comment My front wheel steers right. How do I solve it?
Holy hell. Ever since I've been riding a new (to me), bike, I've been unable to ride without holding the handlebars, despite it being trivial on my previous bike. I've never been able to figure it out until now. Turns out, it was the seat. Have an upvote, sir.

comment How to protect myself when falling off the bicycle
Even given the update, I believe that this advice is dangerous and misses the point. When you are involved in a crash, the number one priority is to protect your head. The number two priority is to protect your limbs. Period. Considering the physics of a fall assuming you are a spherical body is irrelevant to the forces experienced in an actual crash, and any reduction in force you experience from extending your deceleration is immaterial unless you are crashing into a solid obstacle like a wall. Your body does not experience significantly more trauma in a 30ft slide versus a 35ft slide.

comment How to protect myself when falling off the bicycle
Stated differently, the physics provided considers your body as a singular mass, and recommends an approach that may marginally decrease overall force experienced by your body while significantly increasing the risk substantially higher forces on localized parts of your body (e.g., limbs). Unless you are a perfectly spherical mass (hey, I'm not judging here), this advice gets the physics (mostly) right but completely ignores context.

comment How to protect myself when falling off the bicycle
I think the actual advice in this answer is dangerous. First, I remain unconvinced that anything you can do during a wreck will significantly increase or decrease d. But worse, what actually causes serious (non-head) injury in a bike wreck is usually having limbs broken while tumbling. Extending your arms and legs is an extremely bad idea, and will more likely than not contribute to broken limbs.

Great idea. I've added one.

comment What would cause variable air resistance on a day with no wind?
It's a nitpick on your comment, but it's closer to 7.5% power difference at constant speed, 7% speed difference at constant power. Also don't forget to accept, if you think this is the best answer. :)

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.
