CyberFront SPD(2) wheelbuilding
Here you find all the necessary instructions to realize your dream wheels with precalculated spoke lengths.
Follow instruction step by step:
1)Measure your "spokeend diameter"
2)Find your front spoke length (right side) on table A
3)Find your front spoke length (disc side) on table B
(All measures are expressed in mm)
4)Lace the wheel respecting correct lacing pattern (see below)
Maximum spoke tension: Refer to manual
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.
Warning:
spoke lacing and tensioning require skills and experience,refer to an expert
professional wheel builder for these operations.
1)"spokeend 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 "spokeend diameter" and rim drilling.
Spokeend
diameter depends on your rim internal diameter and nipple type.

Table A
Note: We
list "spokeend diameters" every 5mm step. If your "spokeend
diameter" measure is in between 2 steps adjust your spoke length consequently.
Example 1: your "spokeend diameter" is 563mm use 271mm spoke.
Example 2: your "spokeend diameter" is 567mm use 273mm spoke.
Example 3: your "spokeend diameter" is 569mm use 274mm spoke.
