Santa Cruz Bronson Alloy R1 27.5" Bike

Santa Cruz’s Bronson Alloy R1 27.5" Bike builds on the trail-blazing status of its predecessor, which redefined what a 150mm trail bike can do. This model has had its geometry evolved to meet the demands of today’s most aggressive riders. It now features a long top tube and slacker headtube for much-increased stability, plus shorter chainstays for amazing handling and excellent “whipability”!

SRAM NX 1X11 Drivetrain

The Bronson also benefits from Santa Cruz’s VPP® rear linkage arrangement. This drastically enhances the lateral stiffness and durability of the rear end and encourages an ultra-efficient climbing ability. Kitted out with Fox Rhythm 150mm forks, a RockShox Monarch RT and SRAM’s NX 1x11 drivetrain, the Bronson Alloy R1 is ready to help you own the trails.

Easy Assembly

When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

  • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer's boxes.
  • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer's boxes.
