Specialized Stumpjumper Alloy Flip-Chip
The Specialized 2021 Stumpjumper Alloy comes with a flip-chip to adjust the rear wheel location change how the bike rides. The Stumpjumper comes from Specialized in "low" position. This video adjust the flip-chip into the "high" position. The "high" position decreases the chain stay length by 4 mm (-4 mm), increases the bottom bracket height by 7 mm (+7 mm), and increases the head tube angle by 0.5 degrees (+0.5 degrees). For official information and the specific torque setting go to this website https://www.specialized.com/us/en/stu... and download the "2021 Stumpjumper Allow User Manual." This video is my experience and your's may differ. By no means is this a recommendation on how to setup you bike. Proceed at your own risk.
