Santa Cruz Bronson Alloy S 27.5+ Mountain Bike 2020

The Santa Cruz Bronson Alloy S 27.5+ Mountain Bike is their do-it-all thriller. It doesn't have the most travel on the suspension but it is more than competent and will take everything in it's stride, from technical to flat out. The Bronson is the bike with the big character.

Santa Cruz set to work on the suspension, the patented Virtual Pivot Point, VPP provides flexibility to manipulate the shock rates, fine-tuning to the max. The aluminium frame has a balanced geometry that makes it agile over tracks or paths. The RockShox fork increases the precise handling ability with up to 160mm of travel to help absorb bumps.

Rolling on 27.5" wheels increase the agility of the Bronson and it can navigate technical sections with aplomb with the rider having responsive handling to pick a line. The DT Swiss hubs ensure smooth rotation whilst the Race Face AR rims provide a stiff and robust finish. The wheels are tubeless-ready, a quick setup will allow you to run the tyres at a lower pressure and reduce the potential for flats. Braking is reassuringly modulated and powerful, the hydraulic disc brakes will continue to offer this in all riding situations. The huge range of gear ratios come courtesy of the 12-speed drivetrain, the SRAM GX Eagle setup will make tackling any ascent not quite a breeze but will remove the excuses and still have something left for the descents. The shifting is reliable and consistent, SRAM's components are race-proven.

Using the RockShox Reverb Stealth dropper post you can adjust your saddle height when facing a technical section that may require a bit more hanging off the back of the saddle, and better still you can do it while you ride. The Bronson is all about confident fun.
