Hydra2 - MTN - 32 hole - RR Hub - Center Lock - Black - 12x148 - HG

Completely re-engineered using insights gleaned from more than 100,000 original Hydra hubs in the field, Hydra2 features a newly designed 65% thicker axle, larger 6903 bearings with new labyrinth seals, and enlarged pawl pockets that ensure bombproof durability under the most demanding conditions.

If that wasn’t enough, a refined drive ring and an extra tooth on each pawl enable Hydra2 to deliver lightning-fast 0.41° engagement with less coasting drag — making this engineering marvel Industry Nine's most advanced hub ever.
