The Bronson continues to close the gap between trail and all-mountain bikes, to boost the stoke factor on every ride - no matter what the terrain. "When in doubt, take a Bronson out" has never been more true, as the mixed-wheel Santa Cruz Bicycles Bronson 4.1 CC X0 AXS Complete Mountain Bike retains the most-versatile title for another year. The funbike flickability is still here, but now you can hit everything faster, with more traction and speed. This build features all new SRAM Code Silver Stealth brakes and the incredible SRAM Eagle AXS Transmission, a revolutionary new design which ditches your trusty derailleur hanger to mount directly to the frame. Engineered for maximum durability, the new derailleur shifts better under load and features a modular, servicable design for easier repairs. There's no contest, this is hands down the best Bronson yet!
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.
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.
Rockshox Super Deluxe Ultimate Rear Shock – Designed for the latest hard-hitting enduro and trail bikes, Super Deluxe Ultimate features the ride-tuning abilities of an air spring with both compression and rebound adjustment to fine tune to any trail. With a solid threshold adjustment for pedaling performance and Maxima Plush fluid for a buttery smooth feel, riders can now easily dial in a podium-worthy ride.
Shock Adjustments – Air Spring Pressure / Low-Speed Compression / Rebound
148mm Rear Axle Spacing
Internal Dropper and Brake Cable Routing
Threaded Bottom Bracket
Integrated Flip Chip for High/Low Geometry Adjustment
Molded Rubber Swingarm and Downtube Protection
RockShox Lyrik Ultimate – Built on a deep foundation of adventure, Lyrik is the most versatile fork in the RockShox lineup. With the perfect range of travel for an all-mountain workhorse, Lyrik prioritizes weight while maintaining that all-critical stiffness and prowess on the descents.
SRAM X0 Eagle AXS Transmission – The next generation SRAM Eagle Transmission is a radically robust, fully integrated and interdependent wireless drivetrain. Built around the universal constant of the wheel axle itself, the Full Mount hangerless attachment creates a far stronger connection to the frame with a super tough derailleur. Shifting under load is made possible due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The new AXS Pods are extremely ergonomic and highly customizable, so shifting gears is light and intuitive.
SRAM Code Silver Stealth – SRAM's legendary, full-powered brake now features a new technology to improve your cockpit aesthetic: Stealth. The all-new lever body design brings the hose closer to the bar, allowing for a sleeker, more modern ride. The proven internals remain the same, with SwingLink driving its signature feel.
SRAM HS2 Rotors – When it comes to heat dissipation, and therefore power, thicker is better. SRAM's new HS2 rotors are 2.0mm thick, helping them avoid heat fade and maintain their power on long descents.
Mixed Wheel Sizing (S-XL Sizes) – The mixed "mullet" wheel sizing of top level racers has trickled down to the rest of us: with a 29" wheel up front for maximum grip and rollover clearance, you'll have a smoother and more solid stance through rough stuff and turns. The smaller 27.5" rear wheel helps you initiate those turns, while keeping the rear end maneuverable and out of your shorts.
RaceFace ARC Offset 30 Rims Laced to Industry Nine 1/1 Hubs – Bomber 6069 aluminum rims on Industry Nine's storied hubs: these wheels are meant to take a beating. They're made to handle the toughest trails around without a weight penalty, balanced and incredibly durable.
Maxxis Minion DHF Front Tire – The Minion DHF was designed for the often loose and muddy conditions of aggressive all-mountain terrain. The DHF incorporates ramped knobs for low rolling resistance and channel-cut knobs to increase gripping edges, giving straight-line control and precise cornering.
Maxxis Minion DHR II Rear Tire – A real rider's tire choice, these Minions bring a mix of rolling resistance, wear, and performance that can't be beat.
