Combine HyperBoost3-R with Black-lock and get a super-stiff tricky assembly.

The overall hub system is the world lightest and employs bigger bearings than most competitors.
Freehub employs 2 corrosion resistant stainless bearings (6803-2rs), hubshell rotates on a"heavy duty"
(6903-2rs) corrosion resistant stainless main bearing that can handle 250kg and a low friction (6803-2rs) bearing on disc side.
The "heavy duty" 6903-2RS at disc side is also available as option.

Bigger bearings are mounted onto a bigger 17mm diameter axle, multi-shaped and individually lapped to micro tolerances.
This creates a stiffer assembly that significantly increases bearing durability and hub stiffness.

Micro-tuner ensures a very precise bearing setting: minimum bearing friction with highest bearing durability and no play at the rim.

Additional external Soft-Touch O-ring seals keep dust and moisture away from the 2RS bearing seals promoting bearing longevity.

Third generation of Extralite's front engagement system increases the gap with the competition.
20% lighter floating-ring enhances engagement quickness and also reduces noise and drag.
Newly developed hubshell splines increase overall lifespan over 35% and simplifies maintenance.

Specifically designed long-life polyurethane Lip seal protects the freewheel mechanism from the elements..

Straight pull spokes increase wheel stiffness, reduce lateral flex and increase reactivity under torque transmission.

All this offers a sensible weight reduction and is well compatible with Berd spokes too!
