I’ll be riding this Bianchi so I needed to alter the gearing to be a bit easier on the legs. It had a 7-speed (13-23) Regina Synchro 90-S freewheel and an A-7 insert in the shifter. I have yet to experience the finicky nature of the Campagnolo Syncro index shifters and I want to give myself the best chance of success. That said, I found an NOS 7-speed (13-31) Regina Synchro 90-S freewheel and, going by Campagnolo’s chart, a black, B-7 insert. I cleaned and lubed both freewheels, just because.








I cleaned and polished (buffed for anodized parts) the shifter bits. I know that there’s a tool for installing the insert, but I was able to install it without much fuss. I used an 8mm socket from the underside to compress the first spring as I installed the second. It was easier than anticipated.
