Designed and engineered for the demanding disciplines of 4X, Dirt Jump, and Dual Slalom, the 831 uses the FOX
32 mm platform, FLOAT® Air Spring technology, and FIT RLC damper. The 831's FIT RLC damper is specifically valved with firmer low- and high-speed compression damping to increase pedaling efficiency when sprinting out
of the start gate and absorbing large jump landings.
The FLOAT air spring has been designed to add more progression, to push back on the rider during high cornering loads, and help better control bottom-out.
The 831 was developed and tested during the 2009 season using the 2009 4X World Cup Champion Jared Graves, riders Cameron McCaul and Dan Atherton, and the 2009 Crankworx Dual Slalom champion Kyle Strait.
