HyperRear / HyperCamber

wheel-building

Here you find all the necessay 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)

 

Maximum spoke tension:

HyperFront / HyperLefty

Right side 70 kgf +/- 10kgf

Disc side 110kgf +/- 10kgf

HyperRear / HyperCamber

Drive side 120 kgf +/- 10kgf

Disc side 70kgf +/- 10kgf


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 lenght 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.

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)
