Sidekick Hubs
What is Sidekick?
The Sidekick Hub by e*thirteen is a revolutionary rear mountain bike hub designed to enhance suspension performance by eliminating pedal kickback and filtering chain vibration.
How does Sidekick Work?
A proprietary freehub mechanism disengages the drivetrain from the rear wheel when coasting, and an adjustable engagement deadband filters kickback and chain vibration before it reaches the pedals, isolating all pedal feedback from the suspension.
What is Pedal Kickback?
Pedal kickback occurs when suspension movement applies tension to the chain, causing unwanted pedal movement and compromising suspension performance.
