M4 Manipulated Alloy
Every Stumpjumper frame is fabricated from M4. This proprietary material alloys aluminum with silicon, copper, magnesium and vanadium. The mix gives M4 outstanding strength characteristics (29% greater than 6061 aluminum), but the real benefit to M4 is its 'formability', which allows Specialized to optimize every tube shape and diameter.
Optimized Radius Engineering (O.R.E.)
The unique shape of the down tube and top tube on every Stumpjumper plays a major role in the bike's strength, light weight, and performance. By manipulating the shapes of these tubes, the gusset is eliminated, thus increasing strength (due to less welding) while decreasing weight (since less material is required.)
Because its fully active and independent, the suspension works perfectly under all conditions, and across all types of terrain, regardless of whether youre braking, pedaling, or coasting. Further still, each frame component and the pivots that connect them are designed to withstand the roughest terrain with confidence.
Specialized's TransForm monocoque technology begins with two halves of an optimized shape. Both frame halves are formed in precision dies and hydraulic presses, then welded together and heat-treated, and finally TransFormed into the perfect chassis. There are three primary benefits from the TransForm process:
The Stumpjumper FSR features a large air volume Fox rear shock for a more linear compression, and better trail performance. Fox ProPedal filters out pedal-enduced shock movement to enhance climbing efficiency.
