• Hello,
    I'm building a wheel set on campagnolo pista hubs laced to mavic open pro.
    I want the front wheel laced to radial, but the menual says not to lace radial on campagnolo pista hubs.
    Thoughts on the matter?

    Yes, don't lace radial if the manual says so... seems pretty obvious. You invalidate the warranty.
    If you don't care about the warranty then you can take a punt, just keep the tension within reason (800-900N at the very top) and inspect frequently for cracks.

    PS: a crack will always develop perpendicular to the load (90 degrees to the spoke)
