Stumpjumper 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 pure-bred cross-country machine is available in both carbon fiber and alloy frame options, plus the aggressive geometry is dialed for precise handling at race speed.
WHAT Designed for specifically for XC racing, the XCP fits 27.2mm seatpost diameters, features a carbon constructions, and has two ride positions, with a 35mm drop position.
WHY Optimized saddle height for XC racing is crucial for maximizing output to the pedals when climbing. However, lowering the saddle height with the XCP lowers a rider's center of gravity for improved handling and control when they need it most—descending technical trails.
HOW By integrating the proven Command Post IR technology into an XC race platform designed for bikes with a 27.2 mm seatpost diameter. The carbon construction saves weight for riders concerned with the added features of the component, while the ability to actuate and raise or lower the XCP on the fly gives riders the optimized positions for both climbing and descending with the ease of a handlebar-mounted lever.
WHAT The new lightweight and stiff M5 alloy frame has refined XC Race Geometry, vertically compliant shaped seatstays, PF30 BB, tapered head tube assembly.
WHY To offer best stiffness-to-weight ratio in its class without sacrificing vertical compliance. Results in high performance with a smooth, controlled ride. The refined XC Race Geometry features more aggressive angles to meet the demands of the sport's fastest riders.
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.
WHAT 90mm-travel Brain-modulated fork on mid to high-end models.
WHY The only shock that knows the difference between rider and trail induced bumps, the Brain thinks for you and delivers the smoothest, most efficient ride.
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 you stand to accelerate, the fork immediately stiffens up, eliminating "bob" motion. But, when taking a hit from a rock or a root, the fork is allowed to compress accordingly.
WHAT Ultralight FACT IS carbon frame with shaped seatstays, XC Race 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 SWAT standard on Stumpjumper Expert 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 SWAT items are strategically integrated into the frame at the water bottle and organized by location and weight for easy access.
