Key Benefits for Riders
Customizable Suspension for Optimal Performance

Paired with the RockShox Psylo Silver fork with Motion Control Damper, this bike absorbs rough terrain with ease, providing an excellent balance of control and comfort for both climbing and descending.
Precision Shifting and Reliable Braking
The Shimano Deore 12-speed drivetrain ensures precise shifting with smooth transitions, whether you're shifting up for a climb or down for a descent. For stopping power, the Shimano MT-420 4-piston brakes provide reliable and powerful braking performance, giving you confidence on any trail, especially in technical or steep sections.
Durable and Adjustable Components
The M5 alloy frame offers durability and lightweight performance, while the SWAT Door integration allows you to store tools and gear for convenience on long rides. The TranzX dropper post provides adjustable travel, giving you the flexibility to change your saddle height for steep descents or technical terrain, with easy remote control via the SLR LE lever.
Designed for Comfort and Control
Geometry adjustments on the Stumpjumper 15 Alloy give you the option to dial in the head tube angle and bottom bracket height, making it adaptable for different trail types. The 6000 series alloy handlebars offer a comfortable grip with a 6-degree upsweep and an 8-degree backsweep, ensuring a natural riding position. Combined with the Bridge saddle, this bike is built for long rides with a focus on rider comfort.
