comment Which brake is most expendable?
Giving a percentage for stopping power in this way is misleading. In practice, the brakes provide stopping power in proportion to how hard you pull each the lever, with the rear brake tailing off to zero stopping power as the front brake is pulled harder. The rear brake may be capable of providing 60% of the stopping power (I'm not sure about the number) of the front, but due to weight transfer, the stopping power isn't simply additive.

Also, in addition to simple brake failure, having only a front brake is particularly dangerous if you're ever in a scenario when you might lock up the front wheel. Ice, wet roads, loose gravel... a rear brake is a cheap insurance policy.

Beat me to it by a few seconds. The front brake is crucial, but removing any brake for weight reasons is generally a horrible idea. Fixie riders can get away with a single brake because they can use the drivetrain to skid the rear wheel, but road bikes don't have that luxury.

Rolling up your pant leg also allows you to arrive at work with clean clothes. :)

comment I want an cool urban/track bike with 3speeds. Could you recommend me one?
Given that the defining characteristic of a track bike is its fixed-gear nature, exactly what traits are you looking for?

comment Should I fight a ticket I got for riding my bicycle in a crosswalk?
Her story was ambiguous, but this may have been a scenario where crosswalks were present without pedestrian signals, which gives the right-of-way to pedestrians in most jurisdictions. Of course, bicycles are not pedestrians, so...

comment How fast does new technology “trickle down” to lower models?
High-end models often can have less durability than lower-end, too, simply because durability is sacrificed in order to shave off quarters of a gram here and there.

comment How do you shift your weight when leaning on a turn?
That said, Cancellara never leans farther into a turn than his bike. He often leans his bike further (0:54) than (1:31) he leans (4:06) his body (4:22). Draw a line between his head and his hips and it's plain as day — his legs might be big, but they're not that big.

comment How do you shift your weight when leaning on a turn?
The slipperiness of the course doesn't matter at all. The technique to maximize your traction is independent of that factor, and the highest speed at which you can safely turn is entirely determined by your traction. So, a skilled descender is always going to be using proper technique on any turn sharp enough where grip is a limiting factor for speed.

@DanielRHicks I think the popular video of Cancellara's descent in the Tour de France counters your point of view here. If you watch closely, Cancellara leans his bike into sharper turns considerably more than he leans his body. You want as much downward force over the wheels as possible, and by leaning your body farther into the turn than your bike, you produce greater lateral force and reduce the downward force, increasing the chance of a slip.

You might also want to mention putting as much weight as possible on your outside foot.

comment Chain slipping off a non geared bike
If you replace the chain after two years, you may have to replace the rear cog as well. As the chain starts to stretch, it doesn't sit perfectly between the teeth, and will reshape them over time. This may be less of an issue with single speed bikes, since they can thicker cogs than geared bikes. But it's worth checking to see if your cog is worn as well, particularly after such a long period between changes.
