A revolution in MTB wheels, combining the suspension and performance benefits of Sidekick anti-kickback hubs with the control and comfort of engineered compliance from Grappler Flux rims.
Grappler Sidekick Flux Enduro and Downhill Wheels are a groundbreaking revolution in MTB wheels. Tested over two World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results. Sidekick hubs feature an adjustable deadband that eliminates pedal kickback, enhancing suspension performance and filtering drivetrain shock and vibration before it reaches the rider. Low-profile Grappler Flux rims set new standards in compliance, strength, weight, and performance. Together, these technological marvels offer increased comfort, enhanced speed and control, and a lively ride feel that puts wooden-feeling hoops to shame. Efficient and predictable suspension performance, added traction and tracking, reduced rider fatigue, and nearly silent hub operation create a more confident and immersive ride experience for both pros and enthusiasts.

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.
