Old, tired, crazy.

comment Are the country roads quieter on weekdays or weekends?
I would say the same as what Chris H said for the US. Traffic on a given road can change by a factor of 10 within 15 minutes, when schools let out, a distant factory shift changes, it's simply lunch time, etc.

comment How much does tire pressure affect the weight of the wheels
@RossMillikan - I was being facetious. A value within a factor of 10 is good enough here.

comment Getting back on the bike after bad fall, how do I get over my fear?
Critical question: Were you mountain biking because you enjoyed it or because your BF wanted you to?

comment When riding with a single pannier, does it matter which side it's on?
In my opinion it makes no difference. Since I tend to dismount on the right side, I usually use the right pannier if using only one, since that's quicker to access. And if you lean the bike or put it in a rack somewhere, one side may work out better than the other.

comment What is a cheap puncture-proof tire against tackweed?
Yeah, Kevlar belted is probably your best bet. Unfortunately, they're a little hard to find in such a wide size, and the wider they are the more expensive they are. Continental Gatorskins in a 32mm are $45. The other major puncture-resistant design uses a fairly thick plastic belt under the tread which may be as effective as Kevlar but adds rolling resistance.

comment Can I approximate how much air pressure is lost from disconnecting the hose?
The air in the hose is irrelevant. It's the amount of air that sneaks past the tire valve before it snaps shut that is the issue. And this is in large part a matter of technique.

Well now, is it 7.56g or 7 even?? You guys make up your mind!!!

comment How much does rider weight increase tire pressure?
Consider: If you had an infinitely large tire (or at least a very large one) pumped up to 50 psi, with 50 pounds of weight on the tire there will be 1 square inch of contact. Add another 50 pounds and the contact patch increases to 2 square inches. Has the pressure in the tire doubled? No, the increase in contact area "bears" all the added weight and the pressure doesn't go up at all.

comment How much does rider weight increase tire pressure?
No, the charts from Cole are not measuring pressure increase, but simply indicated "suggested" pressure for a given weight.

comment What are the Pros/Cons of a 2.1 vs 2.3 wide Mountain Bike Tire
The difference isn't enough to worry about.

comment How much does rider weight increase tire pressure?
The "spot" the tire makes on the pavement must grow from essentially nothing to an area sufficient to counteract the weight of the rider. But the tire pressure does not need to increase much to accomplish this, especially at 100 psi. Exactly how much the pressure increases could probably be (approximately) calculated but the math would involve the volume of a torus, etc, stuff I wouldn't touch (especially since I'm on vacation for the next two weeks).

Wear glasses for 60 years and you'll learn how to ignore it.

comment Single pivot brake with handlebar levers (Resurrecting an old Colnago)
The problem you run into is "pull" -- how far the cable moves from it's initial point until brakes are fully applied. V-brakes require roughly twice as much "pull" as most other styles, and hence V-brake levers are designed to pull twice as much cable. As a result, on regular brakes they will feel stiff and will not allow you to apply very much force. You really should find some non-V-brake levers.

comment Are there sirens/horns that are like a car horn?
I also found this unit that is purpose-made for bikes and you refill with a bike pump.

comment Are there sirens/horns that are like a car horn?
I think the only reasonably light and compact alternative is one of the compressed air horns. If you can't find a bike version there are units sold for small watercraft. Eg: gandermountain.com/modperl/product/…

comment My bike after a new spray paint, gets scratched easily
This is what paint does. Depends a lot on the quality of the paint, but pretty much all spray-can paint is pretty soft. It does, however, harden over time -- so after maybe 3 weeks it should be harder than after the first few days. But if the paint and primer are coming off and leaving bare metal you probably used the wrong primer, or applied it incorrectly.

comment Is it bad etiquette to ride road bike through a small residential area?
Do be aware that in some localities there are "gated communities" where "thru traffic" of any sort is regarded as trespass. But this is because the streets are considered private property, not public roads. (And there would have to be adequate signage on entry to the area to let you know this.)

comment Minimum mountain bike trekking/touring equipment
For sleeping (I don't mountain bike, but have done self-contained touring and still pretend to at times), I recommend a compact inflatable sleeping pad (Therm-a-rest). There are "half-size" and "3-quarter" size units that are small and light. (I use a 3-quarter.) On top, a bag suitable to the weather -- down is nice but not good when wet, several synthetics are nearly as good but don't pack as compactly. Tents span quite a range from nothing to bivy sacks to compact mountaineering units to palaces. Unfortunately the old Gerry Mosquito hasn't been made in 30 years, though - it was perfect.

Some sort of tire "boot" is probably a good idea. And rather than/in addition to duct tape I recommend "hockey tape".

comment difference between rack mounts and fender mounts?
Sometimes the same single set of eyelets may need to be used for both purposes. And when the eyelets are doubled up there's no obvious difference in the robustness of one set vs the other. I've never heard of the eyelets failing.
