- The Stumpjumper excels on any kind of trail, and works for every style of rider, thanks to a 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
- The sweetest 130mm of travel you'll ever ride — Specialized 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, and more comfortable on climbs. 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™ frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance, regardless of frame or rider size. Rail-sharp cornering and balanced front and rear stiffness – at the lightest possible weight

Choosing your mountain bike
When it comes to choosing your mountain bike, it's a good idea to choose a model that suits your niche. A trail mountain bike makes a great choice for most first-time MTB buyers, offering a fantastic blend of speed, agility and all the singletrack ability of an enduro mountain bike. It's arguably the most versatile type of MTB out there.
With such a rich variety of models on the market, it's important to get to know a few. We've listed a few of our top picks below.
Cross country MTBs
Also known as an XC, cross country mountain bikes deliver the most exhilarating ride. Lightweight frames and top-spec components let you breeze through the most brutal uphill efforts and flow through technical descents. If you're thinking of competing, you can find flat-out acceleration with an XC mountain bike.
Enduro mountain bikes
Enduro mountain bikes strike a balance between versatile trail and downhill mountain bikes, built for all-out descents and featherweight climbing. Choose from aluminium or carbon fibre frames and enduro hardtail or full suspension mountain bike options to find an enduro bike that suits you, even on the trickiest ground.
Electric mountain bikes
When the going gets tough, you can push back harder. With an electric mountain bike, you'll get an extra boost from a powerful motor tucked away within the frame. These mountain bikes make it possible to explore the steepest trails and the most rugged bridleways with ease. At the push of a button, you can breeze through every new route.
