I recently built a wheelset using a front disc hub laced to a road rim, specifically a Shimano XT-M756 , 32 DB spokes, laced 3x to a Kinlin XR-300. Everything went fine (or I thought so) and I've been riding it and it has held up very well, no truing needed since the build.

Anyway, I noticed while doing a little cleaning the other day that I laced the spokes incorrectly as far as head in/out. I think when I laced, for some reason I thought the rotor side was laced the same as the drive side for the rear wheel. Well, I see now that is not correct.

How bad is this, and should I re-build it correctly? Spokes were dipped in spoke-prep if that matters. Thanks.
