I don't believe the Pace hubs were designed to run radial lacing,not many normal spoke hubs were/are,I'm running radial lacing on a bontrager/chris king front wheel which bontrager think is fine but king doesn't agree with.
The problem is radial puts the same stresses as 3x on a much smaller area of hub flange and the weight savings are very small,when I had my other bontrager/king wheel rebuilt I went 3x.
