When the trail demands a quick, efficient and agile weapon, the STUMPJUMPER hardtail answers the call. With numerous World and National Championships to its name, this purebred cross-country machine is available in both carbon fiber and alloy frame options, plus the all-new, aggressive geometry is dialed for precise handling at race speed.
WHAT Ultralight FACT IS carbon frame with shaped seatstays, Competitive XC geometry, and slim seatpost.
WHY The remarkably lightweight 29er frame weighs less—without sacrificing torsional stiffness or vertical compliance. Results in increased speed, comfort, and control over rough terrain.
HOW FACT IS construction lets us create complex carbon shapes that maximize stiffness and minimize weight and stress/ alignment issues. The geometry—featuring our tapered headtube and short chainstays—provides superior handling and snappy acceleration. The shaped seatstays and slimmer seatpost increase vertical compliance.
WHAT Fully integrated emergency repair kit, featuring storage, water bottle holder, air canister compatibility and multi-tool. Stage 3 Kit standard on Expert Stumpjumpers and up.
WHY Gives endurance riders the ability to solve any minor mechanical problem on the trail, and eliminates the need to wear a pack.
HOW The S.W.A.T. items are strategically integrated into the frame at the water bottle and organized by location and weight for easy access.
NEW CARBON WHEELSETS
WHAT All-new, lighter-weight Roval Control SL 29 wheelsets (S-Works) with Zero Bead Hook technology, and Roval Control Carbon 29 wheelset (Marathon and Expert).
WHY Zero Bead Hook technology creates a lightweight and impact resistant wheel. The lightweight wheels improve climbing performance and acceleration out of corners.
HOW Roval designed this lightweight carbon wheelset with a carbon rim that is stronger and stiffer than alloy, so the wheels remain in-true longer, and absorb impact better.
Zero Bead Hook simplifies the rim manufacturing process, resulting in a lighter-weight rim that with edges more resistant to sharp rocks and rough terrain.
CUSTOM ROCKSHOX SID BRAIN FORK
WHAT 90mm-travel Brain-modulated fork on mid to high-end models.
WHY Delivers the most efficient climbing and out-of-the-saddle acceleration, while retaining smooth, active suspension when taking hits.
HOW Brain technology (inside the fork) senses the difference between actual bumps and pedaling force, using an inertia valve and oil flow to regulate suspension. When a rider stands to accelerate, the fork immediately stiffens up, eliminating rider “bob.” But, when taking a hit from a rock or a root, the fork is allowed to compress accordingly.
M5 ALLOY FRAME
WHAT Light, stiff M5 alloy frame with shaped seatstays, PF30 BB, tapered head tube assembly, and Competitive XC geometry.
WHY To offer best stiffness-to-weight ratio in its class without sacrificing vertical compliance. Results in high performance with a smooth, controlled ride.
HOW M5 alloy frame is hydroformed to create the optimal shape for each tube’s function. The geometry—coupled with a tapered head tube assembly, PF30 BB and short chainstays—provides quick, responsive handling and acceleration. The sculpted seatstays have a flatter surface on top and bottom which increases vertical compliance for comfort but maintains torsionally rigidity.
WORLD CUP BUILDS
WHAT Optimized feather-weight drivetrain and tire choices to meet the needs of highly competitive XC racers.
WHY When every gram counts and races are decided by fractions of a second, the fastest and lightest equipment can make or break who crosses the line first.
HOW SRAM 1x11 shifting and Magura brakes deliver the lightest performance package on the market. Our Renegade tires are lightweight and roll effortlessly.
