Specialized equipment is good stuff! I like your setup, DRW. You sound like me: take more care of your bike than your car!
I had my van's gearbox replaced yesterday and had to fork out about A$1500 for it. I flipped and pulled my face at the price, yet I wouldn't think twice forking out A$1000 for a new Campy groupset! My wife reckons my logic is twisted. Ahhh, life is good! ;D
