Santa Cruz Bronson Alloy R 27.5" Mountain Bike 2021
The Santa Cruz Bronson Alloy R 27.5" Mountain Bike is the livewire in the range, designed to get the adrenaline flowing, whether you're riding flat out, hitting the trails hard or going big on the more technical stuff. It has an aluminium frame complemented with 27.5" wheels for good rolling but agile handling at the same time. As you'd expect on a bike with the thrill in its veins, it has plenty of suspension included. Upfront you get a RockShox Yari RC offering up to 160mm of travel, and to assist this bump smoother, at the rear is a RockShox Super Deluxe Select with up to 150mm of travel. This shock uses the new Maxima Plush Fluid, created to reduce friction and to keep matters running smoothly and noiselessly.
The drivetrain is all SRAM - NX Eagle 12-speed, with SRAM also in charge of the braking, using SRAM Guide T hydraulic disc brakes with Avid Centerline 180mm rotors on both the front and rear. The Bronson isn't afraid to tackle to rough stuff and the R 27.5 is fully equipped to do the job.
