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 plus the all-new, aggressive geometry, is dialled 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 maximise stiffness and minimise 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 organised 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 (80mm size small).
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 pedalling 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.
