HyperHubs Tips Page


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!
