These rants are getting old.
I think each time I see one I will counter with an opposite experience....
After more than six years of regular use, including thousands of miles of fully loaded touring, much of which was in hilly and mountainous areas, I needed some drivetrain components (chainrings, cassette and chain) of my LHT replaced. I went to a LBS I use often. They listened to what I wanted, did some research based on my desires and found me a great set of quality chainrings in black that looked far better than the original silver ones. (The cassette and chain were no-brainers.) Parts were ordered and installed in a short period of time, and they performed flawlessly on last month's 800+ mile tour in MT and ID.
