Spoke length

Mavic Open Pro / Record Hub. What spoke length do I need?

[Jaq]

What's the rim's ERD? What kind of Campy Record hub & how many holes? What's the flange height? Rear wheel or front? If rear, 135 spacing, 130, or 126? Drive-side or non-drive side?

What kind of lacing pattern? Radial, Cross 4, Cross 3, Cross 2, Crows Foot, 3 Leading-3 trailing?

There's a lot more to it than "this rim and that hub." You can google up any of a dozen or so "spoke calculators" and enter the information and have them spit you out a number.

And you'll learn neat things in the bargain.

Mavic Open Pro / Record Hub. What spoke length do I need?

Drilling? Number of crosses? Which hubs? freewheel? Casette, 8s? 9/10/11s?

ERD of OpnePro is 602mm for the gent above but all his other ? certainly apply.

use this spoke calculator, it has the dims needed but YOU need to know what components your using. http://www.prowheelbuilder.com/spokelengthcalculator/

If you ask such a basic question without the details are you experienced enough to build a wheel?

People want to help here, but often I see posts on various forums that the requester seemed to just "tweet" the request in 5 words, letting everyone trying to figure out what their need is.
