Hydra is the culmination of over two years in development and countless hours of testing and refining.

With an incredible 690 points of engagement (that's just 0.52 degrees), the new Hydra drive system is the next level in hub technology.


Utilising a 115 tooth drivering and a phased six pawl engagement Industry Nine Hydra re-writes the rules for hub performance.



The Design

The design is a continually "phased" drive system that creates a procession of engagement points between the pawls and the drivering.

By utilising the inherent flex in the hub system, it allows positive second, third or even fourth pawl contact providing almost instant engagement that means solid power transfer from your legs to your pedals.

The new design also minimises stress through the system that results in longer lasting bearings and less drag 


Every Hydra Classic hub is manufactured from start to finish in Industy Nines own factory in the United States.

From design and development, engineering, manufacturing, and anodising right through to final assembly.
