CyberRear SL-2 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 rear spoke length (left side) on table A

3)Find your rear spoke length and lacing pattern (drive 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

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 266mm spoke.
Example 2: your "spoke-end diameter" is 567mm use 268mm spoke.
Example 3: your "spoke-end diameter" is 569mm use 270mm spoke.

Lacing: radial on interal flange side, use only D/B spokes (central section equivalent to Ø 1.5mm).
