We blazed the trail in active and independent suspension, and have been refining it ever since. FSR technology delivers more comfort, control and efficiency than any other suspension design, by effectively isolating chain and brake loads. Through our 20-year progression of FSR we’ve been able to tune the ride to match the experience. The result: FSR technology is used to capture both Cross-Country and Downhill World Championships.
MAXIMUM TRACTION MEANS GREATER CONTROL > The FSR design is independent of chain and brake forces, therefore it's free to compress and rebound over terrain features whether you're pedalling or not; allowing the tyres to maintain contact with the ground a greater percentage of the time.
SMOOTHING TERRAIN TO MINIMISE IMPACTS & REDUCE RIDER FATIGUE > Active suspension is free to absorb trail-induced forces so the rider’s body doesn’t have to.
MAXIMISING EACH ROTATION OF THE CRANKS > The FSR drivetrain is independent of the suspension, so pedal stroke is not affected. Chain torque won’t engage the suspension, so as a rider puts effort into the pedals the bike will propel forward, not up and down.
It’s fast. It’s easy. It’s correct—every time. Think suspension set up is confusing? Think again. The groundbreaking AUTOSAG feature is exclusive to Specialized FSR models, and allows you to set up your suspension with only the push of a button.
The Czar of FSR: Jason Chamberlain
“Specialized has been using FSR suspension for over 20 years and I’ve personally been working with it for the last 15 years. By combining my experience with the decades of combined in-house engineering experience from our team, each year our understanding of the interaction between rider and machine advances. If you look at our original patent, it’s clear the understanding of mountain bike suspension was in its infancy. Today, we can design FSR to meet the needs of everything from cross-country to downhill terrain. It’s pretty cool to look back in history and see all of the World Championships FSR has won in basically all disciplines, cross-country, downhill, and 4-Cross."
