Nanodrive: The First 21st Century Drive Train System

Are you still riding on old-fashioned half-inch-pitch chain and
sprocket, like they used to use in the last century? No wonder you're
slow! Time to get with it!

Unless you're a reactionary troglodyte retrogrouch, you NEED Nanodrive,
the first 21st century drive train system! Get rid of that obsolete junk!

I love the first of April. Well done Sheldon.

I'm interested in this but concerned about backward compatability. I'm
currently using a 7 speed Shimano Hyperdrive system with 7 speed hubs,
cassette and chain. These parts are getting increasingly harder to source. I
was reluctate to upgrade to 8 speed because 9 was around to corner. Then it
was 10speed cassestte. Now it's 20 and that seems like enough. Will there be
any adapters to fit the new "20" onto my 7speed rear hub or must I replace
it along with everything else.

Please put me on the list for the next generation when fuzzy-logic
autoshifters are fully compatible. And please confer with DOD and NASA
and see when you can modify the ramjet technology for assisting us
beerkegs on bikes up the hill.

Sheldon, brilliant idea! We are all growing old waiting for CVT
(continuously variable transmission), and this is almost as good but
built on proven technology.
My question is, I have an old non-indexed 3x7 speed bike. Will I
be able to use my existing shifters and derailers, and just buy
your new chainrings, cassette and chain?
Will there be a cassette to fit narrow dropouts of 6/7 speed frames?

Sheldon, I'm disappointed! I thought when you called it 'Nano' drive you
meant something _really_ small, like tiny electric motors that could be
hidden inside hubs and bottom brackets, fueled by tiny fuel cells secreted
inside the seat tube, to give us mere mortals super-athelete type speed.
This is no more than mere evolution of existing technology, hardly a
revolution.. well, I suppose it is meant for revolution but you know what I
mean . Call it 'Microdrive' if you will, but it's hardly 'nano'drive,
don't exagerate ! .

These monospoke wheels... does the rim stand on, or hang from, the
spoke?

You can just use the old "16 of 20 on 7" setup. Get the standard
drive system, but install only 16 sprockets. It ought to work fine,
but you'll lose some of the close-ratio-ality of the nanodrive
system, or some of the range (depending on sprocket choice).

One of the funniest things I've seen would have to be the
........Citroen Monospoke Wheelset.
