Obviously, this system is intended for the elite, not for hacker mechanics.

(Without even looking at it... ) Obviously.

But most bikes get maintained by hackers. Seems like anything requiring thousandths-of-inches precision is a bad idea.


For most bikes, sure.

(Your inner curmudgeonly luddite is showing.)

I had an engineer friend who once worked in military helicopter design. He said that on the wall of the engineering design room was a rather small collection of tools, with a sign saying something like "It must be repaired using only these tools."

Perhaps bike component companies should use that same trick, with the tools being just one screwdriver, a rusty crescent wrench, a bent pair of pliers and a hammer.


That should do to repair your snow shovel, but some of us aren't
contrained to the driveway and neighborhood backstreets when the
weather is less than optimal.

Lou is not alone.

Some mercs had rear hydropneumatic suspension, presumably for the
self-levelling.

Rolls Royce were another user.

Didn't know about Jaguar - which bits did they do?

Here's an innovation risk...

The spring was traditionally a steel coil, and now it seems a migration
to a CF leaf spring.

Is there already a brake that uses a CF leaf return spring?

I wonder what the risk is?

Could there be CF leaf springs used elsewhere on a bicycle? Perhaps in
the brakes (calipers and levers) for return springs?

Depending on the car, some or all of self leveling rear suspension,
brake booster, and power steering fluid.
