Description

Manifest destiny.

It was only a matter of time before 27.5” wheels carved their niche into the mountain biking landscape. We’ve mused plenty on their ideal blend of characteristics, relative to their 26” and 29” siblings, but here, in the Santa Cruz Bronson Carbon Mountain Bike Frame, is arguably where this balance finds its finest manifestation, evidenced by the repeated success of the Bronson under the Santa Cruz Syndicate race team and countless other racers topping podiums in multiple disciplines. For 2015, the Bronson gets some new colors, but it's otherwise an identical machine to the 2014 version.

At the heart of the Bronson is a highly refined VPP suspension platform that's been optimized for mid-sized wheels. It's a suspension platform that's widely beloved among riders in-the-know for its blend of pedaling efficiency and trail-erasing smoothness. VPP employs two aluminum counter-rotating links to achieve this balance. But, you may be wondering how it works? Well, the upper-link provides most of the rotation as the bike compresses into the sag point. This yields a vertical wheel path, which you'll notice in the form of a firm feel during acceleration. As the bike compresses deeper into the suspension, the lower-link activates, moving the axle path rearward. The rearward axle path enables the rear wheel to travel out of the way of impacts. So, the ride remains smooth, not jarring. You'll also find the same collet-style pivot hardware that's become standard for Santa Cruz's suspension bikes. This means that your pivots stay tight and are easily serviceable at home if ever necessary.

Santa Cruz's industry-leading carbon fiber construction is on display here, as well. Both the front and rear triangles are constructed as a whole, rather than bonding them together from sub-assemblies. Not only does this save weight, but it also means that the Bronson is as strong as possible. This is because the fibers remain uninterrupted by seams. In fact, if you were to cut the Bronson in half, you'd find that the inside of the tubes have the same perfectly smooth finish as the outside. This is a result of a construction technique that maximizes the compaction of the layers. The benefit is that it's lighter, because any excess epoxy is squeezed from the frame prior to curing. Accordingly, Santa Cruz finds that this provides the ideal degree of compaction, further enhancing frame strength.

The rear shock is FOX's FLOAT CTD unit features the ultra-durable Kashima coating. While the distinctive gold color is eye-catching, the Kashima coating's true benefit is that it's both harder and smoother than standard slider coatings. This equates to a longer wear life, as well as smoother suspension action. FOX's CTD adjustment scheme makes it easy to find your perfect setting, whether you change settings dozens of times a ride, or just set it and forget it. With a nearly locked-out feel, Climb mode provides the most damping. However, it still provides a bit of cushion for unexpected hard hits. Meanwhile, click the damper into the Trail mode, and there's ample low-speed compression in order to keep the bike riding high in the travel, great for just cruising along in most conditions. Lastly, Descend mode provides the lightest compression damping for a plush ride, ideal when you want to let 'er rip.

The Bronson utilizes a 44/56mm headset for compatibility with tapered forks. The rear dropouts accept a 142x12mm thru-axle rear hub, which keeps the frame stiff under power. The 73mm English threaded bottom bracket shell ensures a creak-free crankset and easy service. The frame requires a 30.9mm seatpost and a 34.9 front derailleur, and it's only compatible with 27.5-inch (650b) wheels.

The 2015 Santa Cruz Bronson Carbon Mountain Bike Frame is available in four sizes from Small to X-Large and in the colors Dark Green/lime green and Satin Black/magenta.

Fun and Fast!

  • Gender: Male
  • Familiarity: I've used it several times

I have had the opportunity of riding this bike several times and love it. For a long travel bike it is extremely efficient on the trail, climbs well and rips downhill. Probably its best attribute is its balanced feel on the trail-from front to back and never noticed the suspension bottoming out. The suspension has a very controlled feeling and makes the ride quality buttery smooth. Whether you are racing or joy riding its definitely a bike that will leave a smile on your face and i highly recommend it.
