Wheelbulid of Cyber SP-B SP-2B

CyberFront SP-B / CyberRear SP 2B+ wheel-building

Here you find all the necessary instructions to realize your dream wheels with pre-calculated spoke lengths

Follow instructions step by step:

1)Measure your "spoke-end diameter" (not ERD)

2)Find front hub spoke length on table A

3)Find your rear spoke length (left side) on table B

4)Find your rear spoke length and lacing pattern (drive side) on table C

(All measures are expressed in mm)

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

Maximum spoke tension:- Refer to manuals of CyberFront SP-B and CyberRear SP-2B

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

2)CyberFront SP-B

Radial lacing - Straight pull spokes (any drilling count)

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

3)CyberRear SP 2B+

Left side- Straight pull spokes
