• A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper’s butted aluminum frame features hydroformed top and downtubes in order to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing and dropper-post compatibility.
• With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, we’ve paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper to fit every rider and the assurance that every Rockhopper is rolling on the best-handling wheel for its frame size.
• Bringing our Rx Tune to Rockhopper for the very first time, the lockout-equipped SR Suntour XCM with custom Multi-Circuit damping brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame or wheel size.
• Beautifully beastly, SRAM Level hydraulic disc brakes pack a mean bite but deliver their power with a refined, intuitive feel to make for a package that punches way above its pay grade.
• Keep things simple with a durable 1x MicroSHIFT drivetrain that offers plenty of range along with a clutch-equipped rear derailleur that keeps your ride quite—and your chain on.
• Pair dead-reliable hubs from Formula with our 25-millimeter internal diameter, hookless Stout rims for a wheelset hat-trick: strong, light and durable.

You started planning weekends around rides, rearranged the garage to fit more gear, and have singletrack dreams. It’s official: you’re a mountain biker, and you need a bike that’s as ready to rip as you. That’s the Rockhopper Expert 1X, our most capable Rockhopper yet.

STATE OF ALUMINUM ART

We gave the A1 SL Aluminum frame on the Rockhopper Expert 1X a lighter, tighter look with tube shapes that are optimized for the lowest weight while preserving its legendary comfort. With clean lines and internal cable routing, turns out it looks as sweet as it rides.

READY TO GET ROWDY

Stable and agile might seem contradictory, but the Sport XC 29 Geometry on the Rockhopper Comp 1X accomplishes both goals, with nimble, responsive handling for tight trails and superior stability when going fast, plus a rider position that’s comfortable for long rides.

Shimano’s reliable MT200 hydraulic disc brakes keep you under control with less effort at the lever.

10-speed Shimano Deore drivetrain offers precise shifts and long-lasting quality.

Wide 2.3-inch Ground Control Sport front and Fast Trak rear tires provide optimal traction and efficiency.

• THE TRAIL BENCHMARK — When we set out to design the all-new Stumpjumper, we pursued some hefty goals. It had to excel on any kind of trail, for every style of rider. To achieve that, we went after serious weight reduction without sacrificing durability, a stiff, responsive chassis that still rides light and lively, geometry that improves everyone’s riding, and the best suspension kinematics we know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper.
• THE SWEETEST 130MM OF TRAVEL YOU’LL EVER RIDE — We massaged the kinematics of the Stumpjumper suspension to bring out the very best all-round performance possible in a 130mm package. Countless hours of suspension lab development and field testing created a refined mid-travel ripper that eats big terrain like a gravity fed beast, handles like a dream everywhere, and climbs like it has a motor.
• PROGRESSIVE GEOMETRY — The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. It’s long, low and slack, with a short offset fork and a steeper seat tube angle. These numbers combine to make your ride more stable, more carvealicious, more comfortable climbing, more better everywhere. With FlipChip adjustability you’re able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose.
• RIDER-FIRST ENGINEERED™ — Rider-First Engineered™ frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance, regardless of frame or rider size. Whether you’re a jump-happy grom riding an S1, or a DH-fiend giant in need of the lengthy S6, you’ll experience the same ride traits – rail-sharp cornering and balanced front and rear stiffness – at the lightest-possible weight, And by light, we mean real light: 2,250 grams (S-Works, S-3 size, with rear shock).
