Kinematic
The anti-squat setting achieves a sag value of over 100% to ensure high pedaling efficiency. This ensures that the rear triangle stiffens slightly when pedaling uphill, thus minimizing bouncing.
With an average anti-rise of 68% across the entire travel, it delivers a balanced braking experience suitable for downhill riding. The suspension remains active and compensates well for uneven terrain. Yet it's tuned so that you don't feel like you're about to roll over when braking on steep terrain.
The frame's progression is approximately 15% to cover the frame's wide range of uses. For sporty riders who desire more progression, the shock absorbers can be adjusted as desired.
Note: The Rationalist is designed for air suspension and can only be used with steel springs to a limited extent.
