Open Source Electronic Derailleur
Tiagra? Yikes. I think all the effort warrants Ultergra.
I plan to for the next version. Since the modifications are permanent I decided to try it with a cheap derailleur first.
Is this the first step towards a automatic shifter?
That wasn’t my plan, but a lot of people have requested that feature. I guess folks who ride casually would enjoy it so I’ll add it to the backlog.
