Specialized Stumpjumper 15 EVO Expert Di2 Complete Mountain Bike 2026

Mountain bikes are built for tackling rough terrain with frames made of durable materials like aluminum or carbon fiber, ensuring stability and maneuverability. They feature suspension to absorb impacts from rocks, roots, and drops, providing a smoother ride.

Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike.

Engineered to tackle the most challenging terrain with enhanced comfort and control. Unlike hardtail bikes, full suspension bikes feature both front and rear suspension systems that allow the wheels to move independently from the frame.

Carbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.

The Fox 36 is the undisputed all-mountain champion. Lighter, stronger, faster — the 36 continues to dominate the all-mountain category.

Performance Elite forks retain the same adjustments, features, dampers, weight, and 7000 series aluminum upper tubes as Factory Series, but have black anodized stanchions instead of Genuine Kashima Coat.

This fork features the GRIP X2 damper for maximum adjustability: high- and low-speed compression adjustment plus high- and low-speed rebound adjustment.

From aggressive trail to enduro, the advanced damping, fade free performance and class-leading durability of Float X makes it the versatile and lightweight choice for All-Mountain riders earning their descents.

Performance Elite shocks have all the same internals as Fox Factory models, just without the Kashima coating. Simply put, this is a highly tuneable and smooth shock made for aggressive trail riding.
