HyperBoost R+ 162g
World cup proven by some of the fastest athletes of the planet
Durable, precise and incredibly light: no shortcuts to reduce weight
The overall hub system is the world lighest but employs bigger bearings than most competitors:
freehub mounts 2 corrosion resistant stainless bearings (6803-2rs), hubshell rotates on 2 "heavy duty"
corrosion resistant stainless bearings (6903-2rs) that can handle 250kg each in the worst static condition
Bigger bearings are mounted onto axles of a bigger diameter. This creates a stiffer assembly that significantly increases bearing durability
Our MTB hubs feature also additional external seals to keep moisture and dust far from the 2RS bearing seals
Oversized 17mm axle is multi-shaped and individually lapped to micro tolerances
The new 60 P.O.E. freehub/floating ring mechanism has been released after 3 years of internal testing and 2 years of Open-Program tests
It further enhances engagement quickness, increases overall lifespan and simplifies maintenance
Specifically designed long-life polyurethane lip seal protects the freewheel mechanism
Micro-tuner ensures a very precise hub bearing setting, low bearing friction, higher bearing durability and no play at the rim
This external bearing preload device is very easy to set and integrates also an additional external Soft-Touch o-ring seal
Straight pull spokes increase wheel stiffness, reducing lateral flex and increasing reactivity of torque transmission
All this with a weight reduction too!

Wheel building instructions for
HyperFront - HyperLefty - HyperLefty2 - HyperBoost F
HyperRear - HyperRear2 - HyperCamber - HyperBoost R
Here you find all the necessary instructions to build up your dream wheels with pre-calculated spoke lengths.
Follow instruction step by step:
1) Measure your "spoke-end diameter"
2) Find your front spoke length on table A & B
3) Find your rear spoke length on table C or D
4) See specific notes about spoke and rim types
5) Follow correct lacing patterns
Rim offset:
2-3mm of rim offset influences the spoke length for an average 0.3mm only.
You may neglect it or eventually use that tiny amount just for rounding lengths to the available spoke size.
Maximum spoke tension:
Refer to manuals
Warning: spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.

"Spoke-End Diameter"
Rim manufacturers offer ERD figures however we warmly recommend to precisely measure the rim+nipple combination.
A truly correct spoke calculation requires exact "spoke-end diameter" and rim drilling (not ERD).
Spoke-End Diameter depends on your rim internal diameter and nipple type too.

IMPORTANT NOTE: on the Right flange Berd spokes should be always mounted without "Tangential Straightpull Inserts", that's due for bearing fitting clearance.

Important Notes
Rims: We consider rims with 2-4mm of offset.
In case of symmetric rims you may add 1mm to front-right and rear-left sides.
Steel Spokes: Flanges accept standard spoke heads however we recommend to use only high quality butted spokes.
Butted spokes are lighter and allow a better spoke aligningment that translates in a reduced stress of the parts and an overall stiffer lacing.
Berd spokes: Flanges are designed to properly fit Berd spokes.
All edges are well rounded thereafter "Tangential Straightpull Inserts" are not necessary.
Consequently adjust Table A lenghts as follows:
- subtract 2mm from Table values if "Without Tangential Straightpull Inserts"
- keep values on Table if "With Tangential Straightpull Inserts"
Berd Tangential Straightpull Insert

WARNING: never modify even slightly the flanges of Extralite hubs not even their surface finish.
5
Lacing: correct lacing patterns with straight-pull spokes must be tangential, exactly as shown below
(and not as the traditional 2 or 3 crossings used for elbow spokes)

Spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.
