Santa Cruz Bronson 4.1 C GX 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. This frame uses the legendarily-durable Santa Cruz C carbon (including a lifetime warranty), and is compatible with both coil and air shocks, while size-specific chainstay lengths on every frame size make sure each rider gets the best out of their Bronson.
The Bronson 4.1 C GX AXS Bike is equipped with the new SRAM GX AXS Transmission wireless electronic drivetrain, setting a new standard for robustness, superior shifting, and easy setup, all while leaving a bit left in your bike budget. The versatile and adjustable FOX 36 Float Performance Elite 160mm fork and a RockShox Super Deluxe Select+ rear shock team up to soak up technical terrain. 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, a set of high-powered SRAM Code RS Stealth brakes provide exceptional braking control, while a RockShox Reverb Stealth Dropper Post makes maneuvering through technical sections a breeze.
