I didn't need another project, but I have one now. I picked up a Schwinn Premis frame yesterday. S/N C889724 which I take to mean it was an '88. There are some chips and scratches which means it's not too nice for me to ride around.
I'll need to put in a new headset and maybe a bottom bracket. The crank is set up for half-space gearing. I'm not sure if I will keep that or not. There is an NOS 7-speed STI downtube shifter set on it and I have a brand new 7-speed cassette (12 to 28) so I will have to do a little work in Sheldon's gear calculator to see if the chainrings will play well with the cassette.
These came with SunTour derailleurs, right? I don't have a spare Shimano RD handy. I was envisioning maybe a long-cage Shimano 7-speed RD. Is that going to thread into the hanger?
