THE DETAIL

Combine HyperBoost3-R with Black-lock and get a super-stiff tricky assembly.
The overall hub system is the world's lightest and employs bigger bearings than most competitors.
Freehub employs 2 corrosion-resistant stainless bearings (6803-2rs), hub shell rotates on a"heavy-duty"
(6903-2rs) corrosion-resistant stainless main bearing that can handle 250kg and low friction (6803-2rs) bearing on the disc side.
The "heavy-duty" 6903-2RS on the disc side is also available as an 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.
The 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 hub shell splines increase overall lifespan by over 35% and simplify 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.
