    It was on a Metafilter thread. There's some interesting comments, but the end of the thread got sidetracked into a counter steering discussion.

    From the thread:

    The Chicago bike share system is huge. Check out the map here. Each flag shows how "full" the station rack is.

    A 3.7 mile version on Strava.

    The Tour de Bloom pdf has this profile. But it looks like 4.0 miles on the chart. Maybe the time trial starts a little farther downhill...

    The climb is exactly an 8% average grade. For me, it is my 34-28 all the way, at an average speed somewhere between 4.5 and 4.75 mph, 50 to 55 rpm, VAM 550 to 600. Almost an hour long climb, around...

    Campagnolo had different cog orientations for the same tooth cog on different cassette sizes. For instance, the 19 cog might be a "19A" on a 12-25 10-speed cassette, or a "19B" on a 13-29. The...

    And you won't hear it, it will be way quieter than my cordless drill, even though it uses the same type of gear reduction. Uh huh.

    And this from Abbey Bike Tools. Reviewed. But it's $50 instead of $7. A cool tool, though.

    Yes. It worked perfectly the first time I ever had used CO2. It's easy to control the gas flow. The 20 gram cartridge is for MTB tires.

    There are many styles of brake levers for aero bars. See this image search. They might be too far of a reach for a thumb. I assume the aero bars are...

    That looked very odd. So I googled "scott foil steerer plug" and found this photo, and this old thread that explains it.

    Well, strava seems to be in the ballpark.
    The last Garmin GPS recorded ride I uploaded to strava:

    Avg speed 15.7mi/h max 38.9mi/h

    That's not exactly the formula (multiply by .22). But see an even easier formula at the Powertap site:

    calories = average watts x hours x 3.6

    So 100 watts for an hour is 360 calories.

    It's better to buy tools as you need them. That set has a freewheel remover, a headset lockring tool, cone wrenches, and a crank extractor. But those are more for specific older bikes. And it's...

    A no-drop group ride that's too big to count will use a sweeper rider. That rider stays with the slowest rider in the group. Then the group leader waits at turns until the sweeper arrives.

    It's not tricky to true a G3 wheel. The only unusual thing is that the pair of spokes should both have equal tension. It's possible to have the wheel quite true, but with unequal tension in the...

    With the same riding position, it takes 50% more power to go from 14 mph to 16.5 mph.

    Wow, a 1920 era bike. With 1x3 gearing, and shifting by loosening the axle wingnut and moving the chain by hand. It has wood rims, I think. Sketchy sidepull brakes. Two spare tires. New spokes?...

    Is this a 300 to 400 mile one-way ride? I would consider something like Roanoke VA to Emerald Isle, about 300 miles. You could add some miles on the Blue Ridge Parkway that passes near Roanoke.
