comment Should tyre sidewalls appear cracked so quickly?
You should get a decent "floor pump" with a gauge, and check the tires at least once a week, more often if they tend to "leak down" fast. A frame pump is good to have but you can rarely get the tires up to proper pressure with one. For normal urban commuting you should be running at least 50 psi, probably 75 or so, depending on the specific tire.

It sounds like they've been ridden with too little pressure. How much pressure do you run?

comment Why did the hydraulic disc brake stop working when riding down a steep mountain?
If there had been air in the line the levers would have gone "mushy" rather than simply having no resistance at all.

comment Why did the hydraulic disc brake stop working when riding down a steep mountain?
Likely a combination of the brake fluid boiling and simple leakage past the brake lever piston as pressure is constantly applied. When you "pumped" the lever that pumped new fluid into the system. The same phenomenon occurs with auto brakes. You likely exacerbated the problem by constantly "riding" the brakes vs using them in intermittent "bursts".

comment Sudden tyre deflation with no puncture
What type of valve? And did the tire go completely flat, or just lose some pressure suddenly?

Yeah, I'd especially like to have solid gold spokes.

+1, though it would have been better if you asked the question on a Friday afternoon.

comment Loose pedals on Norco MTB
The pedal shaft should be very rigidly attached to the crank arm, and the crank arm should be very rigidly attached to the crank shaft. If there's any "play" it should only be in either the pedal bearings or the crankshaft bearings. (If there is play where the crank arm attaches to the crank shaft then that's an "emergency" and needs to be remedied ASAP.)

comment chain getting stuck between chainrings
I ran into a guy who had this problem fairly often. The bike was an old one and had a new rear cluster and narrower chain to match, so the chain would get stuck between the front rings. Easiest way to get it out, as I showed him, was to slightly loosen the top-most chainring bolt. Probably the correct fix would be to install narrower spacers.

comment Converting a Bicycle without gears into a Geared one?
Probably not. You might be able to install a multi-speed hub, but they're fairly expensive.

comment Theft deterrents (in addition to locking up a bike)
Not really a theft deterrent, but I have a gummed label (covered with clear tape) with my name, phone, and emergency contact info glued to the top tube. If the bike is just "borrowed" and abandoned there's some chance I'd get it back, plus if I'm ever in an accident the label is visible enough that emergency personnel would likely see it.

comment Do these pads look contaminated?
Yeah, if the new pads don't help much you can just keep the old pair as a spare.

Replace them and see if that fixes your problems.

comment Is it appropriate to build bikepaths in local roads instead of Minor or Major Arteries?
I'd say this is entirely a matter of preference and politics.

comment Chain brushes derailleur
BTW, I think my experience with "clipless" pedals was about typical -- two falls in the first two days due to them, then none in the next ten years.

comment How do I train for climbing in a relatively flat area?
I vaguely recall seeing, in a cycling magazine maybe 30 years ago, a setup that consisted of a second set of brakes that could be set to exert a constant drag, for training purposes. Would, of course, wear out your brake parts quite rapidly.

comment What U-lock has a reasonable weight to safety ratio?
This depends entirely on where you live/work and what the risks are. Around here I only use a lock (aircraft cable and padlock) because it gives me peace of mind -- I see unlocked bikes all the time, and thefts are rare. Other places you need a 50-pound anchor chain to be even halfway safe.
