HyperBoost/Smart3 F - HyperBoost/Smart3 R - HyperLefty3
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 spoke length on table
3) See specific info about spoke type
4) 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.

"Spoke-End Diameter"
Rim manufacturers 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 too.

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.
3
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.
Berd
spokes
Flanges
fit Berd spokes, since edges are well rounded "Tangential
Straightpull Inserts" are not necessary.
Adjust Table A lenghts as follows:
Adding
"Tangential Straightpull Inserts":
use same values on Table A
WITHOUT
"Tangential
Straightpull Inserts":
subtract
2mm from table values.
WARNING: never modify
even slightly the flanges of Extralite
hubs not their surface finish.
4
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)
Warning: spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.
