Lacing instruction

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 radial spoke length (right side) on table A

3)Find your front spoke length and lacing pattern (left side) on table B

4)Find your rear left side spoke length on table C

5)Find your rear drive side spoke length on table D

(All measures are expressed in mm)

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

Maximum spoke tension: Refer to manual

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.
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 563mm use 271mm spoke.
Example 2: your "spoke-end diameter" is 567mm use 273mm spoke.
Example 3: your "spoke-end diameter" is 569mm use 274mm spoke.

Spoke-End-Diameter

How to measure "Spoke-End-Diameter"

Spoke-end diameter is not ERD !
Spoke-end diameter depends on your rim and nipple type and length.

Below you see how to measure SED for both nipple types:
External nipple configuration
Internal nipple configuration

Take measures very precisely because a well correct nipple/spoke assembly accepts a spoke-length tolerance of +/-1mm only.
(All measures are expressed in mm)

External nipple configuration

1) Insert two J-spokes (random size) with the nipples (of your final build) into 2 opposite rim holes.

This simple trick helps to keep spokes aligned and slightly tensioned.

2) Precisely measure distance between nipples.

Be careful to take measure between the 2 nipple-ends.

3) Add 2x by the nipple height (of your final build) to the measure above.
This gives "Spoke-End-Diameter".
Note: with slotted nipples measure height inside the cut.

cutted nipple

Internal nipple configuration

You can get the necessary data following the procedure below:
1) Precisely measure outer rim diameter (A).

2) Insert a nipple of your final build into a hole (use a spoke to hold nipple in position).
3) Precisely measure distance between nipple-top and outer rim diameter (B).
