What brand - Wheels/tires? Fulcrum Zeros?

Add weight, that will give you more momentum downwhill, while the lighter wheels will help you uphill, you may come out ahead

Can't remember what sort of tubeless tires I have on them. They were designed to be lightweight and fast rolling, but not as light and fragile as a racing tire.

Excellent suggestion.

Repeated tests proved that the first result wasn't a fluke: try as I did, I couldn't get the bike to within 50 feet of where it usually came to a stop. It lurches forward from a dead spot with noticeably less effort, but it also seems to want to stop rolling the moment you stop pedaling. I'm very eager to see what all this will add up to when I take it out on it's first long ride this weekend.
Congrats on the new wheels. Sounds like the bearings don't spin as freely as they should or maybe it's your tires. The thing I noticed after purchasing my (new to me) used HED wheels was they seemed to spin forever. Try playing with tire pressures first.

The lower inertia of lighter wheels means that they will spool up more quickly and/or with less effort than heavier wheels, but it also means that they will stop spinning sooner when you stop pedaling; that's just basic physics. I was told to expect this by someone who swapped out his stock wheels for a set of Zipp 202's, but I didn't expect the effect to be quite as dramatic as it was.

When I have the opportunity to take the bike out for a real ride with my power meter on, I'll be paying close attention to the wattage I'm putting out to climb the same hills. It certainly felt as if the lighter wheels required less efforts on the climbs, but I have no hard numbers at present to confirm it.

Reading this thread made me want to ride again, holly crap 1 year of not riding destroys your shape. I used to do 30-40 miles a day and I did 13 yesterday and thought I was going to have a heart attack

no doubt savetheclutch. I couched it for 6 months and became a sloppy mess. Thankfully the last two weeks I have ridden at least every other day. Always surprises me how good pedaling does the mind and body.

I started riding again in 2011. Prior to that, I hadn't ridden a bicycle since 1977. Fortunately, sitting in front of a computer all day for decades kept me in excellent physical shape.

15 miles a day might be tough, especially if you live in hilly terrain. When I began riding again, 13 miles on a local trail seemed like a long, long ride. I remember being so exhausted at the end of a 20 mile ride that I barely had the strength left to swing my leg over the seat. Hard to believe, now that I'm doing hundred mile rides.

The same thing happened to me. Stopped riding the bicycle and went from low 170's to an all time high of 207lbs. When I started biking again a few weeks ago I thought I was going to die.

I feel a thousand times better, getting the exercise in. Pushing the limits is quickly changing my physique.

With a baby due in a month and a half I don't know how long I can keep up the cycling.

Has anyone used an internal geared hub yet?

I really like the idea of jettisoning a derailleur. The newest Shimano has 14 speeds but it could be heavy compared to the equipment it replaces.

For JRA and commuting they can be nice since they have very low maintenance requirements. Shifting at a stop is another advantage in most internal hubs. They are definitely heavy and don't really offer the fine-tuning you can get from a cluster and rings. I'm also unsure that you can get brifters that work with internal hubs, but that may have changed. That would eliminate modern drop bars unless you want to kludge with an extra shifter to mount.

What specifically bothers you about the rear der?

I re-started wanting to try for an hour.
That would get me to the bridge past the park on the bike path and back. It was hard the first few times.
Now, it isn't so much unless the wind is against me.
Oh, and that made for about 12 miles or so for me. There is this big hill at the end I have to deal with.
I was at 40 pounds up over my race-weight.
And it was fifteen years of desk duty and physical neglect.

The past week has been a re-visit of the flu season. Not horrible but a slight sore throat poked me away from riding Sunday worse Monday got me to skip riding and into bed early. The upset tummy, slight fever and the increasing sore throat nailed me Tuesday so that by Wednesday i was sleeping nearly the entire day shivering or sweating.
The fever broke sometime in the afternoon and the cats woke me about 3:30.
They promptly went back to napping.

I'll stay off the bike until Saturday just to make sure. Then see how things go for the weekend. I have some maintenance to attend to on the 990. Oil change and fuel filters. Re-set the idle and sync and such. I should get most of that accomplished Friday evening.
I'll never see 140 again or 1,500 miles per month or 23 mph averages with hills and climbing mountains, but I figure I can drop back to the high to mid- 150's and get to 150 miles a week sometimes more or less. And re-discover my old eating habits, but at a smaller portion size.

Oh, and I noticed the newest of my old bibs has threads worn off, so now I'm going shopping to replace two pairs instead of one.
They are only 4 years old!

I prefer a clean and maintenance free setup. The derailleurs need constant tinkering(mine do) to stay quiet.
