I've got a rear Excel rim that is starting to look pretty used from rock dings and tire changes. I want to order a new rim, reusing the OEM spokes and hub. I don't think re-spoking the rim will be real difficult but I am concerned about balance and alignment as the spokes get their final tightening. Has anyone got advice about what sequence to thread the spokes and the order in which the spokes should be tightened? Techniques for checking alignment and balance? Thanks in advance.
