I don't understand the attacks on the half step plus granny. Yes, modern equipment has rendered it obsolete. But for classic bikes, what is the proposal?

Yes, you need to shift a lot. And the gear charts on the stem are nerdy. But you can dial in a really great set of ratios using classic era components and building custom freewheels. With no overlapping gears. Plus you can set up a super low granny at no detriment to all the closely spaced ratios in your power range. In my touring experience, you can't have enough ratios spaced closely (say every 3 gear inches) and evenly around 65-70 gear inches and it is a good idea to have a gear as low as 20 gear inches. What people forget to consider is that tendonitus and other physical problems can flair up on a long tour and you can either stop and rest, abandon or take it extremely easy.

My favorite for a cheap and acceptable front derailleur for touring setups is the Campagnolo 980.
