Specifications

Upgrade your mountain biking experience with the ethirteen Sidekick Rear Hub - the ultimate choice for performance-driven riders seeking unmatched suspension efficiency and durability. Designed for 12 x 148mm thru-axle systems with a 6-bolt disc brake interface, this high-performance rear hub features a sleek black and sterling silver finish, complementing any full-suspension mountain bike setup.

Materials & Construction:

Constructed from highly CNC-machined, weight-optimized aluminum, the Sidekick hub offers exceptional strength and durability while minimizing weight (weighing only 423 grams). Its premium cartridge bearings ensure smooth, reliable operation under rigorous riding conditions. Compatible with SRAM XD cassette bodies and designed for E-bikes, this hub is built to withstand the demands of aggressive trail riding and long-distance adventures.

Performance & Engineering:

The standout feature of the Sidekick hub is its revolutionary anti-kickback drive mechanism with adjustable deadband, which filters pedal kickback and chain vibration-reducing rider fatigue and improving suspension performance. Its innovative freehub disengages when coasting, significantly decreasing drivetrain drag, resulting in a smoother, more efficient ride over rough terrain. The adjustable pawl-pusher allows tool-free tuning of deadband between 12 , 15 , and 18 , offering customizable traction and suspension behavior tailored to your riding style and terrain.

Components & Technology:

Equipped with a durable 60T ratchet ring paired with a unique pusher-driven pawl system, this hub ensures near-silent operation and minimized chain slap. The J-bend spoke interface facilitates easy wheel building and maintenance. Engineered for 6-bolt disc brake compatibility, the hub delivers consistent stopping power while maintaining optimum weight distribution. Plus, its fully serviceable and rebuildable design, proven on the World Cup circuit, guarantees long-term reliability and performance.

Style & Use Case:

Designed for enduro, trail, and all-mountain riders who demand the best, the ethirteen Sidekick hub combines sleek aesthetics with innovative engineering. Whether tackling technical descents or powering through long climbs, this hub provides enhanced traction, controlled acceleration, and a silent ride environment. Its distinctive black and silver finish makes it a stylish upgrade for any high-performance mountain bike build.

Innovative & Differentiating Features:

- Unique anti-kickback drive mechanism with adjustable deadband for improved suspension responsiveness
