Description
Specifications

Upgrade your mountain biking and eBike performance with the Industry Nine Hydra 2 Classic Rear Hub - the ultimate combination of durability, precision, and innovative engineering. Designed for trail, enduro, and downhill riding, this 12x148mm, 6-bolt, SRAM XD compatible hub offers unmatched engagement and reliability in the most demanding conditions.

Materials & Construction

Crafted from high-strength materials, the Hydra 2 features scalloped flanges that enhance overall hub shell strength while reducing weight for optimal performance. The hub shell is finished in a sleek black anodized coating, providing corrosion resistance and a refined aesthetic. The hub utilizes sealed cartridge bearings, specifically 6903 models, which deliver smooth rotation, exceptional longevity, and are designed to withstand rugged riding environments.

Performance & Engineering

Re-engineered from its predecessor with over 100,000 units in the field, the Hydra 2 boasts a 65% thicker axle, ensuring superior resistance against stresses encountered during aggressive riding and full-power eBike use. The enlarged pawl pockets (26% larger) evenly distribute force, preventing wear and deformation over time, while the full-contact radial lip seals and proximity dust shields keep grit, mud, and grime out, maintaining optimal lubrication and performance.

Components & Technology

The Hydra 2 features a revolutionary 6-pawl freehub body with an engagement angle of just .41 degrees, offering an incredible 870 points of engagement (P.O.E.). This results in immediate power transfer and telepathic responsiveness, ideal for technical trail sections. The refined drive ring and increased tooth counts on each pawl boost reliability and reduce drag, ensuring a smooth, silent ride. The enlarged 5.5mm pawl pockets improve force distribution and longevity, making this hub a reliable choice for seasoned riders and eBike users.

Style & Use Case

Built for aggressive trail riding, enduro racing, downhill descents, and high-powered eBike setups, the Hydra 2 hub combines sleek black aesthetics with robust performance features. It's compatible with 12mm thru-axles and 28-hole spoke configurations, offering versatile wheel-building options. Its 6-bolt disc brake interface ensures broad compatibility with top disc brake systems, providing confident stopping power in challenging terrains.

Innovative & Differentiating Features

- Advanced Engagement: 6-pawl design with a groundbreaking 870 P.O.E. for rapid response.

- Durability: Thicker axle, larger bearings, and larger pawl pockets prevent deformation and extend service life.

- Sealed Performance: Full-contact radial lip seals and dust shields keep out debris and retain lubrication.

- Lightweight yet Strong: Scalloped flange design reduces weight while increasing strength, ideal for aggressive riding styles.

- Designed for eBikes: Specifically engineered to handle the torque and power of full-power electric bicycles.
