CyberFront SP 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)
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.
Example 1: your "spoke-end diameter" is 563mm use 271mm spoke.
Example 2: your "spoke-end diameter" is 567mm use 273mm spoke.
Example 3: your "spoke-end diameter" is 569mm use 274mm spoke.
Radial lacing only.
