I picked up an 8-speed Shimano compatible freewheel on ebay the other day. So I can swap it with the 7-speed Sachs Aris I've got on the Eddy.
Yesterday I pulled out the C-Record RD, Super Record FD, and Retro Friction shifters and spent some time cleaning and polishing them. I then installed the RD and shifters on the Colnago. I still need a FW removal tool, a spoke, and shifter cables to be able to complete the refit.
