HyperLefty 3 76g
Tech info
Description
Hyper engineered Lefty compatible hub.
High load capacity & low friction cartridge bearings (individually matched).
Black anodized body with laser etched graphics.
Flanges (for straight-pull d/b spokes): 24-28h
Weight: 76g (includes axle-bolt and extractor/retainer)
Compatibility
HyperLefty 2 is compatible only with Lefty 2.0 , Ocho and SuperMax forks (without any adaptor).
None of the newer 2.0 hubs can fit the elder fork models in any way.
Compatibilty
Nessuna immagine disponibile
HyperLefty (version 1) directly fits Slate (Oliver) and elder MTB forks. It featuress a very wide spoke camber compared to original hubs, nearly as wide as the newer 2.0 models
HyperLefty (version 1) can also fit Lefty 2.0, Ocho and SuperMax forks using the original adaptor "KH112"
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

HyperLefty3 wheel-building
Here you find all the necessary instructions to realize 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
(All measures are expressed in mm)
Rim offset:
(normally 2 - 3mm) influences the spoke length for an average 0.3mm.
You may neglect it or eventually use that tiny amount just for rounding lengths to the available spoke size.
Maximum spoke tension:
Refer to manual
Warning: spoke lacing and tensioning require skills and experience,refer to an expert professional wheel builder for these operations.
1)"spoke-end diameter"
Rim manufacturers always offer ERD figures however we warmly recommend to precisely measure the rim+nipple combination.
Basically a correct spoke calculation requires exact "spoke-end diameter" and rim drilling.
Spoke-end diameter depends on your rim internal diameter and nipple type.

Table A
Note: We list "spoke-end diameters" every 5mm step. If your "spoke-end diameter" measure is in between 2 steps adjust your spoke length consequently.
Lacing: correct lacing patterns with straight-pull spokes must be tangential, as shown below (and not as the traditional 2 or 3 crossings used for elbow spokes)
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".
