Bikes: A bunch of old bikes and a few new ones

Making the gearing changes (14-34 in back, 3x up front) for the hills 'round here came first but as the original friction shifters worked so well (still!) I never felt need of changing anything in that mech.

My Kona Dew+ has a thumb shifter though so I'm familiar with the concept albeit in a limited way. After acquiring first a Spesh Tarmac last year, then a Diverge late this year, I've pretty much burned through my 'disposable' income budget for biking stuff... but always interested in learning more about things yet unexplored.
Thumb shifters are great for flat bars. Sunrace makes a good thumb shifter that is inexpensive. I installed a set on an '87 Rockhopper I built for my nephew. He's been riding that bike now for over 5 years with no probems:

I used indexed thumb shifters on my 1993 Trek 750 which I hope to take out on a ride on Christmas if this weather holds up. These pics are from a ride I took on Christmas day a year ago:
