comment Bicycle keeps 'skipping a beat'
Define better what "skipping a beat" refers to. Also, what are you lubricating to temporarily stop the problem.

comment Is it rude to take the lane, then filter when encountering congestion?
I think that the biggest thing to take into the consideration of what happens when the passing party makes a mistake. If a car clips a cyclist travelling 30 km/h faster than the cyclist, the cyclist could end up dead. If a cyclist passes a car, and hits the car, you might scratch the paint, or at worse, break off the mirror. The cyclist or his bike would probably be hurt more than the car. The non-offending party (in the car), will have no physical damage.

comment Interrupter (cross) brake lever cable guide wedges?
If you know someone with a woodshop, it would be possible to easily fashion something out of wood. Would also be an easy task for a 3D printer.

comment Slipping when pedalling
If one of the cranks was slipping, the crank arms would be misaligned and this would be quite noticeable.

comment Bike Speedometer Accuracy
I think that my GPS (Garmin Oregon 450) had settings which enable you to change the frequency of recorded data points. I think there was an "auto" option which records more point when you're going faster, and fewer points when you aren't moving. Also, I assume that the "distance" traveled will vary depending on how you (or the GPS) interprets the data. If you go straight point to point, you'll always end up short. If you try to plot a continuous curve through the points, taking speed into account, you can probably get a much better estimate.

comment Tire Gauge to Avoid Over-Inflation
Canada has adopted the metric system, but everyone I know uses PSI. The correct metric unit of measurements for air pressure is Pascals. I just looked it up, and a "bar" is equal to 100,000 Pascals, or 100 KPa. So I guess that "bar" just allows people to use Pascals without resorting to large or small numbers. Although I think that using KPa would work better, as people wouldn't have to think about decimal places.

comment Tire Gauge to Avoid Over-Inflation
For those not measuring in "bar", 0.2 bar is 2.9 psi. This is probably getting pretty close to how accurate the pump is anyway. I just checked, and my pump is rated by the manufacturer as being accurate to +/- 3%. Which is 3psi of variation at 100psi. I don't think that it's important to be that accurate with tire pressures. If you're making an effort to check and correct the pressure once a week, you'll be well ahead of most cyclists.

comment Unicycle touring — how common?
Guinness records states the longest journey was a double cross USA tour. However, this was done as a fundraiser, so it probably doesn't qualify as unsupported.

comment Tire Gauge to Avoid Over-Inflation
A pump or two to get the gauge up to the current pressure in he tires won't overinflate them so much that you will damage them. If you're at all worried, let a little air out with your fingers before you attach the pump, or using the release button after you have the pump on.

comment Tire Gauge to Avoid Over-Inflation
You shouldn't have to worry about the pump reading zero when you hook it up. The first pump will be mostly pressurizing the hose anyway if it is reading zero. You won't damage the tires as long as you don't overinflate them significantly. If you find they are a little overinflated, you can always let a little air out. Many pumps have a little button you can press to release some air without removing the pump.

comment When Mark Cavendish says he's sprints at 1500 watts how long is that for?
Not sure if this article is talking about instantaneous or sustained power, but it quotes 2000 watts for track sprinters and 1500 watts for road racers.

comment How should I train for a hilly ride while living in a flat country?
There are other methods of resistance you could use. I've seen runners dragging old tires behind them for added resistance. I'm sure you could do the same on a bike. Although you might want to do this on an empty road or parking lot as it would make the bike hard to maneuver. I would have concerns about a drag chute getting caught in the wheel or gears.

comment Did SRAM change/update their 10 speed PowerLink?
Check out Sheldon Brown's Page on chains. It says that for 10 speed chains, the SRAM PowerLink is called a "PowerLock", and that it is single use only. Posting this as a comment because I have no experience with 10 speed chains or PowerLinks.

comment When riding with a single pannier, does it matter which side it's on?
I have a light that mounts on the back of my rack partly for this reason. The other reason is because I have another bag that goes under my saddle which doesn't fit if I have a light mounted there.

comment How much does rider weight increase tire pressure?
Interesting way of looking at it. A road bike tire at 100 psi hardly deforms at all, so the pressure wouldn't change much. However an underinflated tire, would deform quite a bit. Of course, it would only deform until it meets the rim, in which case the rim is support you and not the tire pressure. For maximum change in pressure you'd want a large tire that wasn't sufficiently underinflated such that you could get maximum deformation.

comment Single pivot brake with handlebar levers (Resurrecting an old Colnago)
@Batman I would think that the stopper at the lever end of the cable doesn't fit though the brake levers meaning than you wouldn't need the old drop levers. They may even be designed to properly hide the stopper.

comment My bike after a new spray paint, gets scratched easily
Many (most or all?) factory bikes are powder coated. Read up on Wikipedia for more informaiton.

comment Are these bikes real from Aliexpress?
Those are what are referred to as "bicycle shaped objects" (or BSOs).

comment How to replace old style cotter-pin bottom bracket with a modern one?
Both these sound like good options if you have a non-standard size. The universal botttom bracket looks quite a bit more expensive than a traditional one. Phil Wood bottom brackets are also more expensive, but from what I've heard are very high quality so they are probably worth the money. However, if you have a standard bottom bracket size, you can get a bottom for $10-$30.

comment High-quality commuting bike with “women's” frame
Could you be more specific about what you mean by "commuting bike"? People use all sorts of bikes for commuting, including Road, Touring, Cyclocross, Hybrid, Mountian, Dutch and just about any other bike. Also, Riding an hour each way in a skirt would be quite sub-optimal. Perhaps in those tennis skirts (skorst?) it would be ok, but riding that long in work clothes wouldn't be enjoyable. And you'd want to change after you got to work anyway.
