I am torn over the Centaur components. I don't have that much to splurge, but I want quality parts that will perform well and live long. Some people told me that while Centaur is decent I might want to make some upgrades. With that in mind, I would upgrade the rear derailleur and shifters. But what about the BB and crankset? Is it worth getting Centaur or would I be better off with Chorus? With not having that much cash to throw at this bike are there any areas I should upgrade? Thanks, your thoughts would be most appreciated. Cheers.
