If in doubt, take a Bronson out

You know what’s hard about choosing what model of Santa Cruz suits you? It’s having to narrow down what kind of riding you want to do. But what if you don’t want to be pinned down by labels? What if you want to just be a mountain biker in the broadest sense of the word? What if you want to choose how you ride rather than what to ride? If this sounds familiar, then try a Bronson.

Our demo crew have a saying, ‘If in doubt, take a Bronson out’. The 150mm-travel bike can go deep on any landing and the VPP™ suspension design makes sure that there’s no wasted energy when heading back up for another go.

If you value style at speed or want to have fun feeling fast, then mixed wheels (29” up front, 27.5” out back) show that the spectrum is a loop not opposite points on a scale. The larger front wheel provides more traction and stability that’ll make you feel more confident squaring off the turns and diving for the inside lines. But a 27.5-inch tire in the rear means this bike still loves getting up on the back wheel and into the air.

From flat out on the trail to fully flat over a table, each generation of Bronson rider redefines expectations of what a mountain biker is.

SRAM Eagle Transmission - robuster, geschmeidiger, kabellos

Die nächste Generation des SRAM Eagle-Getriebes findest du an unseren neuen CC-Modellen. Sie ist eine radikal robuste, innovativ integrierte und vollständig eigenständige, kabellose Schaltung. Die Full-Mount Aufhängung sitzt direkt auf der Hinterrad-Achse und schafft eine wesentlich stärkere Verbindung mit dem Rahmen, während das besonders robuste Schaltwerk eine noch nie dagewesene Belastbarkeit bietet. Geschmeidige Schaltvorgänge sind durch die Kombination aus X-SYNC-Technologie und Kassetten-Mapping selbst unter Vollast möglich. Die neuen AXS Pods Schalthebel sind extrem ergonomisch und hochgradig anpassbar. So wird das Schalten leicht und intuitiv. Es ist einfach die fortschrittlichste Gangschaltung und fast so robust wie die Berge selbst.

Die richtige Rahmengröße

Wenn Du zwischen zwei Größen liegst, empfehlen wir, dass Du die beiden verschiedenen Größen testest. Als Anhaltspunkt kannst Du die Reach- und Stack-Werte mit Deinem aktuellen Bike oder anderen bekannten Bikes vergleichen, auf denen Du Dich wohl fühlst. Wenn keine Testfahrt möglich ist, kannst Du Dich auch an den folgenden Tipps orientieren:

Persönliche Vorlieben

Mit einem größeren Rahmen hast Du mehr Stabilität und Souveränität. Außerdem erhältst du mehr Bewegungsfreiheit im Rad, bei weniger Einfluss auf die Balance. Beim größeren Rahmen ist das Vorderrad etwas weiter vorne, was zusätzlich Sicherheit und Stabilität bringt. Daher bedarf es mehr Körpereinsatz und eine etwas aktivere Fahrweise, um das Bike zu führen. Kleinere Bikes fahren sich agiler und reagieren schneller auf den Input des Fahrers. Überlege Dir, was besser zu Deinem Fahrstil passt. Soll das Bike agil und aktiv sein? Oder eher spurtreu und souverän. Willst Du mehr oder weniger Einsatz zeigen, um das Bike im Trail zu führen?

Körperproportionen

Auch bei gleicher Körpergröße sieht jeder Mensch anders aus. Wenn Du einen verhältnismäßig kurzen Oberkörper und lange Beine hast, würden wir zur kleineren Rahmengröße raten. Bei langem Oberkörper und langen Armen, solltest Du eher zum größeren Rahmen greifen.

Design Details

Upper link and shock with 150mm of travel

Design Details

1 / 6

150mm VPP™ travel

The 150mm-travel bike has enough travel to go deep on any landing and the VPP™ suspension design makes sure that there’s no wasted energy when heading back up for another go.

Mix of both worlds

The mixed wheel configuration of a 29-inch wheel up front provides traction and stability, while the 27.5" rear wheel allows for quick back wheel steering and lifting.

Geo to match

The Bronson's chainstay length is matched to frame size so every rider, no matter their height, gets the same balanced geometry and bike fit.

Coil or air

The Bronson frame fits all sizes and types of rear shocks.

Made to last many lifetimes

The legendary Santa Cruz fit, finish and quality construction put this into a league of its own. The frame, bearings and optional Reserve wheels come with a lifetime warranty and any service is easy to do with our Rider Support pledge.

Tough Carbon Frame

Why scrap a frame when a simple bearing service can make one last a lifetime? That's our stance on sustainability at least, and it's why our carbon fiber doesn’t just mean lighter, it means tough as hell, lifetime warranty and crash replacement support.

FAQ's

Can I put a 27.5 front wheel on the Bronson?

These bikes are designed specifically to use mixed wheels. We do not recommend a 27.5 front wheel for geometry reasons. The XS size is the exception as it's designed for 27.5".

Do all sizes use MX wheels?

The XS size Bronson uses 27.5" wheels front and rear. All other sizes are MX

I see there are different chainstay lengths for each size bike. Can I buy a different swingarm to customize the length on my bike?

The chainstay length change occurs in the front triangles- we vary the pivot locations fore and aft to achieve the different lengths while using a single size swingarm. So no- you cannot get the chainstay length of the small on your size large, for instance.

I'm coming from a 27.5 bike - what will feel different with MX? Any setup tips?

An MX bike will definitely handle differently than a full 27.5 bike. The main difference you'll feel is a more stable and confident front end. The turning will be a bit slower than a 27.5, but the payoff is a more secure feeling in corners and more traction. Due to the taller front axle height and improved roll-over of the large wheel, your chances of stuffing the front wheel or going over the bars is vastly diminished. Use this security to ride challenging terrain with a more aggressive and dynamic body position.

I've been riding 29ers for a while - what will feel different with MX? Any setup tips?

29" bikes provide a ton of front wheel grip- this is partially due to the front wheel itself, but also due to the axle height of the rear wheel which works to keep the front end weighted. This creates a natural position on lower-angle terrain but requires body position and/or setup adjustments to achieve any sort of rearward bias.

On an MX bike, the bias is more rearward. This gives a very natural feeling on steep descents, but requires some body position and setup consideration for a balanced feel on flatter terrain. Compared to a 29er, a slightly lower handlebar and a more forward-biased suspension setup will make an MX bike feel more like what you're used to. Additionally, using the Hi BB setting will lend itself to a more front biased feel. Using these tuning parameters will help you find the sweet spot for your terrain and preference.

You'll know you have it dialed when it feels like you're never making large bodyweight shifts to either lift the front end or keep it stuck to the ground.

What fork offset is the recommended?

The Bronson comes with 42-44mm offset forks, and this is what we recommend for optimal handling. The size XS come with a 37mm offset 27.5" fork

What's the largest rear rotor that will fit on the Bronson?

The minimum is 180mm (direct mount) and the largest is 223mm

Why are there two different measurements listed for BB Drop?

BB drop is the measurement between the center of the bottom bracket and the front and rear axles. Because the Bronson (S-XL) comes with two different wheel sizes the BB drop is greater up front.

Why MX (Mixed Wheels)?

Mixed wheels provide the stability and traction of a 29" front wheel with the agility of a 27.5" rear wheel. The smaller rear wheel and its comparatively lower axle height allows the rider to more easily unweight the front wheel- this makes for confident yet agile handling on the steepest of descents.
