Downtube to brifter upgrade?

I bought a 90's steel frame Bianchi that I put a 7-speed 105 group with indexed downtube shifter on. It came with a double Shimano 600 crankset. I'd like to upgrade to brifters, but don't know what options I have. Any suggestions?

You can get 7 sp Sora brifters on Ebay, but you must make sure they come with the housing stops that mount at the downtube shifter points. You could use 8 sp sora brifters with the alternate cable attachment at the rear der, which makes the der move the right distance for 7 sp cassette. You could spread the rear triangle to fit a 130 mm wheel, and then you would be free to use higher grade brifters.

I've done it with a 1989 aluminum Trek (originally Suntour-equipped). I got new wheels and a used 8-speed 105 group. I didn't spread the frame since it's Aluminum, just pinched the rear dropouts open a little to fit a 130mm hub.

Worked very well for me. I rode that bike for 3+ years, just moved the components to a new frame three days ago!
