In an imaginary post apocalyptic world bicycles will have a place, but I doubt very much if you're going to be able to find parts to fix a Shimano derailleur.

Trust me, Apocalypse or not, there will be plenty. (and if we run out we can always switch to Campy)
Now you have the basic shape and the more advanced knowledge of steel, you can ask almost any blacksmith to produce bike parts. The shape can be used to make a mold and the quality of steel dependent on the craftsman.
The cheapness of modern parts comes from their high volume, but the basics of a bike are not going to be lost. The knowledge of materials was not their but the craft skill is visible in bronze age craftmanship. By 1900 Parsons were turning out turbines with tollerances of 1/1000th of an inch, that is several orders of magnitude beyond what is necessary for a bike. So we would need to go way beyond the late 19th century of technology to no longer be able to produce a decent shifter (discounting fixies).
There would certainly be enough to scavenge off the old bones for many years to come as you busy yourself prying dead fingers off of rusty handlebars.
One of the things though about modern societies is that the knowledge of doing things is held in very few hands. Also, that knowledge is usually fragmented across many individuals and is critically dependent on current technologies which are themselves vulnerable to mass systematic failure of specialized components that are often sourced halfway around the planet.
While engineering, manufacturing and assembling a modern metal bicycle might at first seem like a rather simple enterprise; I couldn't imagine any one person right off hand that could accomplish the task. Specially if they were handicapped in primitive conditions.

Duh.
$this->bbcode_second_pass_quote('', ' ')You only have to imagine a world with no or limited electrical service to get the idea.
Even then you are wrong.
PO.com is full of people who know what cannot be done, but have never spent any time in a workshop surrounded by competant fitters.
But they are certain they are right. I guess they have a better imagination than me.

Excuse me, I personally know many, it's been my life's career, most all of them could not function outside of their present experience.

')Post peak to me simply means less traffic, more public transport, small engined cars and far fewer SUV types.
Peak oil happened in 2005.
It would be nice if it did mean less oil, and less traffic.

It does, just the drop in traffic volume is still above congestion rates in many places and getting worse in the BRICS nations because they are growing at the expense of the OECD countries who are reducing their consumption. A few more Percent in the drop in oil supply and the affects will become VERY noticeable when the peak time congestion all but disappears from many of the current "pinch points".
