For reasons I won't bore you with, I'd like to try a half-step and granny
gearing system. I'm willing to entertain suggestions that it's ill-advised,
but I'd like to try it for myself all the same, and I have most of the parts
I need to get started.
Likely gearing will be 45-42-granny at the front, and either
11-12-14-16-18-21-24-28 or 12-14-16-18-21-24-28-32 (eight of nine) at the
rear.
Questions:
What front derailleur would you choose, and why?
Given the above, what size granny would you shoot for?
Shifters will be either older Campag Ergos, Shimano barcons, or downtube
levers, so front indexing isn't an issue.
Thanks,
James Thomson
