The Santa Cruz Bronson GX AXS is a trail-slaying machine designed for riders who thrive on variety — from smooth, flowy descents to gnarly, technical climbs. With a Carbon C frame, this Bronson brings the unbeatable balance of durability and lightweight agility. Its MX wheel setup pairs a 29” front wheel for plowing over rough terrain with a nimble 27.5” rear for quick, playful handling. Built around the VPP™ suspension platform with 150mm of rear travel and a Fox 36 Float Performance Elite fork, this Bronson delivers confidence on every line. Wireless shifting via SRAM GX Eagle AXS T-Type drivetrain keeps your cockpit clean and your gear changes lightning-fast.
