comment Have replaced v-brakes and they still squeak. What to do?
Another thing to try is to wrap the brake arms with something like rubber (not plastic) electrical tape.

comment Have replaced v-brakes and they still squeak. What to do?
I suspect that a part of your problem is your constant sanding and cleaning. Have you tried simply leaving them alone and tolerating the squeal for awhile, to see if it gets better?

9 months of riding 8km/day is not nearly enough to wear out standard rims, unless one is doing some really gonzo riding. (Though with all the sanding he's done I suppose they could be getting a little worn.)

comment Whole Bicycle Rack Easily Removed! Is the provider liable?
Maybe the thief was the owner of the other bicycle, who had lost his key/combination. (Or, possibly, the thief locked both bikes to the rack so that he could come back later and steal them.)

comment The paint on my bicycle is damaged
A week is nowhere near long enough for many paints to fully harden.

comment The paint on my bicycle is damaged
Soft paint and a hard clamp. Paint often takes weeks to fully harden, and sometimes paint (or, more significantly, varnish) will not fully harden at all, because the humidity was too high when it was applied.

I don't normally like to contradict Sheldon, but I recall, maybe 15 years back, seeing a video where a "skilled" (stunt) cyclist intentionally locked the front wheel. He went head-over it the blink of an eye, and I seriously doubt that the rider was not "braced against the deceleration".

comment What makes one road tire have a less “bouncy” ride than another?
Well, at the same pressure the narrower 25 would be slightly softer. And presumably even the same width would be slightly softer in a non-puncture-resistant tire.

And if the thief had the time and tools to remove the rack, he could just as easily have had a Sawzall to cut through the rack.

I doubt that you can prove liability in court, though the store's insurance company might be willing to provide some sort of settlement. (One wonders what you were doing "for hours" at a supermarket. The store will argue that the rack was for customers.)

Just out of curiosity, what do you mean by "less bouncy"? Were you previously experiencing some "bob" when pedaling that is now less noticeable, eg, or is it simply that the new tire seems harder.

comment Why do we rarely see recumbents and almost never see velomobiles?
Wellllll, given how much regular cyclists look down their noses at 'bent riders, do they even have noses long enough to deal with "velomobile" riders??

comment Protocol for slipstreaming another cyclist?
Most analyses have shown that, in cycling, the "draftee" does not suffer measurable energy loss due to being drafted. There is a significant amount of added stress, however, due to needing to be concerned about the drafter, not making sudden changes in speed, etc.

comment How does a two wheel drive bike work?
Hmmm.... That's a chain drive with a bit of a Rube Goldberg gear mechanism at the top of the fork. Seems like it would apply significant unbalanced torque to the steering tube. And the long chains would be apt to collect trash when off-road.

comment Could I be pumping up my tyres the wrong way?
I'll add that the classic example of a pump with poor compression ratio is your inexpensive "compact" frame pump. Such pumps are rarely capable of achieving more than 50-75 PSI, even if you sit there and pump for 30 minutes.

comment Could I be pumping up my tyres the wrong way?
When you have the problem that the tire is hard to pump from the start then a bad valve, improperly connected chuck, or something similar is a likely cause. But if the pump simply gets harder and harder to use as pressure goes up, then it is, as you suggest, the pump geometry that's causing the difficulty.

But asking "what brand/model" is of little use unless the pump happens to be one of a small number of well-known brands/models where the design pressure can be identified.

comment Could I be pumping up my tyres the wrong way?
A pump's max pressure is limited by its compression ration. A "general purpose" handpump (designed for car tires and kids' bike tires) will generally only be good up to 80-100, whereas a pump designed for high-pressure tires will be good to 140 or above.
