HyperLefty 80g
Tech info
Description
Hyper engineered Lefty compatible hub.
Stainless high load capacity & low friction cartridge bearings (individually matched).

HyperLefty-2 and HyperLefty-3 are compatible only with Lefty 2.0, Ocho and SuperMax forks, it mounts directly without adaptor however none of the newer 2 hubs can fit the elder fork models in any way

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.
Spoke-end Diameter
How to measure "Spoke-End-Diameter"
Spoke-end diameter depends on your rim and nipple type and length.
Below you see how to measure SED for both nipple types:
External nipple configuration
Internal nipple configuration
Take measures very precisely because a well correct nipple/spoke assembly accepts a spoke-length tolerance of +/-1mm only.
(All measures are expressed in mm)
External nipple configuration
1) Insert two J-spokes (random size) with the nipples (of your final build) into 2 opposite rim holes.
This simple trick helps to keep spokes aligned and slightly tensioned.
2) Precisely measure distance between nipples.
Be careful to take measure between the 2 nipple-ends.
3) Add 2x by the nipple height (of your final build) to the measure above.
This gives "Spoke-End-Diameter".
Note: with slotted nipples measure height inside the cut.
Internal nipple configuration
You can get the necessary data following the procedure below:
1) Precisely measure outer rim diameter (A).
2) Insert a nipple of your final build into a hole (use a spoke to hold nipple in position).
3) Precisely measure distance between nipple-top and outer rim diameter (B).
This is the correct caliper positioning inside the rim (don't cut your rim!)
4) A-2B = "Spoke-End-Diameter".
