Couple of thoughts:

1. I am pretty busy of late but am going to grab a few bits and bobs and photograph them with a general idea of what could be done to make a full retro retroshift system using ONLY vintage parts. Think of it as what Moser would have used if retroshift had been around back then.

Give me a few days and I will have something for you all to chew on.

2. In the mean time I was thinking while our model tw0 is not vintage it will be a nice option for people who want to have 'STI' on a vintage bike. Might let you use your vintage shift levers and also give a vintage look with the cable routing?

Cheers!
