comment Should a saddle hurt?
An important point: In the same general area of the anatomy that contacts the seat of a bicycle are muscles that are rarely used except in certain activities (such as cycling). If someone is not at all acclimated to cycling (and doesn't do a lot of other activities such as stair climbing) those muscles will be sore 12-24 hours after a moderate amount of cycling. This is to be expected, and will quickly correct itself with even modestly regular cycling.

comment Should a saddle hurt?
Some discomfort is normal, until your anterior "toughens up" a bit. But if the seat is painful pretty much from the start then probably something needs to be changed. Painful the next day is a bit more "normal", though if it continues the seat may need attention.

comment Which usually wears faster - wheel rims or brake blocks?
The chain should be replaced when it's stretched, the cassette and rings when they're worn. If you service each appropriately you will get maybe 2-3 chains per cassette and 2-3 cassettes per large ring. (But if you replace a cassette you should usually replace the chain at the same time.) And you should be able to get several standard brake block sets per rim.

comment Choosing a handlebar width
In addition to what the others say, slightly wider bars tend to be more comfortable on long rides. And narrower bars, of course, slightly reduce your wind resistance.

comment How to build surge brakes on bike trailer?
Do the math -- Decelerating at so many feet/second squared will generate so many pounds of force. Compare that to the force needed to squeeze your brake lever to a suitable pressure, then figure out what the actual cable pull is.

comment How to build surge brakes on bike trailer?
Clearly one could build a surge brake for a bike trailer. Probably a cable system would be most practical. But given the usual light weight of a bike trailer you would need substantial "travel" (probably 2-4 inches) to apply enough brake force, meaning you need a lever or pulleys to convert the motion to the shorter, more forceful motion needed to drive standard rim brakes.

comment What brand is this vintage bicycle?
I would think that if it were branded for TWA airlines the badges would resemble TWA's logo a bit more. This image shows several logos, and there is no great resemblance. (However, a plausible reason for there being TWA airline bikes of about that style would be for transportation around airports, though one would expect a basket.)

Why was the chain replaced?

comment How long should brake pads last?
It's all over the map. I get several thousand miles from my brake pads, others get a few hundred. However, it's extremely unlikely that someone could wear out a set of pads in 50 or so miles, unless the brakes were badly misadjusted from the start or the rider was intentionally riding with the brakes on.

comment Does a high MTB seat post risk frame breaking
I often wonder about some of the bikes I see, especially BSOs with long seat posts. But I don't recall seeing any reports of seat post/tube failures.

comment Right crank (Drive side) on the left?
If you leave the sprockets on it may interfere with the frame, since the right-side crank shaft is often longer than the left.

comment Tips for winter maintenance?
That's more than a couple, but a fair list. One should go easy on WD-40, if you use it at all, since it will tend to wash away lube.

comment Tips for winter maintenance?
It should not be necessary to rinse unless there is salt on the road, and even then one needs to be careful to never direct water spray into bearings. I find it strange that your hubs "got hammered" unless you were spraying water into them.

comment Is an old mtb with replaced gear safe to buy?
The concern with the front wheel "replaced due to hitting a stump" would be that the fork was damaged or (in extreme cases) the frame was bent. The leakage reenforces the suspicion of fork damage. But there's certainly nothing wrong with having cables replaced -- that's necessary on bikes every 10K miles/10 years or so and is simply a "scheduled maintenance" sort of thing.

comment Why are brake lights not common?
This is a valid point. A) Bikes are rarely going that fast, especially in traffic -- the "delta" velocity between moving and stopped is small. B) Most cyclists are very aware of vehicles behind them when cycling in traffic, and very wary of making sudden moves. And when riding in a draft line one gets better info by observing the feet of the cyclist ahead.

comment Why are brake lights not common?
There may be a change, now that hydraulic brakes are more common, since they make adding a light switch much simpler and more reliable. Previously, getting a switch to work on a cable-operated system was bulky, heavy, and unreliable. Plus the point about not having bright LEDs.

comment Cyclocross touring, studs for SPD shoes?
Studs are a bad idea if you might need to do any walking. Using SPD cleats, on the other hand, is a good idea.

comment Prevent xtracycle hooptie rattling noise
I would guess that the rattle is from the "hoops", if nothing else is loose. I suggest somehow securing those -- several wraps of electrical tape at the junctions between the segments should do it.

comment Medium size cargo solution for road-bike for commuting
I would suggest a lightweight rack and two smaller panniers vs one large one.

comment My back wheel isn't connected to the gears
Yeah, you need to take it to a bike shop, unless you're a lot more mechanically inclined than you seem. It takes some special tools and may require some parts. Hard to say how expensive, but the shop should be able to give you an estimate after looking at it for a couple of minutes, since the basic problem will be pretty obvious.
