Sidekick is the only hub that simultaneously eliminates pedal kickback, delivers near-zero freewheeling drag, and coasts near-silently — built for trail, all-mountain, enduro, and E-MTB riders at a price within reach of every rider.
The pusher-activated magnetic pawl mechanism fully decouples the drivetrain from the rear suspension during coasting, letting the rear end move freely through its travel without fighting chain tension. The result: better small-bump compliance, more traction on rough terrain, and a ride that feels effortlessly fast out of corners. BYB Telemetry testing shows up to 44% more time spent in the optimal 11–70% suspension travel range.
Tool-free deadband adjustment gives you three settings changeable trailside in seconds. At 9°, engagement is fast and direct — comparable to a conventional hub, ideal for climbing. Open it 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).

- Near-zero freewheeling drag — At least 55% less coasting drag than competing hubs in controlled tests

- Tool-free deadband adjustment — 9° / 13° / 18°; narrowest setting for quick climbing engagement, wider settings for maximum anti-kickback performance

- Driver compatibility — XD, HG, and Microspline; 148mm (Boost)
- Disc mount & spoke options — 6-bolt 28h configurations
