comment Does Bike or Rider Weight / Groupset affect cruising speed on the flat
The more you weigh, the more power required to "get to" a certain speed. But once you are travelling at a constant speed, the only thing you have to provide power for is wind resistance and friction (rolling resistance of wheels, bearings and other things). A heavier rider, assuming the same aerodynamic profile and friction forces will actually not require more energy to maintian a constant speed on a flat surface.

comment Would an original Abloy padlock and [toughened] chain make a good bike lock?
@qarma, why don't they make locks out of the same material as the chain?

Safety is all relative, and depends on where you live. At my office, I see plenty of people with cable locks, even though they are known to be easy to cut, and yet still no bikes have been stolen. Some other places you wouldn't be safe leaving your bike unattended no matter which lock you choose.

comment What could be the reason for stem this far away
Perhaps the previous owner was too tall for the frame and was trying to compensate with a longer stem.

comment Are there front looking mirror options?
It would be very disorienting (and probably unsafe) to ride like this, because you would be seeing a mirror image. Also, your field of view would be quite limited, or it would be distorted because you'd . Not only that, correct me if I'm wrong here, but wouldn't the image be vertically flipped?

comment How much does non-ideal frame size matter?
Is it too big or too small? It's often easier to make a small bike bigger than to make a big bike smaller.

comment ANT+ to Bluetooth Low Energy bridge?
What extra functionality do you get from tracking on two devices at once? The Garmin Edge 810 is a very high end device. What features does the iPhone offer that you feel the need to track on 2 separate devices.

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.
