comment Why exactly did Boardman manage a further distance than Wiggins?
It's extremely uncomfortable, and it's also quite difficult to control the bike in this position. It's best used when you're the only one on a velodrome track. There's a reason stuff like this isn't allowed in competitions.

comment Are Hövding helmets safer than regular helmets?
Good to hear comments from an actual user. My biggest problem that I can see is that it isn't actually reusable. Neither are regular bike helmets, but I've have fallen 4 or 5 times in my time cycling, and only once have the actual helmet come in contact with the ground. And even that time it was an ever-so-slight contact that I didn't feel the need to replace the helmet. Replacing a $300+ helmet every time I had a fall could get kind of expensive, even if it was less than once a year. Also, it looks like it could be easily push around the back of the head if you hit it from the front.

comment back tire keeps going down
When putting it in water, make sure you pump it up big, like at least 1.5 times as big as it would be in the tire. Also, try squeezing the tube as you place it under the water. If you still can't find the hole, maybe just get a new tube. They aren't very expensive. Just be sure to check the tire for debris that caused the existing puncture and remove it.

comment Do certain makes/models/types of bikes get stolen more than others?
Yeah, the professional bike thieves can get pretty nasty. Even the best locks can't stop them. I know a guy who has his stem removed and his forks stolen from a nice mountain bike. I guess there's security nuts you can get to make it harder to disassemble the stem. However, when somebody is willing to go through the trouble of disassembling the bike to steal individual parts, If you aren't careful about it, you could probably take most of the important components off a frame in under 20 minutes.

comment Why aren't hub/drum/roller brakes suitable for touring?
I'm not familiar with them, but I think there's a certain complexity to them that isn't welcome when touring. If something goes wrong and you're 100 miles from nowhere, it's going to be difficult to fix. With rim brakes there's very little that could go wrong, and you could always bring spare parts with you in the event that something does break. Also, I've heard of people being weary of disc brakes for the same heat and heavy loads concerns that you have with hub brakes. Most "real touring" bikes will come with cantilever or v-brakes.

comment Fundamental principles of tire friction for off-road biking
Speaking of downward forces, cars have the ability to generate their own downforce using wings. This means they can generate more force on the ground than can be done just with gravity. F1 cars can generate as much as 5 G's of downforce. Something like this simply isn't possible with a bicycle.

comment Fundamental principles of tire friction for off-road biking
One major difference between mountain bikes and car racing (assuming asphalt) is the surface that the tire has to adhere to. It doesn't matter how sticky the tire is when there is loose gravel on top of hard pack dirt or wet leaves on smooth rocks. When the trail doesn't adhere to itself you're going to get very bad traction.

comment How is Sir Bradley Wiggins 3D printing his titanium handlebars?
The real question has to ask is "Why?" What advantages does a titanium handlebar offer? According to the article, the bars are custom fit to his arms, but I think that could have been achieved with more traditional methods. I think the 3D printing is more to draw attention to his effort than to actually provide any real advantage. Interesting that it looks like they've relaxed the rules a bit on what types of bikes are allowed for the hour record.

comment Adjustable stem issue
I had a similar stem and it was fine when I bought it. as soon as I tried to adjust it, it started to wobble, and I never did get it right. I rode it for a year like that. Eventually I ended up getting a solid stem because I felt it was unsafe with the wobble, even though I never really had an actual problem other than a slight wobble.

comment Frame manufacturer?
Without any identifying markings like a head tube badge it's very difficult to identify a frame as many are made overseas. Even bikes from different brands with use identical frames with a different paint job. It looks like a pretty basic hybrid frame. Is there any reason you want to identify it?

comment Pros and cons of single-sided forks (Cannondale Lefty)?
Your body, as well as the handlebars, cranks (counting pedals), and possibly rear triangle are still going to be wider than even a double sided fork. So I'm not sure what advantage is offered in "width" by not having one of the forks.

comment new chain skipping
You should be able to tell if your cassette is too worn from a visual inspection. If you teeth are pointy then they worn too much. Take a look at this image. The teeth on the cog below the chain are worn from excessive riding in one gear, while the rest of the cogs seem to be in pretty good condition. As @DanielRHicks mentioned, you can take it to a bike shop to measure if you aren't sure, but if it's at the point shown in the picture, it's definitely time for a new one.

comment Help for a 169 mile bike ride
I don't even know how going only 10 miles a day would work in reality. Where would you even sleep? You most likely want to be in a place with a hotel or designated camping area every night. Sure you could just duck into the bush and pitch a tent, but that seems like it might not be the best idea. You'd have to have a very good route planned, because depending on where you go, it could be 40 miles between places you could buy food. Packing 4 days worth of food and water (although purifier or chlorine tablets may be an option) would make for quite a bit of extra baggage.

comment Why are riders allowed to draft behind cars in Grand Tours?
Almost makes you wish there were no cars and riders were required to fix their own bike with equipment they carried with them.

comment Shimano 105 10 and 11 speed compatibility
Also, you'll probably be able to buy the entire group set for less than everything minus the cranks, so you might as well upgrade the entire thing at once. Especially when you consider that it will be much easier to sell your old groupset as a complete set.

comment Why should you not just buy the chain with more links?
I looked and guess you are right, they do exist. I can't think of why they would do this. You'd never be able to make it so that people wouldn't have to remove links. Even on bikes with the same size cogs and cassette, the difference in chain stay length would still mean you need to adjust the chain length.

More meant as a joke, buy you should probably donate them to your local bike co-op rather than start throwing them out when you get too many extras.

comment Why should you not just buy the chain with more links?
Eventually you could use all the left over pieces of chain and put together a whole new chain. At 8 extra links per chain, that would only take 14 new chains to create a whole chain from the left over links.

comment What is the hydraulic brakes expected life?
These are Acera level brakes, which is on the lower end. I really wish they'd try to keep things more simple (ie. cable actuated) on their lower end components. Way easier to repair at home, and a lot less that can go wrong.

comment What is the benefit of Shimano Click'R technology?
If you're interested, I would probably try to find a bike that stocked them and see if they have a way to let you try them out. From what I understand, they are easier to clip into and out of. Based on the link from @FocusedMuffin, about 60% easier to clip into and out of. It's already pretty easy to clip into and out of SPD to begin with. You'd probably be better off trying it for yourself then trying to gauge the feel of the pedal from what people wrote on the internet.
