Quite the #bicycle seat I passed in 2012.

This is by far the best resource for sourcing good locks and for learning how best to use them.

#ebikes could benefit from #standardisation. like, when do we get usb-c chargers?
but for accoustic #bikes, availability of parts and #maintainability are usually not an issue, even for older bikes.
which #bicycle parts have you been unable to find?
@InkySchwartz @bikenite Wow, I’m actually on time for #bikenite ! Watching the replies from south central Minnesota as usual. If you can find a place to use it, please do so. Hopefully it will inspires others. To #bike #bicycle #BikeTooter

Slowly getting to the point where I'm happy with the Eddy Merckx Strada OS bike project.
New alu Fulcrum racing 4 wheels work well on this frame. They balance aero with weight nicely, although dedicated climbing wheels might be something I'll look into.
Final thing will probably be Ritchey Butano handle bars, replacing the Ergomax setup, which is a bit too tall and wide.

Accidentally bought a kickstand for a 19" frame. I can't use it. I just barely missed the return window. It's yours for $10 if you need it.
Let me know if you're local, and you're interested in buying them.
Cash preferred, but I have PayPal.

* Any lay-person resources to learn more?
* W/gyroscopic forces, the turning CoE moves forward of the wheel centre, even > r (e.g. the demise of delta motor trike.) Is this greater w/ larger diameter?
There are many books that attempt to explain the physics of bikes, this might be the best: mitpress.mit.edu/9780262538404…
* Is larger diameter generally better?
It depends. Bigger gyroscope is great for straight-line efforts and rolling over bumps, smaller is better for turning, and not hitting your foot with it.
* Why is the standard #bicycle #wheel 700c / 26"?
History, and trial and error. In US, the bicycle became a child's toy, 28" adult size, AKA 700c, died out in early 20th century. When hippies wanted fun, they grabbed juvenile bikes from the 1940s, thus the mountain bike, thus 26" popularity.
* Is this a factor in drive wheel vs steering wheel? I.e. if they must be different, which should be larger?
Same size good. Ride.

@Amgine asks about rolling resistance:
