The efforts on the 600 shifters paid off, they look good and complement the rest of the bike.
Looking forward to seeing the final results. I started my bike maddness with a new 600EX crankset/BB kit as a teenager. It was slightly older than yours, with the Nuovo Record style chainrings. That 52x39 combo worked so well. It's still in use on my brother's Raleigh/Triumph roadracer.
