Santa Cruz Bronson 5 C GX AXS
Product Details
Built for riders who refuse to choose between climbing prowess and descending mayhem, the Santa Cruz Bronson 5 C GX AXS is the "one bike" answer to a quiver full of compromises. Its Carbon C frame pairs 150mm of refined VPP rear travel with a 160mm fork, and thanks to a reworked suspension layout with lower anti-squat, it pedals with surprising calm before coming alive the moment gravity takes over.
At the heart of the ride is the mixed-wheel MX setup: a 29" front wheel that rolls over chunder and holds a line through rough sections, matched to a nimble 27.5" rear that snaps out of corners and flicks off lips with ease. It's a combination that rewards playful riders while still keeping things planted when the trail gets serious.
Suspension duties fall to FOX's Performance Elite kit—a 36 fork running the Grip X2 damper up front and a Float X out back—giving you a supple, controlled feel whether you're soaking up braking bumps or landing deep into travel. Shifting comes courtesy of SRAM's wireless GX Eagle AXS Transmission, with crisp electronic shifts across a 10-52T range that flattens steep climbs. SRAM Maven Bronze brakes haul you down from speed with genuine authority, and the Reserve 30|SL AL wheelset—wrapped in grippy Maxxis Assegai and Minion DHR II rubber—keeps traction high on loose, rocky, and off-camber ground. A OneUp dropper rounds out a cockpit that's ready to session from the first lap.
From bike park berms to backyard jump lines to all-day backcountry missions, the Bronson 5 C GX AXS is happiest when you're pushing the pace and looking for the next thing to send.
