I have a Rock'N'Road from the 80s. It has WTB flared drop bars and Shimano mountain bike shifters
set up to work on drop bars. I have the Bruce Gordon rear rack and used it for about 10 years to
commute to work. It was great and I only replaced it so I could get a bike that was more comfortable
on San Francisco streets (an Otis Guy beam bike). I ride it ocassionally and let visitors use it.
They are very happy with the responsiveness of the the frame.
