Description
Specifications

Experience unparalleled durability and precision with the Industry Nine Hydra 2 Classic Rear Hub - the ultimate choice for trail, enduro, downhill, and e-mountain bike riders demanding professional-grade performance. Crafted with innovative materials and engineering advancements, this 12x148mm boost-compatible hub combines enhanced strength, smoothness, and reliability to elevate your ride.

Premium Materials & Engineering Excellence

Built with a robust bronze finish and a reinforced, 65% thicker axle, the Hydra 2 leverages aerospace-grade 6903 sealed bearings and full-contact radial lip seals with proximity dust shields to ensure long-lasting smooth rotation and superior dirt resistance. Scalloped flanges on the J-bend hub shell optimize strength while reducing weight, delivering a lightweight yet durable build designed to withstand the rigors of aggressive riding and full-power e-bikes.

Advanced Components & Cutting-Edge Technology

The Hydra 2 features a groundbreaking 6-pawl freehub body with an 870 P.O.E. engagement ratio, engaging every 0.41 degrees for instant power transfer and precise control. Refined drive ring and increased pawl tooth counts enhance reliability and engagement efficiency, while larger pawl pockets-26% better force distribution-prevent deformation over time. The larger 5.5mm pawl pockets ensure consistent engagement and longevity, even under demanding riding conditions.

Designed for Performance & Versatility

Ideal for trail, enduro, downhill, and e-bike applications, this rear hub supports SRAM XD cassette bodies and 6-bolt disc brake compatibility, making it suitable for a wide range of modern mountain bikes. The 32-spoke hole configuration (32H) provides optimal spoke strength and stiffness, ensuring a responsive and confident ride. Its bronze finish not only offers an eye-catching aesthetic but also adds corrosion resistance for extended durability.
