The Santa Cruz Bronson R is the perfect fusion of trail playfulness and all-mountain muscle. Designed around a Carbon C MX frame with a burly 150mm VPP™ rear travel and a 160mm RockShox Lyrik Base fork, it’s a beast on descents and a rocket on climbs. The reliable SRAM NX Eagle 12-speed drivetrain and SRAM DB8 Stealth brakes with dual 200mm rotors offer consistent control and confidence on technical terrain. Rolling on Reserve 30|TR AL or Raceface AR30 rims paired with grippy Maxxis Assegai and Minion DHR II tires, the Bronson R delivers stability and precision where it counts. Topped off with a SDG Tellis Dropper, Fizik Monte or SDG Bel-Air V3 saddle, and Burgtec cockpit, this rig is ready for rowdy adventures.
