Hyper3 wheel-building instructions
Wheel building instructions for
HyperBoost3 F / Smart3 F - HyperBoost3 R / Smart3 R - HyperLefty3
Here you find all the necessary instructions to build up your dream wheels with pre-calculated spoke lengths.
Follow instructions step by step:
1) Measure your "Spoke-End Diameter"
2) Find your spoke length on table
3) See specific notes about spoke and rim types
4) Follow correct lacing pattern
Rim offset:
2-3mm of rim offset influences the spoke length for an average 0.3mm only.
You may neglect it or eventually just use that tiny amount for rounding lengths to the available spoke size.
Maximum spoke tension:
HyperBoost3 F - Refer to specific manuals
Spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.

"Spoke-End-Diameter"
Rim manufacturers 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 too.

Table A
We list "spoke-end diameters" every 5mm step. If your "spoke-end diameter" measure is in between 2 steps adjust your spoke length consequently.

Important Notes
Rims: We consider rims with 2-4mm of offset.
In case of symmetric rims you may add 1mm to front-right and rear-left sides.
Steel Spokes: Flanges accept standard spoke heads however we recommend to use only high quality butted 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.
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 values on Table if "With Tangential Straightpull Inserts"
Berd Tangential Straightpull Insert

WARNING: never modify even slightly the flanges of Extralite hubs not their surface finish.

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

Warning: spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.
