Santa Cruz's most notorious thriller, the Bronson, is ready for action no matter what role it's cast into. The Bronson has the biggest personality in our range. From flat-out on the trail to fully flat over a table, each new generation redefines expectations of what a 150mm bike can do.

The new lower-link mounted shock configuration opens up greater possibilities for maximum bump performance, a supportive mid-stroke, and a barely detectable bottom out. It’s like our most capable all-around bike just had a set of afterburners bolted on.

With 150mm of VPP travel on 27.5-inch wheels, the Bronson continually rides the sharp edge between agility and stability. Ideal for negotiating tech-gnar one moment and fast flowing terrain the next, the 160mm fork travel and 65-degree head angle ensure handling remains refined. Meanwhile, the redesigned, one-piece swingarm keeps the rear wheel tracking on point, however twisted you get.

There’s plenty of room to run up to 2.8-inch tires on plus rims. We offer build kit options for “regular” 27.5 and Plus-size, using 2.6 tires. It feels like the sorta big is the sweet spot between the Velcro-like traction of plus tires and the traditional feel of a supportive casing on standard-width tires.

Its versatility makes Bronson the go-to choice for those seeking a skeleton key to unlock unfamiliar trails.

Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:

Shifting Performance
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.

Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.

Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.

Wider than standard yet narrower than fat, plus-size rims and tires hit the sweet spot in grip, stability, and speed, giving you more confidence on technical terrain. Compared to a standard tire you’ll feel grip in places you wouldn’t expect thanks to a bigger contact patch and greater rollover clearance. More air volume allows lower tire pressures which softens bumps and increases float on sand or snow. Whether you’re a novice or an expert, the benefits of plus-size tires and rims will amplify your mountain biking fun.

A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.

Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.

Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
