Product Info
You've heard "when in doubt, take a Bronson out", but what if the first clause is simply obliterated? The Santa Cruz Bronson 5 CC X0 AXS Complete Mountain Bike is the next evolution of a storied lineage, a genre-spanning all rounder with a wild side that begs to be let loose. The secret sauce lies in a new approach to mixed wheel geometry. Santa Cruz has crunched the numbers and tweaked the Bronson geo with longer chainstays, slacker head tube angles, and a subtle shift in shock positioning to reduce anti-squat for more balanced, intuitive ride. The result is a bike that attacks both the climb and the descent with maximum confidence. This build features the latest Fox Factory suspension, hard stopping SRAM Maven Silver brakes, and the incredible SRAM XO AXS Transmission drivetrain for crispy clean wireless shifting. Yeehaww!

Key Features
Carbon CC Frame – Santa Cruz's highest level of carbon fiber frame construction, CC carbon is not only extremely lightweight and strong, but it comes with a lifetime warranty. The durability, feel, and performance of carbon is unmatched in the mountain bike world, and Santa Cruz are at the top of the game.
Travel – 160mm Front / 150mm Rear
Wheel Size – Mixed Wheel (29" Front / 27.5" Rear)
Updated VPP® Suspension – VPP is based on the patented principle of having two short links rotating in opposite directions. This system provides huge design flexibility, allowing Santa Cruz to manipulate shock rates to the intended purpose and character of each model; from short travel endurance bikes to World Championship winning DH machines. This re-configured layout improves pivot placement and lowers anti-squat for a smoother and more efficient ride.
The Glovebox™ – Seal whatever you want to carry on your ride inside your downtube. Secure and easy to access, the Glovebox™ has a Tool Wallet and Tube Purse inside, to help organize your stuff too. Simply cavernous!
Proportional Chainstay Lengths – With rear ends that match the size range, this bike's geo and ride quality is the same for all riders.
Integrated Flip Chip for High / Low Geometry Setting
