Santa Cruz Bronson 4.1 CC X0 AXS Bike
Ready for Action
Whether you’re hucking it to flat at the bike park, tackling big terrain on an enduro course, or just hitting top speeds on aggressive trails, the Santa Cruz Bronson has the big hit capability you want, and plenty of pedaling efficiency that you need to earn your turns. Using 150mm of tuned VPP™ rear suspension with a 160mm fork and an MX mixed wheel size platform, the Bronson blends big capability with a playful, maneuverable feel. Using Santa Cruz’s legendary top-end CC carbon, the stiffness of the Bronson is size-specific, delivering the right ride quality for every rider, while size-specific chainstay lengths on every frame size make sure each rider gets the best out of their Bronson.
The Bronson 4.1 X0 AXS Bike is equipped with SRAM’s X0 Eagle AXS Transmission wireless electronic drivetrain, setting a new standard for robustness, superior shifting, and easy setup. This build is decked out with a Santa Cruz 35 Carbon Bar, and spins on Industry Nine 1/1 hubs laced to RaceFace ARC 30 Offset Rims providing quick freehub engagement and high-end durability. To control speed through the fastest descents, the high-powered SRAM Code Silver Stealth brakes provide exceptional braking control, while a OneUp V2 Dropper Post makes tackling those techy sections a breeze.
