one thing that is VERY important is the direction of the spokes in the wheel. You have what is know as "Static" spokes, and "tension" spokes, tension spokes are the ones on the outside of the hub, the ones you put in last. It is critical that these spokes follow the turning direction of the wheel, so that if you are holding the rear wheel in front of you with the drive side facing you, these spokes goes from the hub to the left, and to the rim. Otherwise the rim is not correctly under load when driven. other things to consider, is starting right on the hub and spoke holes in the rim, are they in line or offset?
