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 or D
(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.

HyperRear(2)/HyperBoost
R - Refer to

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.
Example 1: your "spoke-end diameter" is 553mm use 263mm spoke.
Example 2: your "spoke-end diameter" is 548mm use 260mm spoke.
Example 3: your "spoke-end diameter" is 549mm use 261mm spoke.
Example 4: your "spoke-end diameter" is 550mm use 261 or 262mm spoke.

Table D
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)
