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 that ensure bombproof durability under the most demanding conditions.

• Designed specifically for trail, enduro, and downhill riders with the strength to handle full-power ebikes
• Scalloped flanges on Hydra2 j-bend hubs increase overall strength, and remove excess material for a lighter, stronger hubshell
• Revised axle design is 65% thicker with an improved stress washer design
• Full-contact radial lip seals paired with proximity dust shields keep grit and grime out, and lubrication in
• Durable 6903 bearings are used throughout for smooth, long-lasting performance
