Bike transmissions: Derailleurs are easy to understand.
Internal gear hubs are more complicated. (When I was teaching,
I had our machinist do a cutaway of a Sturmey- Archer AW hub
and mount it on a display stand near an explanatory poster, so
interested students could see what made it work.)

Rohloff 14 speed gear hubs are an order of magnitude more
complicated than AWs. But this new gizmo makes a Rohloff look
like child's play. It's a true continuously variable
transmission, with an infinite number of gear ratios, that is
completely gear-based. No slipping surfaces, and supposedly
minimal friction losses.

Brilliant and clever! Thank you.

I can only see complexity, cost to fabricate and weight as
downsides, none of which would be deal breakers for some
applications. Motor power for example.

Sort of the inverse of fixed, which are dirt cheap, light and
reliable at the cost of zero gear variance.

I have to admit I don't know much about modern electronic control
slushboxes (except to avoid them) but the geared CVT is much more
complex than what I drive* and infinitely more complex than what I
most often ride (fixed)

Yeah I saw that. Old page format, never updated to modern protocols.

I absolutely love to see you crying about my wealth bvecause you have
none.

 
And you still haven't explained how you went from being broke and living
on social security in 2013 to reaping a $12000 monthly income off your
investments with no other source of income.
 
tears of laughter tommy....

Rather than lying about everything that you can, I'll just show them: I
never said I was broke and I never said that I was living on Social
Security alone. I said that during the Great Recession that occurred
during Obama that I lost half of my investments that weren't made up
during Obama's time in office with his 25% inflation over his 8 years.

During Trump I regained my investments BACK to what they were before Obama
and then with far better investment advice I grew it to $1.1 million
despite the 22% inflation during the 4 years of Biden.

I understanjd why you deny that reality is real but then you have nothing
because you do not even have a passing clue of how to handle money. The
alligator tears you cried when I said that I had been making $233,000
dollars a year showed that you simply canmot believe that a real engineer
can make that sort of money. And even in these times of hardship I have
been offered $200,000/yr to move to Texas.

Too bad you can't get anything right - there isn't anything you won't lie
about. Except that you seem to be so set on me being a drunk that you must
be. That you never once referred to having a wife until you had a need to
"prove" that you're not a queer. Poor Liebermann couldn't even support
himself so he couldn't find a wife and everyone else that is married
mentions their wives now and again. But your supreme egotism is the very
mark of homosexuality and even if you're not queer you will surely become
one to torture some insecure person.

I had far too much experrience with interviewing queers dying from AIDS to
not recognize the symptoms in you.
