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 spcific 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 SP-B
Radial lacing - Straight pull spokes (any drilling count)
