2021 Specialized Stumpjumper Pro Mountain Bike

2021 SPECIALIZED STUMPJUMPER PRO MOUNTAIN BIKE
The Specialized Stumpjumper Pro Mountain Bike is the culmination of thousands of lab and testing hours, designed to make for a premium trail experience. Visually similar, all-new. Retaining the striking asymmetric visuals of the previous generation, this new frame has been rebuilt from the ground up to run rings around other bikes in its travel bracket. An ultralight frame provides an incredible balance of stiffness to weight, and redesigned suspension kinematics offer improved performance all over the hill.

Simply put, the new Stumpjumper rips. Destroying pre perception is what the range does best, with this new chassis truly pushing the boundaries of what is possible on a mid-travel frame. Utilising a more progressive leverage curve, the 130mm of travel works smarter, not harder. As the shock moves through its stroke, progression increases slowly to ensure every millimetre of suspension is used to the advantage of the bike. A sharp ramp at the end prevents the bike bottoming out on heavy hits, encouraging rowdy riding and boosting confidence on technical terrain. Pedalling performance has also been improved to devour quad-burning climbs with ease.

Rider-First Engineered™ sizing allows you to pick a frame size that suits your riding, not your height. Short seat tube heights allow riders to size up or down depending on preference. Size up for stability or size down for a playful ride - the choice is yours. Revised SWAT™ storage sees more room available for tools, accessories and nutrition, while still retaining incredible frame strength.

The pro-level specification ensures this ride is race-ready right out the box. Top-spec FOX Factory suspension sees Kashima coated stanchions for ultra-low breakaway forces, with the latest GRIP2 fork damper offering critically acclaimed performance in a 140mm package. Made to match, the FOX Transfer dropper seatpost adds flow to your ride on undulating terrain. The SRAM XO1 groupset is lightweight and feature-rich, and 29" Roval Traverse Carbon rims have low rotational weight for lightning-quick acceleration. Aftermarket Deity components grace the cockpit, with their Copperhead stem and tacky knuckleduster grips being specced respectively.
