comment How has biking changed in the past 15 years?
I guess I would only add in belt drives, which although they aren't very common, are available on some mid-upper range commuter bikes.

comment How has biking changed in the past 15 years?
Unless you are talking really high end bikes, very few things have change. Things have changed more in the mountain bike market with disc brakes and suspension, but road bikes haven't changed all that much. Other than integrating the shifters into the brake levers (Shimano's version was introduced in 1990, 24 years ago), I don't think there's been too many significant changes.

comment Chain not fitting chain ring
I wasn't sure what was going on with the back wheel vis-a-vis the cog/cassette. If it has the original 7 speed freewheel/cassette it's definitely easier to just exchange the chaining for a 3/32 one. If however if you plan to do a full single speed conversion, it's probably a good idea to use 1/8 inch drive train components as they will last a little longer.

@andy256 I'd love to have n+1, but I think I'm getting close to s-1.

comment Tyre Rubber Classifications
I'm with @DanielRHicks on this one. When you're spending $6000 on a bike they have to come up with a whole lot of reasons the bike is actually worth that much. If you're spending that much on the bike, you should really be making your own tire decisions based on your riding style, and not have your decision made by the manufacturer/factory. In fact, you should probably have a few different sets of tires to deal with different riding conditions.

comment Is it ok to mix 23 and 25 tyres
No problems that I'm aware of. I use a 32 on the back with a 28 in the front.

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.
