FSR by Specialized Bicycle Best for Control and Comfort

FSR Traction Means Control

When you increase traction you increase control.  Since FSR suspension is totally independent of the chain and brake loads, it is "active" or able to freely compress and rebound over every kind of bump, gully, and ground cover. Since the tires are now able to maintain contact with the ground a greater percentage of the time, the obvious follows:  More tread on the ground more of the time translates into greater control.

FSR Active Suspension Means Comfort

Active suspension absorbs bump impacts, reducing the forces that make it to your body.  It takes energy for your body to deal with jolts and vibration.  As these repetitive impacts are reduced, you have greater endurance and less fatigue.

FSR Means Control, Efficiency, and Comfort

FSR separates the drive train and braking from the main pivot.  The patented approach provides a fully active and totally independent system.  The result is that  the rear suspension can compress and rebound without effecting other rider functions  (chain and brake forces).  The benefits are everything you could hope for.  You get increased control, efficiency and comfort with less fatigue.  100% of the torque you deliver to the chain moves the bike forward.  Nothing is lost to up and down motions.
