INDUSTRY NINE Hub Set MTB Hydra Classic Center Lock BOOST | Freehub SRAM XD

INDUSTRY NINE hub set MTB Hydra Classic Center Lock BOOST | Freewheel SRAM XD

The Industry Nine Hydra Classic hubs are a real gem on every bike. Developed and produced in Asheville / North Carolina, they set themselves apart from the competition with many small technical refinements. With their externally sealed bearing and stable axle , they are optimally protected against environmental influences and also ideally equipped for downhill use. Beveled spoke flanges help to reduce the forces on the sensitive spoke heads and thus prevent spoke breaks.
However, the pawl freewheel on the rear hub is revolutionary. It consists of a drive ring with 115 teeth and 6 staggered pawls. These are designed so that as soon as one of them has a frictional connection, the others can also absorb torque shortly thereafter. This means that a single handle can only carry the power for a very short time. The big plus of this system is an extremely short free travel of 0.52 °, which brings clear advantages in technical passages or when accelerating hard. In addition, the fine grid leads to a unique background noise on the impeller.
The maintenance effort is also relatively low. You can disassemble and clean the hub without tools.
