comment Any experience about radially-laced hub flanges actually breaking?
Certainly there are now a lot of radially-laced front wheels in use, and there is not a flood of reports on their failure. And I've only read (from several "credible" sources) stories of this happening (the perforated separation) -- never experienced it personally or seen an hub damaged in this way. While I'm no big fan of radial lacing, I guess I'd say that this reason for avoiding the technique is not particularly high on the list.

comment Is it possible to glue or patch tire sidewalls?
Yeah, if it's the only way to get home you do it. But the dollar bill is a better choice.

comment Is a recreational bike sufficient for a 10-hour bike trip?
Yeah, it is a long trip. Definitely not a one-day trip for a novice (unless you're into self-abuse), but a fairly easy 2-day trip.

comment How can you speed a road-bike up?
Rotating mass and acceleration: This question shows that the rotating mass slows acceleration AT MOST 2x the same non-rotating mass would slow acceleration. So a change of rims that shaves 1 pound from the bike will be like shaving 2 pounds of non-rotating weight -- measurable in a lab, but not going to make any major difference.

I've used a tire patch for a large puncture, but would not trust it for a bruise or slit.

If you make your own boot, it should be cut from the sidewall of the old tire, and the tire should be one with relatively thin sidewalls. For the dollar bill, it should be folded once or twice.

comment What's the cheapest way to get into training with power?
Find some long hills of constant slope. Given your weight and power and the slope of the hill you can calculate a target speed, or vice-versa.

comment Are bicycle helmets repairable or disposable?
@MladenJablanović -- There are a few manufacturers who will replace a helmet for free after it's been visibly damaged in a crash.

comment Self-made studded tyre with glue?
The "old fashioned" way to make studded tires was to drive "sheet metal screws" through from the inside, then cover the screw heads with heavy tire liner.

comment Are today's bikes “better” than a few decades ago?
Yeah, I'd rate brifters as not quite a "major impovement" -- maybe a "captain".

comment Clicking handlebar
Well, the timing will obviously depend on the usage of the bike and particulars of its construction. And this creaking is largely limited to bars with a reenforcing sleeve at the center (which is usually but not always obvious).

comment Map during touring?
BarMap of the Gods is another similar map holder. It unfolds to display a (more or less) full page, and folds up to display a roughly 1/4 page map.

comment What's this? Photo of bicycle with pedals by the rear wheel
@dumbledad - Some tandems are set up with the cranks about 90 degrees out of sync. I believe there are several "theories" for why this is a good idea -- easier starting, more constant power, less wobble, etc. What you generally don't want is the cranks about 180 degrees apart.

comment What's this? Photo of bicycle with pedals by the rear wheel
@cmannett85 - Yep, looking at the photo yet again I see that you are right. The far-side chain angles down to a rear derailer, so that it's (barely) distinct from the "single-speed" chain on the near side. What's odd is the lack of clear provisions for a seat. There are bars on either side of the wheel but clearly insufficient to support a seat. But perhaps some additional hardware attaches.
