BMC Speedfox 03 TWO

BMC Speedfox 03 TWO
Shadow Grey


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.

BMC's Advanced Pivot System and Big Wheel Concept bring modern trail design to this capable and fun bike. Triple-butted aluminum tubing makes for a stiff, light frame that will respond when you're up and out of the saddle, while 120mm of front and rear suspension soak up bumps. Shifting is fast and reliable with a Shimano Deore drivetrain, including a Shadow Plus rear derailleur, and there's plenty of braking power from the Shimano hydraulic disc brakes. Alex MD30 rims and Shimano Deore hubs are paired for a durable wheelset, and the rugged tread of the Maxxis Forekaster TBR tires make this bike ready to shred.
