CyberFront & Rear SPD-3(+) SPC3+ 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 hub spokes length on table A
3) Find your rear spokes length on table B
4) See specific notes about spoke and rim types
5) Lace the wheel respecting correct lacing pattern
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 B
We
list "spoke-end diameters" every 5mm step. If your "spoke-end
diameter" measure is in between 2 steps adjust your spoke length consequently.

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 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"

Lacing: correct lacing patterns with straight-pull spokes must be as shown below.

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