (BWC) - Purpose-built 29er geometry and cockpit designs make our 29" bikes nimble, stable, and incredibly efficient. ADVANCED PIVOT SYSTEM (APS) - APS dual-link suspension technology allows you to pedal efficiently, brake hard, and charge rough terrain without compromise. IP CABLE ROUTING - The semi-integrated cable routing delivers a clean look and easy maintenance. INTEGRATED PROTECTION - Molded downtube and chainstay guards keep your frame safe from impacts in a refined design package. MUD-FLAP/HIDDEN LINK - Hides all cables between the rear triangle and the mainframe; keeps bearings free of grime.
