I bought an '70s Bianchi for my wife that was full ARx....I remember getting it all ready to upgrade it and well....never did. They were very, very reliable. My wife rode that heck out of that bike and I never had to replace a thing other than cables, tires, and tubes. It wasn't high-zoot but it worked well and was reasonably "light".
