Have a poke around the internet if you don't believe us, this wheelset is grabbing top marks in every review it gets close to. 

The Hydra Hubs

Every Classic mountain hub is made start to finish in Industry Nine's Asheville, NC machine shop. From turning and milling bar stock 7075-T6 aluminum for shells, axles and endcaps, wire EDM cutting A2 tool steel for pawls and driverings, to their own in-house anodization lab, every step of design, engineering, manufacturing and assembly is done on premises to exacting standards.

The culmination of innumerable miles on the bike and hours in the shop, the new Hydra hubs are the pinacle of engineering. An evolution from the already super impressive Torch drive system, Industry Nine's new Hydra drive is a project over two and a half years in the making. Featuring an insane 690 points of engagement, or .52° between each engagement, Industry Nine claim they have maximised the potential of the mechanical engagement system. A 115 tooth drive ring combines with 6 leaf-sprung pawls that engage individually at first, but when torque is applied (through pedalling) team up to create a solid and reliable feeling of instant engagement.

From the outset of the Hydra project, Industry Nine focused on improving bearing life and reducing drag in comparison to their previous efforts. Hydra tempers uncontrolled axle and bearing movements conventional designs can’t mechanically limit, thus improving bearing life and decreasing resistance. Hydra offers consistent, reliable engagement without overloaded bearings, axles or hub shells.

With performance taken care of, Industry Nine have also improved the serviceability of their hubs with the Hydra. The new hub design gave Industry Nine the opportunity to update their end caps as well. Industry Nine have updated the drive side end cap to hold a larger o-ring that is intended to be more durable and has a much lesser chance of being compromised during routine maintenance. 

Suitable for any discipline of riding, the Hydra hubs are lightweight, reliable, built to last and easily serviceable without the use of any proprietary tools.

Last - but by no means least - there's the noise! There's nothing quite like it! It's tunable with different viscosities of grease, but if it we're our money we'd turn it up to 11!
