HyperBoost3 F/R - HyperLefty3

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

(All measures are expressed in mm)

Rim offset:
(normally 2 - 3mm) influences the spoke length for an average 0.3mm.
You may neglect it or eventually use that tiny amount just for rounding lengths to the available spoke size.

Maximum spoke tension:

HyperBoost3 F - Refer to manual

HyperBoost3 R - Refer to manual

HyperLefty3 - 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.

 


Lacing: correct lacing patterns with straight-pull spokes must be tangential, as shown below (and not as the traditional 2 or 3 crossings used for elbow spokes)
