CyberFront SL-B / CyberRear SL-2B 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" (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 specific manuals

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 SL-B

Radial lacing - J-bend 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

 

Radial lacing is allowed on internal and external flange side and only with D/B spokes (central section equivalent to Ø 1.5mm)
