comment Tube constantly getting punctured near the valve
I have heard of cyclists in Alaska having trouble with the tires spinning on the rims at -10F and below. But at those temps you don't even need air in the tire.

comment How can one estimate drag for a bicycle?
One could also, using a long rope (to avoid "drafting" effects), tow the bike and cyclist at a constant speed on level ground, with a spring scale between rope and cycle to measure applied force (which would equal drag). A little hazardous, but probably not incredibly unsafe if reasonable precautions are taken (including having a quick/easy way for the cyclist to release the tow rope).

Actually, applying a preparation intended for rubber V-belts might be a good solution to the "old rubber" problem. Several options are available from a hardware store or auto parts place.

Of course, in terms of the punctures it would be wise to examine the rim in the area of the stem hole and check for sharp edges.

comment What are the disadvantages of “puncture proof” (or puncture resistant) tires?
You confuse Kevlar bead with Kevlar belted -- you can have one without the other. Kevlar beads are used in "folding tires", and can indeed be harder to mount (especially the first time). But you can get Kevlar belted tires with a standard metal bead, and they are no more difficult to mount/dismount than a standard tire of the same size. And a "Quick Stick" will allow you to dismount/mount virtually all tires (except exceptionally narrow ones) with essentially zero chance of pinching/puncturing the tube.

Again, BS. "Rotating mass" is a red herring -- it doesn't slow you down any more than a non-rotating mass, and only slightly hinders acceleration.

comment What are the disadvantages of “puncture proof” (or puncture resistant) tires?
I don't know how this answer ever got upvoted so much -- it's pure BS. A good "puncture resistant" tire is simply a tire with a Kevlar belt, and is not noticeably heaver than a standard tire. And they are an order of magnitude more puncture-resistant than their un-belted brethren.

Are you both standing on the pedals when this happens?

comment What causes the threads on bike pedals to become stripped?
There is one other slight possibility -- that somehow old French pedals were installed in a bike with "standard" pedal threads. The French pedals have threads with a slightly smaller diameter.

comment Why do my brakes squeak? Do I have an incorrect distance between brake pads and rims?
Question -- When you brake do the brake levers squeeze all the way down to the handlebar, or is there still some space under them. It sounds like perhaps you're simply not able to squeeze tight enough, due to cable slack. (Note that if the wheels do not maintain a constant distance from the pads you need to get the wheels trued.)
