Santa Cruz Bronson Alloy Mountain Bike Frame 2021

Ready for sinuous singletrack, bruising downhill trails and high adrenalin jump lines, the Santa Cruz Bronson Alloy Mountain Bike Frame is versatility personified. Balancing the traits of agility and composure with aplomb this all-alloy chassis possesses a raw character that will ignite enthusiasm within any rider of any ability. The frame utilises high-grade alloy tubing and merges them via clean welds to result in a responsive, resilient and aesthetically pleasing chassis. The main triangle is joined in tandem by the rear, one-piece swingarm and they are joined via a VPP lower-link suspension configuration and RockShox dampener. This alliance promotes a composed shock rate, consistent mid-stroke support, and precise wheel tracking to result in a ride oozing responsiveness, pedalling efficiency and multi-ground traction. The already accomplished ride characteristics are then adjustable via the Flip Chip that nestles within the rear linkage. This alters the shock rate, bottom bracket height and bottom-out resistance in view of the riding complexity ahead to afford a completely personalised experience.

Scope of use of this already multitalented configuration is furthered still by compatibility with 27.5+ or 27.5” wheelsets and their matching gamut of tyre widths. Use 27.5" wheels with 2.4” tyres for more trail accuracy or 27.5+ wheels with up to 2.8” tyres for maximum grip and comfort. Bottle cage mounts within the mainframe triangle, a downtube protector, a chainstay guard and refined cable routing then complete what is a comprehensive trail steed.
