SRAM Transmission: According to its DNA, our Stumpy EVO features a mullet setup with a 29-inch front wheel and a 27.5-inch rear wheel. The advantages of a larger front wheel with more grip and better rollover characteristics, combined with a smaller, more agile rear wheel, perfectly suit a playful riding style. The Stumpjumper EVO feels at home in the bike park and rides freely when you let go of the brakes on the trail. Even the longest suspension travel is useless without the right tune of the shock and the correct kinematics. That's why the design of the new Stumpjumper EVO prioritizes the performance of the kinematics. With insights from the suspension design of the Enduro and over 1,000 hours of development work on the trail and in the suspension lab, we have significantly improved climbing pedal efficiency while creating a powerful, efficient, and lively bike that every rider longs for. Additionally, we have increased the anti-squat value, allowing the suspension to better resist bobbing. Square obstacles are easily absorbed, resulting in less speed loss. With this bike, you can shred in any style. The geometry of the Stumpjumper EVO with S-Sizing is our most progressive geo to date. Long, low, slack, a fork with minimal offset, a steeper seat tube angle – these are the prerequisites for modern mountain biking. However, different riders have different requirements for their bike, which is why the geometry of the Stumpjumper EVO can be individually adjusted to your needs with six different settings. For example, the bottom bracket height can be raised or lowered by 10 mm, and the head tube angle can be changed by up to two degrees. All of this can be adjusted independently. Rider-First Engineered™ ensures that the bike's characteristics remain nearly the same across all frame sizes. Incredible handling and flawless performance are independent of frame or body size. Whether you're an S1 rider who loves to jump over everything or a downhill-hungry giant on an S6 – you both share the same riding experience: cornering like on rails and balanced stiffness front and rear at a shockingly low weight. When we introduced the SWAT™ box on the Stumpjumper in 2016, we freed up storage space in your frame for all the essential items you need when you shout out loud on the trail: “Oh sh*t!” A pump, spare tube, and mini tool fit easily and make straps on the frame unnecessary.
