C Carbon Frame
The Bronson 4 features Santa Cruz’s proprietary C Carbon frame, a strong yet lightweight material that balances stiffness, durability, and comfort. The frame's aggressive geometry is built around mixed wheels (29" front, 27.5" rear) to offer a playful yet stable ride.

The frame integrates VPP (Virtual Pivot Point) suspension, a hallmark of Santa Cruz bikes, offering excellent pedaling efficiency and supple rear travel for descending. With internal cable routing, a threaded bottom bracket, and sleek aesthetics, the Bronson 4’s frame is both performance-driven and easy to maintain.
Fox Performance 36 Fork
The front suspension is handled by the Fox Performance 36, a 160mm travel fork designed for aggressive trail and enduro riding. Its 36mm stanchions provide stiffness and precision, ensuring confidence through rough terrain and technical descents. The Grip damper allows for easy adjustability, letting riders fine-tune rebound and compression settings to match the trail conditions.
RockShox Super Deluxe Select+ Shock
The Bronson 4’s rear suspension is powered by the RockShox Super Deluxe Select+ shock, delivering 150mm of plush, responsive travel.
