comment Schwinn Spirit Trailer - Bearing Repair
Back when I had a bike with cartridge bearings I had a tool designed to assist bearing removal. It was a "bobby pin" spring with two metal semicircles attached to the two ends. You'd squeeze it and insert into the bearing, then use a drift punch from the other side to drive the bearing out. The above setup appears to be identical to what I had.

comment Rim brake pad interchangeability?
@ebrohman -- ??? There really is only one place for the shaft to be. Yes, it can be off-center or not (it isn't in this case), but that doesn't greatly affect braking performance.

comment Rear wheel noise
I suspect the noise is coming from your hub, and only occurs when it's freewheeling. If so, and the noise is not too loud, it's probably not a problem.

comment How to install bicycle pedals without a notch on the spindle?
Look at the threaded ends. There's a hex-shaped hole there, designed for an Allen wrench.

comment If chain/ BB/ casette are dead can chainrings and derailleurs still be OK?
The chain has gone about twice it's expected life at 11,000 km (6800 miles), and the rear sprockets are likely dead at that distance too, if not because of simple wear then because of being run with a worn-out chain. This is to be expected. Normally a set of front rings is good for maybe twice the 11,000 km, though being run with a worn-out chain will have increased the wear rate. The only parts that really wear on the derailers are the jockey wheels on the rear, but those are generally good for a long time. A better bike shop will have a gauge for checking sprocket wear.

comment Should I be continually weighting the handlebars?
It depends on the bike, the rider, the adjustments of the bike, and the riding style.

(If you've had this problem "several times" then you're doing something wrong.)

Stupid question: How do you know your gauge is parallel to the axle?

comment Flat tires every morning
I should mention that there are a few exotic brands of "racing" tubes which are ultra-thin and leak down in about 24 hours. You normally wouldn't have these unless you'd intentionally installed them (though perhaps without knowing the problems they'd cause), but it's vaguely possible that the bike shop sold you a "racer's upgrade" or some such that includes them. (But the simple "slow leak" problem described by others is far more likely.)

comment Why/how did flat bars take over?
Yeah, I noticed the bars getting lower and lower starting maybe 20 years ago. I strongly suspect it's because a bike with a lower (drop) bar looks "meaner" on the salesfloor, and hence is easier to sell to someone who has more testosterone than common sense. This was not a super big problem back in the days of quill stems, but with threadless headsets it's a lot harder to raise the bar to any substantial degree. The result is that the bike gets ridden twice and set aside, which is a shame (and a crime on the part of the bike vendors).

comment Need new 27x1 1/4 (32x630) tires, would the ones stated ONLY as 27x1 1/4 (without the 32x630 specification) fit?
All 27 inch tires are the same diameter, except for "27 five" ones. However, note that any tire made in the past 10-15 years will carry the ISO sizing on the sidewall, in addition to the "traditional" size.

comment How many spokes can break before I need a new wheel?
Once one spoke has broken that puts others under more stress. But certain types of spokes on certain wheels are prone to breakage, especially with age. If the spokes are cheap cad plated ones, vs stainless, then corrosion will get to them in a few years, even if there are not that many miles on the bike. Others, due to the design of the hub and spokes, will begin to fail after a certain number of miles. But a few spokes just fail randomly, and the wheel will be fine after they're replaced. A skilled eye can tell which, but there's no way to describe it.

comment My rear wheel isn't properly spinning. How can I tell whats wrong?
If there are broken spokes on the wheel then that is the first issue to deal with. The wheel will wobble badly until the spokes are replaced and the wheel is "trued". Of course, there may be other problems with the wheel as well, but we can't see enough from here to tell. But no way the wheel will work (for very long) with three broken spokes.

comment Trouble with spiral folding bike lock - jammed
The thing is that you need a lube that will soak into the lock, and not leave a residue. Not simply to preserve the lock for the future, but to get the stuck parts sliding.

comment Trouble with spiral folding bike lock - jammed
I would avoid the WD-40 and find a lock-specific lubricant, from a locksmith or hardware store.

comment Is there a “conventional” configuration for mounted accessories?
You can use a Velcro strap to secure the pump under the top tube. There is a strap specially made for this duty (though such specialization is not really necessary).

comment What is the minimum repair kit/parts I should bring on a 150 mile bikepacking trip?
On the GAP I wouldn't recommend burying anything -- use the trash cans. Soiled wipes should be kept out of flush toilets but can be placed in most porta-potties and the like with a clear conscience.
