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.

@Ehryk, tinkering is fine.

@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.

done (bicycles.stackexchange.com/questions/9938); thanks for suggesting it!

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?

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.)

It's asphalt, and I'm on a touring frame (i.e., more or less a road bike).

I'd wager that any gear reasonable for ascent would be crazy on the descent. I'm happy to go 30 MPH; I just don't want to do 50.

@Unsliced, I have a Take-A-Look mirror and it gives superb visibility to the rear. I don't go anywhere without it.

add name of the angle, for clarity

the question is really about why the rims squeak -- clarify title

Wouldn't misadjusted centering of the brakes be a more likely cause for one to rub than dish error? I'd think the latter would be fairly unusual...
