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!

What does that monospoke wheelset weigh in at?

More importantly, the photo resolves the question of the ages. Clearly
the the wheel is "hanging" from the spoke, not standing on it!

Sheldon's "Citroen" monospoke wheel does indeed hang from the spoke.
The tension in the spoke is equal to the weight that the wheel supports.
Until the wheel rotates, that is.

At that point the hub is no longer in the center of the wheel, at which
point it is no longer a wheel, by definition.

But is way light, way cool, and I expect to see them on eBay in short
order.

I occurs to me that a monospoke wheel, just like Citroen's steering
wheel, could be built. But it not function in the way that a
tensioned-wire spoke wheel does. The single spoke would be an
unsupported beam and would be much heavier than the bike and rider it
carries to stay roughly round in use. Not so kewl.

Why don't you just make it so that at the point where te spoke meets the
wheel, it is free to slide around the rim. Then as long as the spoke
alwas points straight down, it will provide support and the wheel then
rotates freely. I would suggest using a maglev bearing at the rim to
reduce friction.

Top ten questions from prospective customers at Harris Cyclery:

10. Can you use disk brakes on it?

9. To true these wheels, do you loosen, or tighen the spoke?

8. What spoke tension did you use?

7. Doesn't spoking on the non-DS put too much strain on the hub?

6. But Sheldon, doesn't spoking the wheels x0 cause flange failure?

5. Why didn't you use an aluminium nipple?

4. Will using standard-pitch jockey wheels damage the chain?

3. Are you using a compact chain because you have a compact geometry
frame?

2. Any danger in greasing the nipple when "lacing" the wheel?

1. Run out of ideas. ANYBODY??

Here it is:

1. I have an old DuraAce 39-speed cassette. What width spacers do I have
to have on the cogs to make it work with the Record-40 brifters and rear
der?

Nah, a bit weak. Who else?
