Reign 29 SX Mountain Bike

Pick your line and let it rip. From chunky alpine terrain to warp-speed park runs, this hard-charging 29er feasts on rugged terrain, giving you the confidence to charge harder. 
Race-bred suspension
Maestro rear suspension and a 170mm fork developed and tested in Enduro World Series races. The trunnion mount rear shock has a longer stroke and smoother feel, and an Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight.
Progressive enduro geometry
A strong and durable ALUUX SL aluminum frameset helps you ride aggressive descents and rail corners with confidence. Enduro-optimized head and seattube angles, plus a 170mm fork with 44mm offset, produce confident front-end handling.
29er confidence and control
Larger 29-inch diameter wheels roll over rugged enduro terrain with improved balance and stability, giving you the momentum to crank up tough climbs and the confidence to fly on fast, technical descents.

Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
