I was looking at the SKS chain guards.

They look quite sharp, but ...

The weak points are circled in blue and red.

Exposed chain and sprockets are exposed to dirt and dust.

There’s always belt drive, if you want different problems.

Hard to use a derailleur system with a shaft drive...


Sir hasn't been keeping up at the back!

Nope, that was discussed some time ago. If I remember the final
outcome, someone made the decision that it wouldn't work! :-)

Touché.

However, if I was to shift into full pedant mode, the Oxford dictionary
states that a derailleur is “a bicycle mechanism that moves the CHAIN out
and up, allowing it to shift to different cogs.�, so perhaps I could stand
by my original statement.

I would, simply because you probably could get a chain guard the ceramic
speed :-) Wonder if will ever see the light of day anger.

I looked at belt drive and other chainless systems.

They have far fewer gears and are very expensive.

I have never seen anyone riding one, which makes me do some wondering.

At one marina I lived at, in Phuket, Thailand, there was a guy had a
belt drive, single speed, bike. I asked him, one time, how the belt
lasted and he said he didn't know as he had "only owned the bike for
about five years".

That's a long time. My chain does not last that long.

Well, of course riding around in a marina isn't quite the same as
crossing the U.S. :-) But they guy did seem to ride it here and there
daily.
But think of an automotive timing belt. Every 50 - 70,000 miles?

A big part of my chain getting dirty is from the yard workers using leaf blowers.

I have my bike covered with a tarp, but the dust still makes it under the tarp.

I have ordered a DasBike Bike Cover. It completely covers a bike.

The (only) good part about those turd dust hurlers is that they are so noisy
I can usually hear them way before they get dangerously close to the spot of
the parked bike.

Ranked #20 in bike cover sales. Impressive how an stationary exercise bike
(dust collecting) cover is selling almost as well at a close #22 -- should
really be mandatory with each sale to fit statistics of stationary bike usage.

What in the world are these leaf blowers? From the sound of them they
must be something to remove leaves from your yard, but where do the
leaves go? Into the neighbor's yard? Out into the street?

It seems a real puzzle :-)
