I am considering buying a wheelbuilder cover but I need to know if I have 24 or 24 paired spokes. These are standard issue 404s from Zipp. on the non drive side there are spokes 12 going straight out fron the hub, and on the drive side there are 12 that cross once over each other. Is that 24 or 24 paired?
24 spoke: radial non-drive, 2-cross drive side.
The wheel you have is not a paired spoking pattern. Paired spoking is where spokes on opposite sides of the hub meet near each other on the rim, a standard spoking pattern (such as yours) has the spokes equally spaced around the rim.
Paired spokes are a special rim design (like Rolf wheels) and are very visually distinctive. Zipps are not paired.
