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.

Actually, dogs, being used to lots of people here, are less apt to be a problem than in a more rural setting.

comment Is it bad etiquette to ride road bike through a small residential area?
Certainly not bad for a single cyclist (or a handful) when there's light traffic and not hazard to children, etc. Running RAGBRAI through there, OTHO, probably wouldn't be appreciated. (And I suspect that some folks might actually get a kick out of seeing cyclists here.)

comment How can I mount a 25.4 mm seat-post on a frame that needs a 27.2 mm seat-post
Yes, the important thing is that the shim go most of the way around the post, vs just being on one side. And having a "lip" at one end (as the commercial ones will have) keeps it from getting lost in the seat tube. (Aluminum beverage cans are a good source of shim material.)

comment How to replace old style cotter-pin bottom bracket with a modern one?
Yeah, the trick is to find the right BB bearing assembly, that is the right overall diameter and length and with the right threads on the cups. If you possibly can fit one in, a cartridge unit is better than loose bearings, but some of the old BB shells were pretty small diameter.

comment 1980's bike vs New(er) Models? (Should one stay with an ancient bike?)
Yeah, looking around it appears that about $700 ("list") is the starting point for a decent road/touring bike. Of course you can always try to bargain -- I'd bet some shops will come down $50 or maybe even $100 if you have cash in hand.

The selection is better in the spring, but (at least in the US) the prices are MUCH better in the fall -- 30-50% lower in some cases.

comment How do I remove a bottom bracket?
Yeah, place you're fingernail in the groove of the cup and "unscrew" your hand. Whichever way "unscrews" vs going tighter is the direction you need to turn the cup. That appears to me to be a "normal" right-hand thread that will unscrew in a counter-clockwise direction, but it's hard to tell for sure in a picture. Definitely use a wrench with good square jaws, since if you muck up the shoulders of the "nut" it's a lot harder to get it loose. A well-equipped bike shop might have a flat wrench to fit.

comment How bad is this fire damaged alloy frame?
If there is going to be a problem with the frame it would most likely develop where the top tube joins the seat tube or the head tube. If you regularly inspect these areas for cracks for the first several hundred miles (avoid applying heavy paint to the areas) then you should be OK. (I think the folks on that other forum were overreacting a bit.)

The headset bearings are almost certainly cooked and need to be removed and cleaned/relubed or replaced.

Weird fire. Didn't touch the tires??

comment 1980's bike vs New(er) Models? (Should one stay with an ancient bike?)
There are only two reasons to abandon an old bike: 1) You can no longer (at a reasonable price) get replacement parts for it. 2) It no longer suits your needs. It sounds like #2 may be a problem for you. However, $500 is pretty tight for a budget if you're shopping in the US at this time of year (you can usually get some nice deals in the fall). You might want to look at Craig's List, et al, for a good used bike that suits your needs.

comment remove “wrench force” floor bike pump from the schrader valve
It sounds like you have a defective chuck. (One thing to note, however, is that some chucks lock by flipping up the lever, others lock by pressing it down. It may be that you're inflating with the chuck unlocked and then trying to pull it off locked.)
