The Santa Cruz Bronson 5 70 is the gateway to the carbon Bronson: a carbon trail mountain bike with MX wheels, 160 mm of front travel and 150 mm at the rear, made for riders who want to have fun on technical trails without giving up long days in the mountains.
The 70 build goes straight to the essentials: RockShox Lyrik fork, FOX Float Rhythm shock, SRAM 70 Eagle T-Type drivetrain and SRAM DB8 brakes with 200 mm rotors. Reliable, easy-to-live-with parts mounted on the same frame as the most expensive models in the range.
SRAM 70 Eagle T-Type drivetrain
- SRAM 70 Eagle T-Type 1x12 drivetrain with the derailleur mounted directly to the UDH
- 10-52T cassette and 32T chainring: easy gears for steep climbs and range for long transfers
- Solid shifting even under load, ideal when pushing hard on rough ground
- SRAM DB8 4-piston brakes with 200 mm CenterLine rotors front and rear
Bronson 5 Carbon C frame and VPP suspension
- Carbon C frame, the layup Santa Cruz uses to combine toughness, torsional stiffness and low weight
- VPP rear suspension with 150 mm of travel: supple over small bumps, supportive in the mid-stroke and progressive on big hits
- MX setup: a 29" front wheel to roll over obstacles and a 27.5" rear for a more agile bike with extra room between saddle and tyre
- Glovebox in the down tube for a tube, tools and a snack, no backpack needed
- Flip chip to raise or lower the bottom bracket and tune the bike to your trails
- Moulded protection on the down tube, chainstays and shuttle area, UDH derailleur hanger
- RockShox Lyrik Base 160 mm fork with 35 mm stanchions
- FOX Float Rhythm air shock, simple to set up
Wheels and components
- Reserve 30|TR aluminium rims laced to SRAM MTH hubs
- Maxxis Assegai 29" x 2.5" MaxxGrip front and Minion DHR II 27.5" x 2.4" rear tyres, EXO+ casing
- SDG Tellis dropper post and SDG Bel-Air V3 saddle
- Aluminium cockpit with a short stem and Santa Cruz House grips
- Manufacturer's claimed weight: 15.78 kg
Geometry and ride feel
The Bronson 5 pairs a slack head angle with modern reach for confidence when the trail points downhill, while the steep seat angle puts you in the right spot to climb. The 27.5" rear wheel makes the bike quick to change direction and easy to lift off the ground: this is the Santa Cruz trail bike for riders who love to play with the terrain.
Why choose the Santa Cruz Bronson 5 70
- Carbon C frame identical to the one on the top-end builds
- MX wheels and 160/150 mm for playful, confident trail riding
- Durable T-Type drivetrain
- Reliable, easy-to-service components
- Matte Poblano Green finish and Santa Cruz lifetime frame warranty
The Santa Cruz Bronson 5 70 2026 is the most direct way to own a carbon Bronson ready for anything, from an after-work loop to a full day on the trails.
