Great ideas to mull.
So ... microdrive uses a bittier chainwheel and a bittier cog. That would
achieve my goal of not having a big-looking cog. That stuff still
available? Sheldon, Mashbar, Preformance don't list microdrive components.
In fact, I am not finding a lot of tech talk about microdrive.
W/r/t a hub gear -- yeah, that's a cool idea. I wouldn't even need a large
range, even a three-speed would work. I have laced up a couple wheels with
tolerable results. So the questions expand to:
1. Can microdrive components (chainwheel & cog) be used on the Motobecane
Messenger w/ its 130 BCD crank? I don't want to spend much on $wapping out
the crank$et.
1a. What's the smallest chainwheel that can be used on the TruVativ Touro
(130 BDC) crankset?
2. Is there a reasonably affordable geared hub? in case I am feeling all
adventurous and spokey and stuff?
