Cyber SPD 2 Wheel building - Lacing instruction
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 radial spoke length (right side) on table A
3)Find your front spoke length and lacing pattern (left side) on table B
4)Find your rear left side spoke length on table C
5)Find your rear drive side spoke length on table D
(All measures are expressed in mm)
6)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)"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.
