Bronson 5 MY25

2024 - 2025

THE CORE ALL-ROUNDER WITH A WILD SIDE.

When you can only have one bike, and your mission is to ride that bike into oblivion, then this is the one. From manicured bike parks to blown out loamy berms, alpine lines to backyard trails, the Bronson is as at home in the air as it is in the dirt. For the rider with a Peter Pan disposition or who wants to get into a pan flat tabletop position, the Bronson encourages bad behavior.

FAQs

The Bronson has a 180mm rear brake post mount, so this is the smallest compatible rotor. Maximum rotor size is 223mm

The Bronson is designed around modern 55mm chainline cranks/drivetrains.

The Bronson Carbon C is compatible with all 1x MTB drivetrains, and includes full "tube-in-tube" routing for cable-actuated derailleurs. Our top end Bronson Carbon CC is wireless drivetrain only, saving weight and eliminating unused cable ports. All models are compatible with cable-actuated dropper posts.

Check out our Dropper Post Calculator here, where you can calculate which specific post will fit for your frame size and saddle height.

The Bronson comes with two bags - a tube purse and a tool wallet. You should be able to fit a superlight tube, a small pump, tire lever, and misc odds and ends in these two bags.

CC frames use the very best materials and production processes available. Our C Carbon frames have the same features but the trade off for a little less $ is a little more weight. Both versions are made in our own factory, are just as strong and stiff as one another, and have a lifetime warranty. The CC frames are specifically designed for wireless drivetrains, while the C frames are compatible with both wireless or cabled drivetrains.

The frame is UDH-compatible, but comes with our own machined aluminum hanger. You can replace it with another Santa Cruz hanger or a SRAM UDH.

You should definitely try both, but your starting point depends on terrain. For flatter terrain, try Hi setting. The quicker steering and slightly more forward weight bias will provide more responsive handling. For terrain with steeper descents, try starting in Low. This shifts your weight slightly down and rearward, providing a bit more confidence and control when pointed down hill.

The Bronson fits most shocks on the market, including coil or large-volume air shocks. The shock dimensions are 230x57.5mm with 30x8 rear hardware and 40x10 front hardware.

Designed for 27.5" x 2.5" max

This bike uses integrated headset cups. The upper up is 41mm and the lower cup is 52mm. The SHIS name is IS 41/28.6 IS 52/40. For Chris King this is a DropSet.3

No, the Bronson is built exclusively for MX wheels (29" front, 27.5" rear). It is not designed to accept a 29" rear wheel in any configuration.

Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting. We recommend the the OneUp Chainguide or Bashguide V2 , but most guides that follow the ISCG-05 standard should fit.

The Bronson geometry is based off of a 160mm fork with a 44mm offset.
