comment How To Prevent Holes Around The Inner-tube Valve?
Then probably either the tubes are bad or the rim is the problem. (Though how close to the stem are the holes? Just a MM or two, or farther?) (And can we safely assume that you're not getting the tube twisted when you install it?)

comment How To Prevent Holes Around The Inner-tube Valve?
We need a few details. Are you using tubes with threaded stems, and using the nuts on them? Are you perhaps overtightening the nuts? (They should only be finger-tight.) Are you riding with the tubes under-inflated? (Should generally have at least 90 pounds, maybe as much as 120 in a tube that size.) What do you use to inflate the tires, and how do you measure the pressure?

comment What physically makes chainrings have a specific speed compatibility?
Yep, and consider the dynamics. Have you ever watched a rear derailer shift at high speed? The chain "dances". (It's really quite artistic.) Yes, it can probably be modeled, but even if it can and were worthwhile for the component designers to do so, the parameters would still be inaccessible to you and me.

comment How can a beginner cyclist build up power?
Just ride. Find some rides (and a general riding style) you like. Start easy, and have a "purpose" (like a trip to the ice-cream store. ;)) Don't worry about a "formula" unless and until you decide to become Spandex-clad bike nerd. But do get/keep the bike "tuned up", and have someone (a helpful bike shop or just a friend who's into cycling) help you adjust the bike to fit you.

comment Huffy Cranbrook 26“ Ladies' Cruiser crank / pedal / chain ”pop" sound…?
One possibility, for a one-piece crank: The crank turns the chainring (at least on the old one-piece cranks I'm familiar with) primarily via a pin from one crank arm that sticks through a hole in the chainring. If the whole assembly is loose the chainring could be flopping around as it turns, banging against the pin and the crank shaft.

comment What physically makes chainrings have a specific speed compatibility?
It's possible. But there's a certain "art" to the whole indexed shifting thing, and making it work smoothly. I'm sure hardly any dimension (other than the basic cog profile) is a product of pure mathematics, but rather they've all been "artistically" fudged until they work. For instance, as the chain rides up on the grooves it will twist slightly, and thinner chains will likely twist more. Compensating for the twist would be a part of the "art".

comment Huffy Cranbrook 26“ Ladies' Cruiser crank / pedal / chain ”pop" sound…?
Can you tell where the noise is coming from? Do you feel anything in the pedal when it happens? Could be a bad pedal, could be a crank bearing, could be the chain hanging on a chainring tooth. At least you know it's not a loose crank arm since the bike has a 1-piece crank. Grab a crank arm and give it a good shake. You should feel no looseness. If it feels loose the bearings may need adjustment.

That's a good article!

comment Stop my front brake lever screws from vibrating out?
There are several "flavors" of Loctite, including an "adjustable" variety. This may be hard to find, but an auto parts place or well-stocked hardware store may have it. Or you could use an adhesive that doesn't fully harden. (And rather than doing "tick tick tick", call out "On your left!" or "Passing!" -- much more effective, and easier on the hardware.)

Don't know why I didn't think to just Google John Forrester to begin with: johnforester.com/Articles/Facilities/TransQuart01.htm

comment New chain is pre-lubricated, should I clean it?
I think that, because chain wax is fairly soft, people often misperceive it as "sticky". It is a superior lubricant to most "chain oils", and is not particularly apt to attract dirt. If the coating seems excessive wipe the chain lightly with a solvent-moistened rag.

comment What should I be doing a week before a long distance bike ride?
Here's a small hint: A major portion of butt soreness in riding is not due to the pressure but due to the hairs being pulled out of your butt while riding. The common practice of riding a lot to get your butt "conditioned" is, in large part, a matter of getting all those hairs pulled in advance. You can "cheat" by shaving your butt (especially in the area near where the cheeks meet) a day or three in advance of the ride. (Be sure to to it enough in advance to recover from any razor burn.) Of course, this is more an issue for men, but many women have a non-trivial amount of fine hair there.

comment What should I be doing a week before a long distance bike ride?
While doing 80% would be ideal (well, 120% would be ideal, but 80% is close), it's not really necessary. I've seen people who've never ridden more that 10-20 miles do OK on week-long rides. Yes, your butt will be sore, but taking frequent breaks helps alleviate that.

comment Cube Scape seat creaking
On the off chance that the creak is coming from the rail/base connections you could put a drop of silicone oil in each. Not much you can do if the creak is between the layers of the seat, other than to get a different brand.
