CyberFront SP-X 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 (left and right side) on table A

(All measures are expressed in mm)

3)Lace the wheel respecting correct lacing pattern (see below)

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 286mm spoke.
Example 2: your "spoke-end diameter" is 602mm use 305mm spoke.
Example 3: your "spoke-end diameter" is 604mm use 306mm spoke.
