One Bike To Rule All Trails

Stumpjumper 15 is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. How about a heaping helping of personalization to make it perfect for the only rider who really matters—you?  Check, check, check.

BREAKTHROUGH CAPABILITY: GENIE Shock Technology combines a poppy, playful ride with a bottomless DH feel.

ULTIMATE CONTROL: Measurably better traction than “Bike of the Year” Stumpjumper EVO.

UNMATCHED PERSONALIZATION: Six-way geometry adjustment, mixed wheel or 29”, tunable spring curve, and more.

GENIE—The Magic Carpet Ride: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology that we invented grants every trail rider’s three wishes: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable “platform” for a playful feel.

I’ve tested every generation of Specialized’s full suspension Stumpjumper, and the latest version with the Genie shock tech is the best yet  - MBR

Jul 2, 2024 · Alan Muldoon

Specialized’s Stumpjumper Evo is without doubt, one of the best mountain bikes on the market. And I’m not just throwing that statement out there lightly… the Stumpy Evo has the test results to back it up. The carbon version took the top spot in our 2022 Trail Bike of the Year test, and more recently, the alloy Stumpy Evo won our Adjustable Trail Bike shootout. One of the most Decorated trail bikes ever made? You bet. And it’s not just MBR that sings it praises, the Stumpy Evo is universally regarded as the benchmark trail bike. So how do you improve upon such an accomplished ride? What you don’t do is throw the baby out with the bath water. So while Specialized has dropped the EVO tag, the funky side-arm frame layout, and a bit of travel with this latest version, the fundamental shape and attitude of the bike remains unchanged. And having spent four days on the new Stumpjumper 15 Pro Carbon I’m convinced it’s the best version yet, and better than the old Evo bike it replaces. And it’s the changes to the suspension layout and the new Genie shock technology that elevate the overall ride quality to new heights. If you want to read the headline changes and check out the models and prices, read our news story on the Specialized Stumpjumper 15. Specialized Stumpjumper 15 Pro Carbon Need to know 15th version of Stumpjumper replaces old Stumpjumper Evo Rear travel is 145mm, down from 150mm Fox Float shock with Genie dual-stage air spring tech for more adjustment Custom tuned 150mm Fox 36 Grip X2 fork with lighter damping Carbon frame and suspension layout mirror Levo SL Same geometry adjust features as old Stumpy Evo MX or full 29in wheels with dedicated shock links SRAM X0 T-Type AXS drivetrain New low-profile SWAT door, same storage capacity Improved seat post insertion on smaller sizes Six frame: sizes S1 to S6 Weight: 13.98kg (size S4 with SWAT) Four carbon models with Genie tech: S-Works, Pro, Expert and Comp One Ohlins model gets a 160mm fork and coil shock (EVO?) Frame and geometry Okay, so the most obvious change to the new Stumpy frame is that the distinctive side-arm, that ran parallel to the shock on the Stumpy Evo, is gone. And that shouldn’t come as a surprise, because one look at Specialized’s most recent trail bike, the Levo SL, says everything you need to know about the direction its design language is taking. In fact, the new Stumpy looks remarkably like the Levo SL, and the similarities extend to the suspension kinematics too. But I’m getting ahead of myself. Specialized claims that in bench tests, the new Stumpy frame sans-side-arm is every bit as stiff as the old design and isn’t any heavier. And, for a sub 14kg trail bike, the Stumpy 15 Pro Carbon that I rode certainly felt solid. So, I won’t be mourning the loss of the side-arm. Also if Specialized had kept it, you wouldn’t …Continue reading »
