Specialized Men's Stumpjumper ST Expert 29

Experience the thrill of the trail with the Stumpjumper ST Expert 29, designed for the discerning gentleman who loves to climb and shred with equal delight. This trail-conquering bike from Specialized boasts an exceptional combination of precise handling, optimised suspension kinematics, and a dismissal of proprietary components.

The Stumpjumper ST Expert 29 offers a steeper geometry, less travel (130mm front/120mm rear) and 29" wheels, comprehensively crafting it as a truly versatile trail bike.

The design goal was clear - create the ultimate trail bike that feels almost telepathic in response. By employing a mountain-specific stiffness test, we managed to create a frame that offers the perfect blend of stability and responsiveness. The result was a trail frame that stands as one of the lightest on the market.

The radical new sidearm design connects the front-end and rear-end at three points, enhancing stiffness while removing approximately 100 grams from the rear-end. This reduces frame flex when the rear suspension is active, dramatically increasing stability and control.

The new Stumpjumper features a custom Rx Trail Tune on both the fork and rear shock. The tune matches the suspension characteristics between wheel sizes, ensuring perfectly linear suspension, regardless of your preferred wheel size.

Practical conveniences have not been overlooked either. The Stumpjumper ST Expert 29 offers a revamped SWAT box for enhanced storage, and space for up to a 3.0" tyre. It also supports any aftermarket rear shock you wish to use. A Flip Chip allows you to fine-tune your ride according to your style, offering adjustments to the bottom bracket and head tube. Cable routing is easier than ever thanks to full tubes found throughout the carbon frame.

The build is impressive, featuring a full SRAM GX1 Eagle drivetrain, SRAM Guide R disc brakes, RockShox Pike RC fork and a Deluxe RT3 rear shock (130/120mm of travel respectively). Roval Traverse Carbon 29 wheels complement this sturdy and performance-oriented setup.

Unlock the mystery of the trail with the Stumpjumper ST Expert 29 - where stability, control, and ruggedness meet in perfect harmony.
