comment Should I listen to music when I bike?
A different framing of the previous comment: The behavior of others affects my own safety. It's difficult to find a situation where one really can "decide for yourself" and one's choices don't affect others. Therefore, it's reasonable to ask others to behave more safely; i.e., yes, it really is OK for me to have an opinion about your behavior while on the bike.

comment How can I tell the difference between a J.I.S. and ISO square taper bottom bracket?
@Kibbee, yeah, I saw that Ritchey was in the JIS list. I'd love some way to verify that independently. Regarding the interchangeability, it sounds like the length spec gets confusing, so I'd like to avoid that.

comment What is the hand gesture for “I'm sorry”?
Don't yell. It's unlikely you'll be understood, and you risk just seeming angry.

comment How do I test ride a bike that I'm looking at buying?
+1 for longer ride. Good bike shops will let you take a bike you're serious out for quite a while. I believe I rode mine for 20 miles before buying it.

comment How to buy machine-built wheels for a touring bike?
FWIW, I ended up with machine-built wheels from Harris Cyclery, and I paid the extra $20 or $40 to have them hand-adjusted before shipping. Under $300 total for a wheelset.

Believe me, dropping several pounds of fat is on the agenda too! And I'll see about becoming 25 again. :)

comment Are there devices to moderate speed on mountain descents without braking?
I believe base metabolism is more like 100 watts, but I haven't looked it up.

@Jack, brakes aren’t “just fine”. It’s tedious to keep braking on a 1-2,000 foot descent. They do work, but it would be a much more pleasant ride if my terminal velocity were more reasonable. I’m not in it for the adrenaline; others may be.

comment Are there devices to moderate speed on mountain descents without braking?
Thanks! Do you know of any online resources that could help me estimate drag in watts based on surface area? I found some resources (e.g., my.execpc.com/~culp/rockets/descent.html) that offer calculations giving a drag force, but I don't know how to convert that to watts. Or am I framing the problem incorrectly?

comment Are there devices to moderate speed on mountain descents without braking?
Regarding “learning to descend at speed”, the natural equilibrium on these descents is 40-50 MPH. The posted speed limit is 25 MPH, which is quite reasonable given the tight curves. I don't have any desire to blast through such curves, which are atop cliffs and are often the steepest parts of the ride. Thus, the basic point is that I'd rather descend more slowly overall, rather then accelerating to 50MPH on the straights and having to brake sharply before entering curves. (Similarly, the routes are so steep that a “slower” bike would have little practical effect.)
