CyberFront & Rear SPD-3 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
(All measures are expressed in mm)
4)Lace the wheel respecting correct lacing pattern
Maximum spoke tension: Refer to manuals CyberFront SPD-3 CyberRear SPD-3
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 B
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.
Lacing: correct lacing patterns with straight-pull spokes must be as shown below.
