comment Mystery grease source - Alfine 11, Gates Belt drive, Shimano bottom bracket
It's hard to be certain from the photo, but it does look like the belt itself is deteriorating. This may be a longshot, but do you park your bike near a big copier or laser printer? Some of these devices are known to give off ozone gas, which can degrade rubber.

comment How do you install a bicycle pedal without a wrench?
Making a makeshift toe clip sounds like a disaster waiting to happen for a rider that doesn't normally use them -- something I might do if I was stranded and had no other choice, but I certainly wouldn't want to try to learn how to use home made toe clips on my ride home and risk snagging my shoe and not being able to get my foot out if I need to.

comment My lock was rusty and key snapped while trying to unlock bike so now its permanently locked
If you don't have tools to take the lock off yourself (though it's surprisingly easy for most locks if you don't mind spending a little time), just call a locksmith -- he'll use bolt cutters or an angle grinder and have it off in a few seconds.

comment Solar charger for iPhone whilst on a bike tour - is it worth it?
@AndrewWelch: The TSA uses grams of "lithium equivalent" to determine what's safe to bring on board. The upper limit of 25g for carryon equates to around 300 watt-hours of battery capacity. For a 5V USB battery pack, that's around 60,000mAh.

comment Solar charger for iPhone whilst on a bike tour - is it worth it?
TSA actually recommends that you pack lithium containing batteries in your carry on bag to better monitor them since Lithium batteries have been known to catch fire so they'd rather have them where you and flight crews can keep an eye on them. Though they don't prohibit them in carry-on bags.

comment Solar charger for iPhone whilst on a bike tour - is it worth it?
Does that stove really work well as a charger? It's rated for 2W continuous power output (4W peak), which is less than a computer USB port, so it must take well over an hour to fully charge an iPhone. That's a long time to keep the stove burning, plus the stove weighs over 2 lbs. If you have some way to expose it to the sun (on top of panniers?) seems like a small 5W - 10W solar panel would be lighter and less effort so you don't have to keep the stove burning for hours every night. The 7W GoalZero panel mentioned in another answer is $79, vs $129 for the Biolite stove.

comment Camera alternatives for commuting (2014 version)
One more for the list, the Monoprice Action Cam I've been using it for about a year and have been pretty happy with it. It's rated for 3 hours of battery life. It's not great in low light, but image quality is pretty good in the daytime. It's no GoPro, but for around $80, it's a pretty good camera.

comment What are optimal fabrics for cycling clothing?
I wear cotton on my commute to work in weather ranging from 40 degrees F to 85 degrees F. The cotton does get damp when I sweat (as do synthetic fabrics) so I just hang it on a hanger under my desk and it dries during the work day. While synthetics might be better at wicking sweat from the skin and are faster drying, I've found that I can use the same cotton shirt all week, while I have to wash synthetics every day or two to keep it fresh.

comment Techniques for safely leaving a bike for 1-2 minutes in a safe-ish place
I've heard a suggestion that you can turn the adjuster screw on your brake(s) to seat the pads against the rim, preventing the wheels from turning. Requires the pads to be close enough to adjust them to grab the rim, but it would slow the thief down (but maybe not for long). Similarly, you can use the velcro strap from your gloves to squeeze the brake lever, but this seems like it would be too easily defeated since it's so easily seen. But since bikes are easily carried away, the best thing to do is to lock the bike properly.

comment Anti-puncture options
I don't think that recommending brushing the tire while moving is a good idea in general. Not everyone has the same biking skills and it would only take a moment of inattention or an unexpected bump in the road to get a finger caught in the spokes, or glove caught between the brake and rim.

comment How to nail clipping into race pedals without looking?
When I need to clip without looking to see if my Look pedal is rotated up or not, I point my toes to the ground and push the top of my foot against the pedal -- then I can feel the difference between the top and bottom of the pedal. If it's oriented correctly, then I can pull up foot upwards, then slide my toe into the cleat, otherwise, I flip it and try again. Sounds complicated but (usually) works well with practice. Though I'm thinking of switching back to doublesided mountain SPD's on the road bike. With those, I just blindly mash my feet on the pedals and I clip in almost everytime.

comment Clipless shoes & pedals and long distance
In addition to SPD pedals with a platform on one side and SPD clips on the other (which seem to never be "right-side-up" for whichever purpose I want them for), there are also SPD pedals with the platform and clips on both sides, with the clip sticking out enough to clip in, but if you use a non-clipless shoe, it pushes down into the platform. These work well, but may have trouble with shoes that have deeply recessed cleats.

comment Where can I get some rags?
Ask your charity shop for discarded clothing/bedding that's not fit for resale -- they often get donations that are not suitable to pass on to anyone and have to pay to have it hauled away -- I'm sure they'd be happy to have you take some.

comment Weight of wheels vs. weight of tyres
I would say that lighter wheels will have less of an affect as lighter tires. When you put on lighter tires, the weight reduction is all at the circumference of the tire so has the largest effect on acceleration, but since some of the wheel's weight reduction comes from a lighter hub and lighter spokes, it will have a smaller effect. Though I doubt that the 400g reduction has much of a real-world effect at all.

comment Discouraging motorists from stopping at an intersection when they have the right-of-way
The other problem with drivers that yield right of way when they shouldn't is when the impatient driver behind the stopped driver doesn't always know why they are stopped or thinks they are stopped to discharge a passenger, so he speeds around them -- worse case, he speeds around the stopped car at the same time the cyclist enters the intersection. I've seen this happen and result in an accident (the car managed to stop and the rider was ok, just got knocked off his bike)

comment What are the effects of completely filling tires with water instead of air?
@CarsonReinke - Oh, I didn't know that option gave any indication that it was used, I thought it just gave you an answer box on the same page that you type your question in so you can write both question and answer on the same page. Is there some other indicator that shows when someone used that option?

@CarsonReinke - It's OK to answer your own question: Stack Exchange has always explicitly encouraged users to answer their own questions. If you have a question that you already know the answer to, and you would like to document that knowledge in public so that others (including yourself) can find it later, it's perfectly okay to ask and answer your own question on a Stack Exchange site.

comment What are the effects of completely filling tires with water instead of air?
I wonder how long the water keeps spinning around the inside of the tire when you come to a sudden stop, and if the resulting gyroscopic forces make it easier to balance at a stop. I think the water would only have a moderate effect on pedaling momentum since it's so loosely connected with the tire - it doesn't really "push" the tire around in a circular motion since the water is free to flow in a circle independent of the tire.

comment What are the effects of completely filling tires with water instead of air?
If my calculations are right, the water would weigh around 10 pounds. With a rim of radius R and a tire of radius r, the volume of the tire should be: (2 * pi * R) * (pi * r^2). For a 26" rim and 2" tire, R = 33cm and r = 2.54cm, so that's about 4200 cm^3 or 4200 ml, water weighs about 1 g/ml, so that's 4200g, or 9.25 lbs
