Not to be typecast

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 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 it the go-to choice for those seeking a skeleton key bike to unlock unfamiliar trails with ease.

Tech Support

The geometry chart shows two settings- how do I adjust that?

There's a "flip chip" on the lower link where the shock mounts.  Just remove the lower shock bolt and flip the chips to the setting you desire

Can I mount a chainguide to my bike?

Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting. Most chainguides on the market that are made for this standard should work.

Can I put a front derailleur on?

No, this bike is not compatible with front derailleurs.  

I want to put the shock from my old bike on there, can I do that?

We always recommend the stock shock, as we've spent a lot of time tuning for each particular frame. But if you must, these are the specifics you need to keep in mind:
210x55 Metric shock
30x8mm rear hardware (bearing compatible) 20x8 front hardware
Note- Fox Float X2 and Cane Creek Double Barrel Air will not fit in the Bronson/Roubion 

Is this bike coil shock compatible?

A coil shock will fit in the Bronson, but we recommend an air shock. While progressive, the suspension is biased more towards air shocks and not quite progressive enough to work well with a coil in our opinion.  

What kind of headset does this bike use?

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.

What kind of rear brake mount does it use?

This bike uses a 180mm post mount. You cannot run a smaller rotor than that. If using 180mm rotor, your caliper will bolt straight to the mount. For 200 or 203 rotors you will need a 20mm or 23mm Post Mount adapter

What size seatpost does the Nomad/Bronson use?

31.6mm.  We spec/recommend the Reverb without the Connectamajig to maximize the amount of seatpost insertion available.  

Where can I demo the newest model of this bike?

We’ll have the newest version available for demo at the Factory in Santa Cruz, California. We also suggest contacting your local Santa Cruz retailer to check for demo availability in your area.

Where can I find additional technical information for my bike?

Currently all technical info is located either on the bike archive or under tech support. Both can provide helpful information for puzzling with your bike, torque specs, and exploded diagrams.

Won't my BB be too high if I put 2.8" tires on my bike?

Thanks to the flip-chip on the link, you can adjust the bb height to account for the different tire diameters. You can achieve the same bb height with the plus configuration as you do with the standard one.
