Specialized Stumpjumper Expert Mountain Bike 2022
It is a hugely capable trail bike that can take on whatever is thrown at it, with 130mm of rear suspension from a FOX FLOAT DPS Performance Elite shock and a 140mm FOX FLOAT 34 Performance Elite fork to soak up the hits, provide excellent traction and increase confidence. The geometry is also very confidence-inspiring, with Rider-First Engineered™ design that allows sizing up or down depending on whether it is stability or nimbleness that is prioritised, and a flip-chip gives 1/2° of head angle adjustment for fine-tuning.
A 12-speed SRAM X01 / GX drivetrain adds fast, dependable shifting across the wide range cassette whilst the 4-piston SRAM G2 RSC hydraulic brakes won’t be found wanting on even the gnarliest trail. The 29” Roval wheelset makes good use of DT Swiss’ fantastic 370 Ratchet hubs, and the 30mm wide, tubeless-ready rims bring increased tyre stability and support when cornering hard. Specialized’s Butcher and Purgatory tyre pairing are a proven favourite of many riders, balancing grip, weight and durability to match the frame’s multi-faceted talents.
Tools can be stored in the SWAT compartment in the down tube, keeping the weight low down and out of harm’s way.
