comment Why recover with carbohydrates, instead of with protein?
The longer you can put off hitting the wall, the better. Training at or near your anaerobic threshold already causes your body to increase its glycogen stores. Intentionally going over may have marginal benefit, but I would wager it's significantly less than the benefit of being on the bike for significantly longer.

comment How hard is it to disassemble and reassemble a bottom bracket?
Having replaced my BB before, I can tell you that like most bike maintenance, it's pretty straightforward and easy once you see how it's done. If you're lucky enough to have a set of self-extracting cranks (you probably don't), you won't even need a crank puller.

comment Aero Wheels, Velocity Wheels. Does it really matter?
Aerodynamics are huge at anything beyond casual speed, being the source of 80%+ of your energy losses on a bike. Presumably, if he's asking about aerodynamics and expensive wheels, it's probably a safe bet he's not looking just to improve his commute time.

FWIW, I am not a sports nutritionist. That said, my understanding is that long-duration training without carbohydrate intake will simply limit your available energy which will in turn limit the intensity (and therefore potential benefits) of your training. You may receive some benefit in training the muscles to retain more glycogen, but I suspect any difference will be lost due to a decrease in training effectiveness.

Not consuming sugar on any kind of long-distance ride will quickly lead to you bonking. Carbohydrates are an absolute must during a ride of any substantial length.

comment What do you wish someone had told you before your first commute?
+1 for taking the lane. Riding as far to the side as possible only encourages cars to buzz you.

comment Looking for Techniques for Riding Uphill on a Single Speed
There's nothing wrong with him using a single-speed bike. He had problems climbing hills, the obvious answer (to me, at least) is to drop a few gear-inches and make them easier. He'll have to spin faster on the flats, but that's much better on his knees and for building endurance than mashing on the pedals is.

No problem. Keep in mind that every tooth added to your cog is about the equivalent of removing four teeth from your chainring, so chainrings let you make finer adjustments to your gearing. However, they also tend to be way more expensive. I'd try a cog that's one tooth larger, and if you're spinning way too fast, get a chainring that's two teeth smaller and put the original cog back on.

You don't need to drop your gearing by much — just go a tooth or two smaller on your chainring. Or if you don't have a smaller chainring, go with one tooth more on your rear cog. You'll notice the difference climbing hills, and you'll learn to spin faster to compensate on the flats. Don't downvote me until you've given it a chance; higher cadences are a good thing, and shouldn't be feared.

Voted up for being more comprehensive than my single-minded answer. :)

comment Do Mandatory Bike Lights at Point of Sale Save Lives?
Furthermore, it's obvious from the content of your question that your mind was already made up on the issue (a rep bounty for a draft UK law?), and what you were really hoping for on this question was validation and support for your beliefs rather than counterarguments. I suspect that's why your question has been rated so negatively.

comment Do Mandatory Bike Lights at Point of Sale Save Lives?
I gave you the facts. Cycling at all is more beneficial than not, regardless of the use of helmets or lights. Just over 40% of cycling fatalities occur at night, and I've seen estimates that peg perhaps 50% of those on inadequate lighting. Combined with the 9-times-safer figure, you would have to save forty-five lives for every person you discourage from using a bike. Not worth it.

comment Do Mandatory Bike Lights at Point of Sale Save Lives?
Read my argument again, this time more carefully. The risks of cycling are outweighed seven to nine times by the benefits. Increasing the cost of bicycles by requiring an optional component will reduce the number of bicycles purchased and therefore the number of cyclists. Anything that reduces the number of people cycling will have an overall detrimental effect. Also, if the tariff could be reduced, then it could be reduced without adding back in the cost of bicycle lights, which would have an overall greater effect on public health.
