comment What is the minimum repair kit/parts I should bring on a 150 mile bikepacking trip?
Yeah, it's critical to have adequate sun lotion (and use it before you notice you need it), and having some bug repellent is helpful too. Last year I had along a bunch of "Off" brand "Deep Woods Towelettes", which are individual wipes, saturated with bug repellent and sealed in individual packets. One of these could be stretched to "treat" 3-4 people at a stop, and my companions were delighted to get the left-overs after I'd used one on myself.

comment Diagnose grinding sound from single rear cog
It's hard to say. The old 10-speeds tend to be a bit more tolerant of the cog wear problem than newer ones. And if it can't handle the new chain you can try removing one link pair from the old one to shorten it (if it appears that chain length is the issue).

comment Where does the energy loss in cycling go proportionally?
It should be noted that rolling losses can increase significantly on rougher roads. Most of this energy, believe it or not, goes into jiggling the body up and down.

@SGR - Actually, the amount of energy going into cussing out the hill you see coming can get to be quite large.

comment I have a hybrid bike which the frame is too big, is there any modifications I can make to make it more comfortable?
You might consider installing smaller tires. The inner diameter of the tires must remain unchanged, but, for instance, going from a 2.5" wide tire to a 1.5" wide one will reduce the effective bike height a half inch.

(Also check the "related" column to your right for first aid kit suggestions. You don't need a lot, but a few bits can make a minor spill much less unpleasant.)

You should make sure that the hand pump is a decent one. Many "compact" pumps are more theoretical than practical -- you can get the pressure up to 20-30 pounds after 15 minutes of work, but forget about 50-70 psi. A full-length "frame pump" is by far the best choice over "compact" units.

Yeah, that's a pretty civilized part of the country, and, besides that, many other cyclists will be along to lend assistance if need be. The kit you have (plus the suggested minor additions) should be plenty. The only other thing to be sure to have is rain gear.

comment Diagnose grinding sound from single rear cog
One possibility is that, in certain cog configurations, the derailer jockey wheels are actually rubbing/bumping against the cogs. This would typically due to chain wear and a resulting chain that's a hair too long. (For a bike of that age it's just about a given that the chain is worn out and should have been replaced 10 years ago.)

comment What are my options for correcting a bent aluminum fork?
Yeah, I think it would be wise to disassemble the thing and figure out precisely what is bent.

comment Why are most BSOs mountain bikes?
I do have a gripe that drop bars are "pushed" a bit too hard, for the mid-range buyer. First off, the bars are installed too low (looks "meaner" on the floor), and (since quills went bye-bye) it's not easy to raise drop bar. And, while different-shaped drops are theoretically available, in practice you can't find them. Plus many mid-range buyers would be perfectly happy and well served with a flat bar.

comment Why are most BSOs mountain bikes?
Most BSOs are sold to kids (or their parents). They are not into road biking or commuting but rather into jumping curbs, riding up/down whatever hills they can find, etc. Plus the suspension and other whiz-bangs looks neat. You can buy BSO road bikes (I believe that Huffy still sells some) but you have to look around.

Is it possible that some dirt has gotten in there?

comment Shifter with stuck barrel adjuster
On some shifters of that style the adjuster has a spring and sort of ratchet mechanism in it, and you must pull the adjuster barrel out to turn it.

comment Is the real world experience of riding a light bike understated by physics-based calculators?
It needs to be noted that Joe's "aerobic threshold" may be 300 watts one day and 325 the next. The experiment you propose is not reproducible in real life.

Put them on Craig's list. (Or give them away, as suggested.)

comment Is it OK for a child's bike to have a radially-laced rear wheel?
(In my bike repair work I've never seen a 12-16 inch wheel that was damaged, other than due to being run over by a car or some such. It's fairly common to see a 20-24 inch wheel that is damaged, though, apparently from doing stunts. But these larger wheels, to my recollection, are always "properly" interlaced (and the damage is almost always to the front wheel, not the rear).)

Actually, they are diagonally laced, to a degree, just not crossed. The mere fact that the hubs are drilled with holes aligned vs offset produces a diagonal lacing. What you don't have is lacing that balances the "diagonality" on both sides -- the spokes are tugging forwards on one side and backwards on the other. (On a wheel so small, with spokes maybe 5" long, there's simply no room for "crossing".)
