Specialized Stumpjumper ST Alloy 29 2019 Mountain Bike Information

Season : 2019

Brand : Specialized

Code : 94718-73

All of you die-hard alloy fans can rejoice. Yes, the new Stumpjumper ST comes in an alloy version, and it may be the most radically designed alloy bike ever made.

When designing the frame with the stiffness targets being a main goal, Specialized have developed a radical new sidearm design. The front-end and rear-end are connected at three points, and the sidearm helps keep all these points super stiff and connected, all while taking about 100 grams out of the rear-end. More explicitly, this minimizes frame flex when the rear suspension is active. Another focal point of the tune was matching the suspension characteristics between wheel sizes, we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension.

With room for up to a 3.0" tire, You're also free to run whatever aftermarket rear shock you want, since we're using standard metric shocks.The SWAT box has also been revamped, making it sleeker, lighter, and with more volume. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain.

The build here is no-nonsense with a focus on dependable, high-performing parts, like Shimano SLX front and rear derailleurs, Tektro Gemini disc brakes, a RockShox Recon RL fork with 130mm of travel, a custom X-Fusion 02 Pro RL rear shock with 120mm of travel, and wide alloy wheels.
