I'm not sure if scans of these instructions exist elsewhere, but they were included with the bike when I bought it. I thought it could be useful to share them here.
I also made some progress on the ST1000 to get it riding. Bought cable guides from vintagecannondale.com to replace the middle one and ordered a pump peg from eBay for the headtube as the original was missing. It'll probably be a slow build over the winter. I'm thinking faceted fenders and 32mm tires — maybe some burgundy/gumwall Fairweather Travellers. Unsure of what to do with the frame pump color, so it's staying orange for a little while longer. I certainly need a different saddle and longer stem. Need to decide on bar tape color as well as order 48/38/28 chainrings. I'm thinking of running a gold chain as well and maybe upgrading to a 9-speed cassette.
