comment How many miles of riding require the same effort as one mile of running?
This is a great answer. I do have one issue with comparing running to cycling times in an Ironman: fatigue! Running comes after cycling, so it is natural to assume that the contestant will be running at a slower pace relative to cycling than they would were the two events reversed. That said, this is probably mitigated somewhat by the significant endurance requirement (it's probably better strategy to maintain as equal effort as possible across both events). It would also be interesting to consider the ratio for both sprinting and endurance distances.

comment From Delft to Rotterdam - Hard?
That's precisely why I said it will be easy for a 15km ride. I don't know your physical condition, so I can't say whether or not you, specifically will find it easy. But I can say that if you're going to go on a 15km ride, this will be one of the easiest. Even for a beginner, 15km is really not that far — it will probably take you on the order of an hour or so. But it depends on how hard you push yourself. It could range from anywhere between a lazy 2 hour jaunt where you barely feel exerted, to a 20-minute balls-to-the-wall hammerfest.

comment Is it possible to shorten a chain?
Not if you plan to use your front derailleur.

comment What does chain worn indicators 75% mean?
To clarify a bit, replacing your chain before it is completely worn is what will prevent your more expensive components like front chainrings and your cassette from needing to be replaced.

comment What are the practical limitations of a road bike compared to a mountain bike?
It's also probably a function of the amount of money invested in that bike. I wouldn't give a shit hopping curbs on a $70 MTB; worst case scenario, I need to buy another $70 MTB. On a $1,000 road bike, if I taco my wheel I might be out $200 just for that one component. People tend to take better care of their nicer possessions.

comment cars and scooters in a road bike race
Motorcycles aren't exactly mixed in with the cyclists; they don't ride in the peloton. They typically will ride off the front or back of the peloton (there's usually not room on the sides, as the peloton will widen to occupy the entire road). For breakaway groups, they have a bit more freedom to ride parallel to the paceline. You answer seemed easy to misconstrue as motorcyclists being allowed to actually ride in the peloton or in pacelines.

comment Is it realistic to fuel a long ride with NO sugar?
There's not a direct conversion between calories to watts. 800kcal/hr is way beyond plausible — typical rates, even for a hard ride, is somewhere around 300kcal/hr.

FWIW, whole grains basically are sugars. Do you mean no added sugars, or no carbohydrates whatsoever?

Practice a bunch?

comment Why does reducing bike weight have such an impact on speeds?
Stiffness also factors in. The stiffer the BB area, the less power lost to frame flex. How much, I couldn't say. But the reduction of mass for climbing, increased stiffness and reduced friction for increased power to the wheels combined probably add up to something noticeable.

comment Must a Bicyclist Riding on a Sidewalk Stop at a Stop Sign?
More importantly, you shouldn't be riding on the sidewalks anyway. Established consensus is that it's significantly more dangerous than riding on the road.

comment Why use multiple materials on chainrings?
Excellent answer. I would have intuitively considered the force aspect, but having more teeth engaged in the big vs. small ring is also an important distinction!

comment What kinds of kickstands are good for touring?
+1 for click-stand. Touring right now with one for the second time, and it's one of the most useful things I have for my bike.

comment How to center a quick release rear wheel regularly
Because this locking approach allows you to use the smallest possible lock. Smaller locks weigh less, and more importantly, mean less room to insert a bottle jack, and less leverage from a crowbar.

comment How to center a quick release rear wheel regularly
If they can cut through your rim, they can save themselves the trouble and simply cut through your U-lock anyway. A rim is a pain in the ass to cut through — it would be continually pinching the cutting device, given the strong inward pull of the spokes.

comment What are the benefits of nickel-plated chains?
If your chain is rusting before a chain-checker gauge says it's worn out, you're not lubing your chain enough, or you're not riding your bike enough that a high-end chain will make a difference.

comment Why are some bikes sold without pedals?
It's not just a matter of the tire choice being personal. It's that the customer probably doesn't already have a spare set of tires (and usually the shop will swap them out if the customer requests it). But they very frequently do already have a set of shoes that might be incompatible with whatever pedals the shop were to put on the bike.

comment How to train for a long tour?
I agree with @DanielRHicks. The Tour Divide is not something you want to start on this sort of path with. You'll definitely want to get some centuries and a double century or three under your belt first, then use some vacation days to do a 50mi/day week-long tour. Don't underestimate how difficult this ride is.

comment Why do some road bikes cost more than motorbikes? Are they grossly overpriced?
@DanielRHicks I'm not so sure about your comment about Shimano. That may have been the case a few years ago, but SRAM is really starting to eat into their market share. Shimano is not nearly as dominant as they used to be.

comment Do the benefits from Cycling outweigh the harm of pollution
I don't have access to sources right now, but generally speaking the net effect of cycling is about 13 minutes of lifespan gained per mile ridden (or roughly 2.5 hours of lifespan gained per hour of cycling, compared to a sedentary lifestyle). The health benefits of cycling without question greatly outweigh the net of all additional risks combined. This is, of course, on average, so specific cases may vary; I make no claims as to the safety of cycling the wrong way down streets on a smoggy day in Beijing while drunk.
