Nice Frame...!

If it rides anything like mine, you should be very pleased. I never had any issues w/ handling on my SC. It always ran true & was a champ on the downhill runs. I also purchased mine as a 'frame only' from a tech friend of mine in the early 90's. Only it was a new frame, also 59 cm. Looking at the ebay pics, I see you're missing the little 'flying C' button on the stay(s)? I lost one of mine too. I you're looking for a replacement, Universal Bikes has them: Replacement Buttons

I live in the Bay Area as well. Good luck on building it up. I had a C-Record group mounted on it w/ an SRP Ti upgrade kit & Syncros BB. I believe it weighs-in at about 20 lbs. For it's size, it's really lightweight. With a good pair of sew-ups, you'll be all set...!
