How Sidekick Improves Suspension

The adjustable deadband filters chain tension before it reaches the pedals, allowing the rear suspension to move freely without resistance from pedal kickback. This results in:

• Better small‑bump sensitivity


• More consistent suspension performance


• Improved traction and cornering stability


• Reduced rider fatigue on long descents
