WHEEL BUILDING
Wheel Building
Contact your local wheel building professional or
dealer for assistance in building the Powertap hub if
not provided as a complete wheel. The flanges are
drilled for 14 or 15 gauge spokes. Use at least a
two-cross pattern on both sides of the hub. Due to
the design of the hub, the load path is not the same
as with a conventional hub. Slotting the hub flanges
to accommodate bladed spokes is not recom-
mended and will void the warranty.
Reference a spoke-length calculator when building
a wheel not listed in the provided table.
