Just finished another build this morning. Needed a disc rear wheel so went ahead and cannibalized one of the rims off a pre-built. Getting better at it too, starting from lacing to complete balanced and trued takes about 2.5 hrs. Pardon the mismatching nipple, trying to use what I have instead of ordering more. The spokes actually came "used" from Yellow Bike Project, found them bundled up with a rubble band, all 285mm, paid close to nuthin' for them. According Spoke Calc, Left spoke length: 286.3, Right spoke length: 285.4, decided that they are close enough so use the same length (285) for both sides, worked out fine.
