BMC Speedfox 03 ONE

BMC Speedfox 03 ONE


Trail riders are mountain biking’s most demanding crowd. They require a bike to effectively balance fast climbs, rip the descents, tackle tight switchbacks and withstand repeated daily punishment. It’s an ambitious order. We love that. We re-engineered the Speedfox to be the elusive ‘quiver killer’. It is light, sturdy, capable of adventure, yet still eager for all-out speed. A ride for any trail, anywhere. The Speedfox’s premium frame, with its state-of-the-art geometry and low standover height, delivers maneuverability around challenging features yet confident, straight-line stability. Whether that’s going up or coming down. Integrated protection and internal routing make the bike look sharp, but also keep cables and parts safe during long, hard rides. The Speedfox is the new apex predator in mountain biking’s most demanding category.

The Speedfox 03 ONE features the trusty Rockshox Reba SL fork with 120mm of travel, capable of tackling a wide variety of all-mountain terrain. A Fox Float rear shock complements the Advanced Pivot System (APS) design, allowing suspension activation without compromising the power you're putting into the pedals. A SRAM NX drivetrain and Alex MD30 rims wrapped in Maxxis Forekasters round out the carefully-chosen specs.
