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 on table A & B

3)Find your rear spoke length on table C

(All measures are expressed in mm)

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

Maximum spoke tensions:

Hyper JF - Refer to manual
Hyper JL - Refer to manual
Hyper JR - 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.
