comment How do I properly adjust a front derailleur?
@CareyGregory -- If a derailer "springs out" the cable will be pulling it in, and you'll notice as you adjust towards the larger ring that the cable feeds towards the derailer and becomes more slack. And, with the cable removed or totally slack the "springs out" derailer will be positioned more or less over the large ring.

comment Why choose a traditional frame over an aerodynamically streamlined frame?
Like I said, the wheel-hugging seat tube WOULD have an effect. "Aero" shaped tubes, no. And in this test there's a strong chance of a placebo effect -- in fact, in the first trial the rider averaged (roughly calculating) 96 watts, while in the second case he averaged 127. You tend to go faster when you expend more energy.

comment Why choose a traditional frame over an aerodynamically streamlined frame?
@R.Chung -- OK, I should have said "significant" rather than "measurable". I can't see how streamlined tubes would reduce the drag of bike and rider by even 1%, and that advantage would disappear under real-world conditions.

comment Why choose a traditional frame over an aerodynamically streamlined frame?
@KenHiatt -- I have my doubts. The turbulence from the front wheel destroys any "streamlining" advantage for the down tube, and the cyclist's legs would likely do the same for the seat tube. There may be a slight advantage to the curved seat tube of the S5 above, the way it hugs the rear wheel, but that would be the major part of it.

Or, best of all, a "Quick Stick". Faster than tire "irons" and less likely to damage the tube.

I strongly suspect that "streamlined" frames do not provide measurable improvement over standard round frames. They exist mostly for looks. And they likely weight a hair more and make it harder to add things like a strap-on water bottle holder.

comment Should I fight a ticket I got for riding my bicycle in a crosswalk?
If there was a push-button and you pushed it and the light didn't change, or the light is timed and never gave you a "walk", you can argue that the light was malfunctioning. Generally the law allows you to "proceed with caution" against the light if the light is not functioning properly. But different states have different rules about how long you must wait, etc.

comment Should I fight a ticket I got for riding my bicycle in a crosswalk?
You need to check your local laws. In many cases bikes are not allowed on sidewalks. I generally walk my bike across intersections if I find I must use the "sidewalk" crossing. Walking your bike you're a pedestrian and have right-of-way so long as you didn't start across against a light. (The "notice to appear in court" is fairly standard in many cases. If you don't want to contest the citation you can generally pay off the fine before the court date.)

comment Can your rims wear down from too much braking?
One thing you can do to help reduce wear is to squeeze and release the brakes several times (vs simply steadily squeezing) when first stopping after riding through grimy conditions. This helps clean off the grime with minimal scoring of the rims.

comment Spokes keep breaking - bad hub or bad build?
@RasmusRask - Well, the countersink isn't usually dramatic. And unfortunately I can't find an image on the web that would show the holes.

comment How do I use retro drop down handlebars with no hoods?
The first thing to do is to rotate the bar upward so the top is flatter.

comment How fast does new technology “trickle down” to lower models?
I really question to what extent "quality" is better on higher-priced models. The manufacturers will tend to use the same manufacturing line for all versions of their parts, with the main difference being finish -- maybe they tumble the diecastings before finishing, maybe they color-stain the machined aluminum, maybe they add a colored washer. Of course, there will be a difference between a steel frame and a carbon one, but likely the derailers are the same quality, with only finish differences.

Too fast, in my opinion. Most "new technology" in cycling is more for show than function (and more to produce sales than to provide value). And kids buying department store bikes are attracted to the bling.

comment Why is my front Derailleur not shifting as smooth as it used to?
It should be noted that if the cables have stretched out this much it may be time to consider replacing them.

comment How do you shift your weight when leaning on a turn?
@StephenTouset (And, in fact, you can't "maximize" traction by shifting your weight. The angle of thrust (relative to the road surface) will be the same for a given speed on a given turn, regardless of whether your body is leaning left or right. There is a slight difference in tire traction depending on whether the tire is upright or tilted, but probably traction is slightly better with the tire more upright.)

comment How do you shift your weight when leaning on a turn?
@StephenTouset -- Slipperiness matters quite a bit. As I said, he never appeared to be close to losing traction, on dry, smooth pavement, so there was no need to "maximize traction". But riding on a wet, slightly oily, slightly muddy country road and trying to make a relatively tight (and unbanked) turn puts you very near "the edge".
