Be honest, how demanding are the trails you ride really? If you don't live in Whistler or Finale Ligure and like to go on longer rides, then the Specialized S-Works Stumpjumper EVO is probably the right bike for you.

The storied Specialized Stumpjumper EVO—arguably the most famous mountain bike model in the history of our sport—is back for 2021, and the newest incarnation feels more refined and adjustable than ever before. With a headtube angle that’s adjustable from 65.5 degrees all the way down to 63 degrees, and a bottom bracket with height adjustability from 32 millimeters of drop to a ground-hugging 39 millimeters of drop, the new Stumpjumper EVO Expert we tested comes with multiple geometry options that can radically change its personality on a wide variety of terrain. The 2021 Stumpjumper EVO certainly has retained some of the climbing characteristics of its previous iteration. Specifically, it’s a bike that is far better to climb in the seated position than hammering out of the saddle—a trait attributed to the FSR suspension platform, which gives impressive traction through chunky terrain while climbing in the seated position. While climbing in the seated position, my weight felt balanced between the front and rear wheels, allowing me to stay comfortable and in control on even the steepest of climbs. I found the lowest bottom-bracket setting to be the best for climbing, as it extends the chainstay dimensions, adding to its overall stability. When it came to dialing in the compression on the super-active Fox Float DPX2 Performance Elite shock, I preferred switching it into the middle setting on the climb switch to slightly stiffen the pedaling platform.
