Specialized Stumpjumper 15 Comp Alloy Description:
No more trade-offs, no more compromising, the Stumpjumper 15 Alloy is here and ready to "Rule All Trails". Short travel efficiency and control mixed with long travel downhill squish, from big hits to chunky descents, long climbs to smooth lines, the playful and predictable ride quality can not be matched. Genie suspension provides the best in air spring technology. Shimano's got your back with smooth shifting across a wide range of gears and plenty of stopping power to charge into corners at full speed. Uncertain of where the trail ahead leads, rest assured the Stumpjumper 15 knows the way, and it will be good.
