Epic bikes have an FSR suspension system that's completely locked out until bump forces are detected, but so sensitive it can "read" less than 1G of input. Then the shock responds instantly. Once activated, the Epic's FSR suspension is fully active and independent...and remains that way until the terrain becomes smooth, the inertia valve closes, and the shock is locked out again. It's that simple. And that effective.
FSR: The Next Generation
Specialized engineers began working with suspension guru Horst Leitner more than a decade ago to create the technological breakthrough that became the patented FSR four-bar linkage suspension system. Since that time, FSR has become the most successful system in bicycle suspension history...so much so that more than a dozen of our competitors now license it for use on their own bikes.
About the only disadvantage to FSR was that the system sometimes responded when you didn't want it to...specifically when pedaling out of the saddle on smooth surfaces.
Inside the Brain
How does the Epic work? Very well, thank you. But the secret's in the Brain. Brain technology consists of an inertia valve mounted inside a near-vertical cylinder near the Epic's rear axle. The inertia valve controls the shock's ability to compress; the result is a system that responds to terrain input (bumps and dips), but not to rider input (you, pedaling the bike) until the going gets bumpy.
