comment How to dress for biking 3 miles to work in 40 and below so not to sweat to much but still keep warm
I used to commute to work 10 miles each way (25 when I took a "short cut" some mornings). This in southern MN (near Rochester). Down to 45-50 I'd generally wear T-shirt and running shorts. Below that I'd slip on a pair of sweatpants and a sweatshirt -- easily removed (and shoved in my pannier) when I warmed up and needed to be cooler. For temps below 30 or so I had wind pants & jacket. Would commute down to about zero. (I don't commute any more after I changed jobs and it became less convenient.)

comment How often should the headset be tightened?
I've seen headsets that were remarkably loose. Though looseness affects handling to a degree, most people don't notice the problem until (in the old threaded headsets) it gets so loose the ball bearings fall out. (Obviously, since it's so easy to check one should check a few times a year. But no real "schedule" is needed.)

comment Derailleur twitching in low gears
You might want to invest in a spoke guard. They are considered vulgar by purists, but they can save your derailer, and can also prevent a bad spill.

comment How often should the headset be tightened?
About once every 10 years. At least that's about the average for most bikes. (To check your headset, sit on the bike, lock the front brakes, and push forward/backward with your feet. If you can see any looseness in the headset it needs to be tightened.)

comment Is it preferable to pedal downhill?
The "more momentum for the coming uphill" argument is pretty weak. The rate at which you lose energy to air resistance quite high, so only the last few seconds of pedaling effort on the downhill is likely to "carry over" (and that only if there is no significant level section between).

comment Should one pedal over a mild slope?
Yeah, if the downhill slope is sufficient to maintain, say, 15 mph without pedaling then you're probably better off putting most of your energy into maintaining a good aero position rather than trying to pedal faster.

comment Do good tires lessen the chances of your innertube bursting?
And as Carson's question suggests, where on the tube the "burst" occurs can tell you a lot. If it's on the part that presses against the rim them likely there's a hole in your rim strip (or the rim strip is missing entirely). If it's in the area of the tread then likely there's a hole (cut) in the tire. If the tube bursts near the junction between rim and tire then it's likely that the tire is slipping off the rim.

comment How much should the front wheel flex
It should be noted that disk brake front wheels, due to the asymmetrical spoke arrangement, are apt to flex more than rim brake wheels.

comment Should one pedal over a mild slope?
In terms of "conservation of energy" you're better off just coasting, and if you were in an endurance event coasting would be the way to go. But you're apparently not, so do whatever works for you.

comment Do good tires lessen the chances of your innertube bursting?
An innertube of even mediocre quality does not "just burst". There must be a "discontinuity" in the "envelope" around it (the rim and tire) that leaves a bit of the tube without support such that it balloons out. Sometimes this is a missing rim strip, sometimes it's a hole in the tire, sometimes it's the tire slipping off the rim.

comment Behring custom made bike
No hits in Google. It could be a small frame builder -- there were quite a few a few decades back, when a 10-speed would have been built. Most have unfortunately disappeared due to Chinese competition and the current infatuation with exotic materials.

comment Do DC HUB Motors For Electric Bikes use regenerative braking?
I don't believe they do. What would be needed would be a sensor in the brake levers that measured brake force, and I believe that the most they have there is a cutoff switch. But there are a lot of different schemes.

comment Kenda cyclo cross 27 x 1 3/8 fit on 27 x 1 1/4 rim?
Back when I was running 27" tires it was common to swap tire widths, within reason, and I don't recall anyone ever having problems. According to Sheldon, all 27" tires should be 630 rims.

comment Can I use WD-40 on my bike?
Yes. While I feel there are uses for WD-40 on a bike (good for cleaning gunked derailers, eg), it's a lousy chain lube. And a decent chain washer is a far better way to clean the chain.

Did you look in your owner's manual to see if there's a wiring diagram?

comment Choosing New Rims/Hubs & Assessing Size
Confusing: 559 is the ISO size for 26" wheels. But if it's fitted with 700c tires (and they appear to fit right), that's the way to go. As to a new wheel, you might actually do best at your LBS -- they usually carry some inexpensive replacement wheels (at least in the US), and you don't need to pay shipping.

comment Broken glass on the bicycle path, what to do?
One thing to do is to look/listen/feel for bits of glass that have stuck to the tire, and if you sense them stop and brush off the tires.

comment How do you make an end-capped gear cable?
(A common trick is two beads. You put both beads on the cable, then bend the cable around and fish the end back through the bead placed on the cable first. Pull tight and you have a fairly strong lock. Similar things are done with small metal plates with holes in them.)

comment My front wheel was steering to the right… now it's steering to the left. What's the cause of this?
Define "steers to the left". Do you mean when you take your hands off the handlebar? Does it happen only when pedaling or when you're coasting and relatively "neutral" in body posture?

comment Adjusting air pressure in the Tyre /Tire
(And, of course, for road efficiency you want tires that are nearly treadless.)
