CyberFront SP-X 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 (left and right side) on table A

(All measures are expressed in mm)

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

4) Notes about different spoke materials (Butted-steel, Berd, Carbon-metal)

Maximum spoke tension: 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.
Example 1: your "spoke-end diameter" is 563mm use 286mm spoke.
Example 2: your "spoke-end diameter" is 602mm use 305mm spoke.
Example 3: your "spoke-end diameter" is 604mm use 306mm spoke.

Left and Right side - Straight-pull spokes

Lacing: correct lacing patterns with straight-pull spokes must be as shown below.


4) Spoke Materials

Steel Spokes: Hub f langes accept standard spoke heads however we recommend to use only high quality "butted" steel spokes.
Butted spokes are lighter and allow a better
spoke aligningment that translates in a reduced stress of the parts and an overall stiffer lacing
.

Berd spokes: Flanges are designed to fit Berd spokes too.
All edges are well rounded thereafter
"Tangential Straightpull Inserts" are not necessary.
Consequently adjust Table A lenghts as follows:
- subtract 2mm from Table values if "Without Tangential Straightpull Inserts"
-
keep same values on Table if "With Tangential Straightpull Inserts"

Berd Tangential Straightpull Insert

Carbon-Titanium Spokes: Hub flanges accept composite spoke that feature standard thin metal ends (Titanium or Steel) since
the short metal head should be well bendable in order to get the spoke correctly aligned with the rim.
When lacing Carbon Titanium spokes make sure to add this important step to the lacing process:
- As spokes are fully tensioned
settle spoke heads (before final truing).
- To
settle spoke heads push the metal area of the spoke immediately after the hub flange with
a small wood/plastic rod in order to settle them permanently to the exact direction.
- Then execute the final truing
.

Note that cabon-metal spokes are extremely sensitive to the following:
- Twist: thread-to-head section should never get twisted not even during lacing.
- Spoke to nipple-alignment: each nipple should get perfectly aligned with its spoke.
- Avoid exposure to hi-temperatures as behind car windows under hot sun, transport, storage etc.
- Avoid hits with any hard object during riding, transport, storage etc.

 

Fully respect these basic info before and after installation.
