Santa Cruz Bronson – 650B Enduro Racer in Carbon and Aluminum

April 14,2013


Natural carbon Bronsons will be offered in a number of color graphic options and if you pop for the Enve carbon wheel option, you can get them matched to your bike.

Santa Cruz has been busy this season and secretive about its plans – the first of which is the Bronson 650B line. The six-inch-travel VPP design will be offered in both carbon and aluminum in a wide number of build kits (Shimano and SRAM) that range in price from $4150 to $10,419, so there is a Bronson suitable for both thousandaire and millionaire Enduro pilots alike. Most of the release is about the top-line Enve/SRAM XXI build, which is quite stunning. The new carbon frame is updated with all of the bits that were developed for the Talboy LTC – co-molded aluminum pivot bosses, and the simplified swingarm design. The lower rocker is still sturdy aluminum and all the main suspension bearings are adjustable.

Black Bronson

Billed as an enduro racing bike, the Bronson should put the mid-size 27.5″ wheels (650b) to the ultimate test.

Bronson Details:
• 27.5″ (650b) wheels
• 142 mm rear axle spacing.
• New molded rubber swingarm and downtube protectors.
• 2 x bottle cage mounts.
• Forged upper link.
• Forged aluminum lower link with angled grease ports: offset for chainguide clearance.
• Collet axle pivots: lock in place without pinch bolts.
• Angular contact bearings: all pivots.
• Direct mount rear derailleur hanger option: standard hanger comes as stock.
• Full carbon dropouts and disk mounts.
• Co-molded aluminum hardware on frame pivots: no bonding.
• Carbon ISCG-05 tabs.
• Routing for Reverb Stealth dropper post.
• 73mm threaded BB.

The Bronson

The aluminum-frame version is pretty sweet looking too. Geometry is adjusted for 27.5 inch wheels, so the 67-degree head angle is going to feel closer to 66 on the trail.

Bronsons will reportedly be the spearhead for the Syndicate’s push into the European enduro racing scene, where the Santa Cruz sponsored team plans to do some damage. Rumors have it that Santa Cruz, which has been cautious to enter new markets, has been testing the Bronson for an extended period, lending credibility to the notion that the mid size wheel is much more than a fad. If you remember, SC was reluctant to offer up a 29er, but when they did, it was an instant hit. We expect the Bronson to follow suit. Is there a 650B V-10 hiding in the new Santa Cruz factory? Syndicate riders say nay, but I am thinking, yeah.


Bronson. Aluminum.

Bronson frames follow much of the new design improvements ushered in by the Tallboy LTC – a simplified swingarm design, sturdy aluminum rocker links, and adjustable angular contact bearings in the suspension pivots, but there are some new tricks, like internal dropper post routing and a direct-mount front derailleur (SC originally espoused that a clamp-type was best for those who ran and single chainring). Santa Cruz hinted that the Bronson was only the first of two big releases this spring. Sea Otter may hold another gem. we’ll keep you posted.
