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 What is the carbon footprint of a new bike?
@kibbee: True in some countries. In the UAE, and a lot of Asian countries, not so much. Around 35% of the population in Dubai owns a motorized vehicle. The remaining are bound to public transport, and bicycle or foot traffic. Still worth considering, and perhaps it is the countries which are decentralized to the point of vehicle ownership being essentially mandatory where these questions will carry the most weight, so it might be moot.

Also, can you define or link definitions of the energy measurements you are using? You can get some referential data from the fact that a number is higher or lower, but there aren't good explanations of the measurement units, and frankly, although I assume higher is worse in this case, that could be the opposite in some systems.

comment What is the carbon footprint of a new bike?
FTR, I'm not attacking the answer, just seeking clarification. I would argue that the question is requesting a direct comparison of the complete manufacturing and use footprint of an automobile to that same footprint for a bicycle. It seems obvious based solely on material size and weight (for shipping) that the car will use more resources per manufactured unit, and in addition continues to increase that use through fuel and maintenance consumption throughout its useful life. Is there something counter intuitive here that I am missing?

Good research, but could use a bit more explanation of terms and organization. For instance how do you define toxic load? Is it alleviated by sound manufacturing processes, as required in US manufactories? Or does CF by the existence of the material itself automatically carry a high load, with no workaround possible (or currently available?) You would add the cardboard container and the plastics used to ship to the cost. Cardboard is recyclable and plastics used in our bike packing are minimal (180 grams) and reusable. Do these ameliorate any responsibility in your view?

comment What's causing soreness in front upper thigh?
If the saddle is tilted nose up, that is most likely the cause, yes. The measurement you took, as described is perfect. High point of the aft saddle to the high point of the nose of the saddle. Make it level, and give it a try again.

It was a joke. I mean, surely, a carbon frame has a major carbon price tag?

Is it carbon frame? That will add to it significantly?

comment How to measure calories burned?
Agreed that it a complex process, and that no system will be 100% accurate, even in a lab IMHO, but a power meter on the bike is a direct measurement of watts produced, and that give you a very consistent place to start the math that accounts for all of those differences in position better than any other consumer grade system. If you've seen the systems like the cyclefit trainer, or the spinscan trainer, you get a real feel for the way position affects power and consistency, along with caloric burn.

comment Mountain bike tires for rocky, steep, dirt trails?
And how does one attract the attention of the person from whom you wish an answer, if you can't discuss it where it occurs?

Except here is where the action took place, so here is where I questioned it. How about you answer it?

@ChrisW: WHy would you edit the title to radically change the meaning of the question? Neil didn't choose to do so, and the OP had the option to follow Neil's advice or not. Is it accepted practice for you to do that? For the record, it would irritate me greatly if it was my question. My first instinct was to simply change it back, but that would be as bad as you doing it to begin with.

comment Can I use an inner tube that's too narrow for the tyre?
That sucks. But most people really only have the weekend to do what's important. And shopping online for small parts in particular will eventually deprive you of the resource you need when you most need it.

Why the down vote, Neil? Did you disagree with Stephen? I thought you were supposed to explain that kind of thing?

comment Can I use an inner tube that's too narrow for the tyre?
Because those same forty guys are the ones who always want right now service on their bikes when they need something, and expect that I will drop everything to make their "emergency" go away, but won't buy a tube from my shop if they can get in 10 cents cheaper somewhere else?

comment Can I use an inner tube that's too narrow for the tyre?
Let's see. Because the shops and mechanics who make sure your bike continues to function when it gets outside your skill level to repair need to survive to be there when you need them. Because I can almost see an argument for purchasing luxury and specialty items online, whether I agree with it or not, but when you take the absolute basics away from your local economy, you undermine the very thing that makes our economy function? Because I know maybe one out of a hundred guys who are avid cyclists who doesn't hang out at the shop to BS and pick my brain, but 40 of the same guys buy online?
