I agree with you about 90 percent of the time. Best way to learn it so do things yourself like repairing a bike. But there is a big difference between repairing an inexpensive frame and a high dollar desirable 531 frame. That is why I recommended taking it to a LBS. I'm all for DIY but I also know that some people have their limitations and its probably not the best idea to practice on something expensive. If the OP were near me, I would take him to the local bike coop and show him how to properly install a crown race and let him do it with supervision. I really am not too concerned with the installing of the race, its the setup of the bearings that more concerns me for the bike's sake. Sounds like the Op has some nice parts, I just don't want them to get damaged.
