I'm a self-teaching geek. teaching because that process is far from over. I don't know a ton, but what I know, I'll share, and I won't answer a question if I'm not confident I'm correct.

comment Carbon bikes make me nervous. Can you ease the tension?
@Vorac: That is not accurate. They have a limited 2 year warranty on the Session (carbon) model frames and swing arms. All of their other carbon frames have a lifetime warranty. As to why, you'd need to ask Trek. But I suspect it has something to do with the way the Session is ridden. Being a freeride/DH machine, it's use is far outside "normal". By the way, the Aluminum Session listed has a 3 year warranty, not lifetime.

comment How much does non-ideal frame size matter?
...rider will tend to naturally reach farther than a less flexible rider, and will thus be more comfortable on a larger frame.

comment How much does non-ideal frame size matter?
As you noted, that is why a proper bike fit with a trained technician is important. :) For example, with my body (also 5'11"), a 56cm Scott or Specialized or Trek works well, but a 55cm Storck, a 55cm Bianchi, and a 52s Colnago C59 all fit pretty close to the same for me. Partly, that is a difference in how the bikes are measured, and also with the varying geometries used in their creation. Someone who is 5'11" with a long torso and shorter legs, may fit a 58cm better than a 56cm. Not on the "average" person, though. Even your flexibility can mean a change in frame size. A more flexible...

comment How much does non-ideal frame size matter?
This is a pretty good answer, although a 55/56cm frame for most people would fit closer to 5'11"-ish, and a 60cm frame closer 6'3"+, typically. Aside from that detail, which was already noted by @Batman as only an intuitive guess, +1

comment Clip-on to temporarily convert Look pedal to stand-on style?
As others have noted, the product actually looks like a good option, but the answer, as written, doesn't show that. Please edit your answer to show a bit more detail and encourage others to actually read it.:)

comment Why are 10 speed chains so expensive?
@Mac: Hypothesis does not, in fact, make a better factual answer than an assumption, since a hypothesis is only an assumption based on at best incomplete data used to BS a grant committee into funding the researcher's lifestyle while he does the research. :) It's the result of the research which would make a better factual answer.

comment Puncture resistant tires
They are heavy, and while they work well in the short term, they dry out and get brittle over time. Eventually, after around six months, they will get sharp enough to cause you flats.

comment What is the name of the part, often seen on BMX bicycles, that allows an additional rider on the back the bike?
@Erik, I'm not going to argue with you. If you know bikes, you know this is unsafe. If you don't, then you can say whatever you like. I will not respond to you further.

comment Can Garmin Edge 500/510 and 800/810 be charged while riding?
If plugged into a PC, it switches to disk mode, and will not function as a bike computer or GPS. If plugged in to a wall outlet, it will function just fine.

comment What is the name of the part, often seen on BMX bicycles, that allows an additional rider on the back the bike?
@Erik, I have been working in bike shops as a mechanic since 1992 to current. Most of our bikes in the shop, as of today are 14mm axles, at least on the rear. The front is more of a choice. The front axle isn't 10mm, it's 3/8" or 9.5mm. And the material properties of cro-moly and high carbon steel haven't changed, but thanks for your condescension.

comment Better 7-speed chain for Trek Allant?
While I appreciate Mr. Brown's take on many things, I'll stick with what Shimano says. Since they design and build the chains.

comment What is the name of the part, often seen on BMX bicycles, that allows an additional rider on the back the bike?
@Erik, yes, I have. I've also seen a number of axles which break for those reasons, also. Pros get paid to ride, and can afford to break both their bikes and there bodies. This is a primary reason why many axles were upgraded to 14mm from 9.5mm, back in about 1995.

comment How do I bring an old bike up to speed?
@sistyfootersdude: You are welcome to disagree. There are obvious benefits to restoring an older bike, most of which are educational. If the point is to have a decent, well functioning bike for the least cost available, though, replacing the bike is still the way to go. Not least because you rarely see all the problems up front on a rebuild, and thus have no real idea of what the final cost will be until it is done. If he wants to update the gears and rakes alone, as he suggested, that will cost more then th finished bike will be worth, unless it is solely for educational purposes.

comment How do on-road mountain bike speeds translate to road bike speeds?
@Kevin, yeah, I use it a lot. I kind of disagree that gearing is not a limiting factor, though. Even if you are not in your top gear all the time, the gearing is radically different throughout the range. I am including wheel size and tire dimension in the drivetrain and gearing. Obviously, fitness and rolling resistance, and bike weight and many other things play a part, but gearing is the largest mechanical differential between mountain and road bikes.

comment Can the Tensioner Spring go Bad on a Rear Derailleur?
It is a symptom of worn teeth on the drivetrain, bad chainline on the bike, or bent or broken teeth, or links in the chain. But given where you are describing an issue, and what you are describing, I would say that the pulleys are likely causing this particular issue. You should replace them. But you should also replace the rest of the cassette, and the chainrings.

comment Can the Tensioner Spring go Bad on a Rear Derailleur?
It sounds like your drive train was very heavily worn, and you need to consider replacing all the toothed components. Particularly the derailleur pulleys, as that is where you seem to have an immediate issue.

comment Does the term “domestique” have negative connotations?
Ummm... If you use expendable asset in a military sense, sure, that's negative. But using athletes in whatever way suits ensuring the overall victory for he team, doesn't quite meet that description. And, in the "cycling circles" I hang out with, "domestique" has no more negative connotation than does, say,"team player".

comment Does the term “domestique” have negative connotations?
Re-read your answer. All of your explanations for what a domestique are are accurate, but I don't see any support for this being a negative term. I just see you saying that cyclists who are domestiques, are working their way up in the industry while gaining experience. Why is that negative?

comment Cause of spalled cones?
I can't explain the physics of it, but when pitting is slight, it usually seems to start first on one side, and stay worse on that side, even when the other side starts to show it. At least in my experience.
