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.

Transmission SRAM Eagle - plus solide, un changement de vitesse optimisé, sans fil

La nouvelle génération de transmission SRAM Eagle, qui équipe désormais nos modèles en carbone CC, est résolument robuste, parfaitement intégrée et fonctionne sans fil. Conçue autour de la constante universelle qu'est l'axe de la roue arrière. Le montage direct, sans patte de dérailleur et un dérailleur totalement retravaillé offre un ensemble plus sûr, à la robustesse sans précédent. Le changement de vitesse sous la contrainte est désormais possible grâce à la technologie X-SYNC et la cartographie de la toute nouvelle cassette, créant ainsi un passage des rapports extrêmement fluide même lors des plus puissantes accélérations. Les nouveaux Pods AXS sont parfaitement ergonomiques et ajustables dans toutes les directions. Les changements de vitesse sont alors faciles et intuitifs. Il s'agit tout simplement de la transmission la plus avancée qui soit, surement aussi solide que la montagne sur laquelle vous roulerez.

Taille de cadre

Si vous vous trouvez entre deux tailles recommandées, l'idéal est bien sûr d'essayer les deux. Mais à défaut, vous pouvez aussi étudier les mesures de reach et de stack de votre vélo actuel pour les comparer au modèle qui vous intéresse et ainsi vous faire une idée des dimensions qui vous conviennent. Si vous n'avez pas la possibilité d'essayer le vélo, considérez ce qui suit.

Préférences personnelles

un cadre plus grand sera plus stable et offrira plus de place pour bouger sur le vélo sans influer l'équilibre général. Une taille plus grande place la roue avant plus loin devant vous, donnant un sentiment de sécurité, mais demande aussi plus d'effort pour transférer les masses et déplacer le vélo. Réfléchissez à votre style et la façon dont vous aimez rouler, si vous préférez un vélo plus actif et intuitif ou au contraire plus rapide et plus stable. Piloter un vélo plus grand vous demandera forcément plus d'efforts.

Morphologie

Tous les corps n'ont pas les mêmes proportions pour une même taille. Si vous avez de longues jambes et un torse plus court que la plupart des personnes de votre taille, vous privilégierez surement un vélo plus petit que la taille recommandée. Si au contraire vous avez de long bras et un corps plutôt grand, vous préférerez surement une taille plus grande.

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.
