Overview
The 2026 Santa Cruz Bronson is Santa Cruz’s MX (mixed-wheel) trail bike, running a 29″ front wheel paired with a 27.5″ rear for a combination of front-end rollover speed and rear-end playfulness. With 160mm of front travel and 150mm of VPP rear suspension, the Bronson shares the Hightower’s travel numbers but delivers a distinctly different riding experience thanks to the mullet wheel configuration. Where the Hightower is about pure speed and efficiency, the Bronson is about fun and versatility.

The Bronson features the same proportional geometry philosophy as the rest of the Santa Cruz lineup, with size-specific chainstays (437-448mm) and seat tube angles that steepen on larger frames (77.6° SM to 78.4° XXL). A 64.2° head angle matches the Hightower, and reach ranges from 435mm (SM) to 525mm (XXL). The smaller rear wheel lowers the rear of the bike slightly, creating a natural nose-up feel that encourages playful riding and helps get the front end light over features.

Geometry Analysis
The Bronson shares many geometry numbers with the Hightower — the same 64.2° head angle, identical reach figures, and the same progressive seat tube angles. The key differences come from the mixed wheel setup: the slightly longer chainstays (437-448mm vs 434-445mm on the Hightower) and marginally longer wheelbase accommodate the MX configuration while maintaining balanced handling. The 29mm BB drop and 344mm BB height match the Hightower exactly, suggesting Santa Cruz designed the two platforms to feel geometrically similar despite the different wheel sizes. The proportional chainstays grow by 11mm from SM to XXL, maintaining consistent rear-end character across the size range.
Ride Characteristics
The Bronson brings a distinctly playful character to Santa Cruz’s trail lineup. The 27.5″ rear wheel makes the back end noticeably easier to manipulate — manuals, bunny hops, and getting the rear wheel off the ground all feel more natural than on the 29″ Hightower. The 29″ front wheel maintains rollover speed and stability, giving you the best of both worlds. On descents, the Bronson feels more flickable through tight, twisty sections where the Hightower might feel like a bigger bike. The VPP suspension provides the same efficient pedaling and progressive bump absorption as the rest of the Santa Cruz lineup. Climbing is slightly less efficient than the Hightower due to the smaller rear wheel, but the difference is marginal with modern MX geometry optimization. Where the Bronson really separates itself is on playful, feature-rich trails where you want to pop off every lip and slash through berms.

What’s New vs Previous Generation
The current Bronson has been optimized for the MX wheel configuration from the ground up, rather than being a converted 29″ frame. The proportional geometry with size-specific chainstays ensures the mullet setup handles consistently across all sizes. Updated VPP kinematics have been tuned specifically for the MX wheel dynamics, and the frame includes internal downtube storage. UDH compatibility for SRAM Transmission derailleurs is standard.
Who Should Consider This Bike
The Bronson is for riders who prioritize fun and playfulness on the trail. If you love popping off features, getting sideways in corners, and value a bike that encourages creative line choices, the Bronson delivers. It’s also an excellent choice for shorter riders who find 29″ wheels feel too large at the back, as the 27.5″ rear wheel improves standover and low-speed maneuverability. Riders who want maximum rolling efficiency and speed should choose the Hightower (full 29″). Those who want more travel for aggressive enduro riding should consider the Nomad.
Comparable Models
The Bronson competes with the Trek Fuel MX, Specialized Stumpjumper 15 EVO, Yeti SB130 MX, Ibis Ripmo MX, and Pivot Switchblade. The MX trail category has grown significantly, and the Bronson is one of the most established players. The Trek Fuel MX runs a similar MX setup with adjustable geometry. The Stumpjumper 15 EVO offers more travel in an MX configuration. The Yeti SB130 MX uses the Switch Infinity platform. Among these, the Bronson’s VPP suspension and proportional geometry are its primary differentiators.

Frequently Asked Questions
What wheel size does the Santa Cruz Bronson use?
The Bronson uses an MX (mixed/mullet) wheel configuration: 29″ front wheel for rollover speed and stability, and 27.5″ rear wheel for playfulness and maneuverability.
What is the difference between the Bronson and the Hightower?
Both have 160/150mm travel, but the Hightower runs full 29″ wheels for maximum speed and efficiency, while the Bronson uses MX (29″ front, 27.5″ rear) for a more playful, flickable feel. Geometry is nearly identical, but the riding experience is distinctly different.
Is the Bronson good for bike parks?
Yes, the Bronson’s MX setup and 150mm of travel make it a capable bike park option that can still be pedaled back to the top. For dedicated bike park or enduro racing, the Nomad (170/170mm, MX) or Megatower (170/165mm, 29″) offer more capability.
Can I convert the Bronson to full 29″?
The Bronson is designed specifically for the MX wheel configuration, and converting to full 29″ would significantly alter the geometry and suspension kinematics. For a full 29″ trail bike, Santa Cruz offers the Hightower with the same 160/150mm travel.
How much does the Santa Cruz Bronson cost?
The Bronson ranges from approximately $4,899 for the GX AXS Carbon C build to $9,749 for the X0 AXS RSV Carbon CC build with Reserve carbon wheels. Frame-only options are also available.
