Sidekick is the only hub that simultaneously eliminates pedal kickback, delivers near-zero freewheeling drag, and runs near-silently when coasting. Built for trail, all-mountain, enduro, and E-MTB riders, the Sidekick Rear MTB Hub unlocks the complete performance hub advantage at a price within reach of every rider.

The pusher-activated magnetic pawl mechanism fully decouples the drivetrain from the rear suspension during coasting. The result is a rear end that moves freely through its travel without fighting chain tension: better small-bump compliance, more traction on rough terrain, and a ride that feels effortlessly fast off corners. BYB Telemetry testing shows up to 44% more time spent in the optimal 11–70% suspension travel range.

The tool-free adjustable deadband gives you three distinct settings changeable trailside in seconds. At 9°, engagement is fast and direct, comparable to a conventional hub, ideal when climbing is the priority. Open it up to 13° or 18° for maximum anti-kickback and suspension performance on descents. The 17mm 7075 alloy axle delivers 50% more stiffness than the previous generation, at 300g (Boost 148mm) or 310g (157mm DH, Superboost).

• Eliminate pedal kickback full drivetrain isolation during coasting; suspension works as designed
• Near-zero freewheeling drag at least 55% less coasting drag than competing hubs in controlled tests
