doteasy is serving a 200k "exceeded" page to protect themselves from serving
about 50k of page?

Maybe it's marketing, but "Look! I'll randomly embarrass you in front of your
readers!" isn't much of a selling point.

Here is a "competitor" which I have found extremely useful when choosing
drivetrain parts: [http://www.gear-calculator.com](http://www.gear-
calculator.com)

These are really helpful if you have a bike you mostly like and want to
upgrade the gears, or if your current bike doesn't have the gears you need. It
has become especially important during the recent trends of moving from 3x
front gears to 2x to 1x.

Nice upgrade. I still use Sheldon's site occasionally. The web in 1998 was
still pretty great :)

I also look at his site. I discovered it maybe 3 months before he passed away,
it still makes me sad.

Would someone explain to me why this information is useful? Maybe it is
because English is my second language, but I didn't understand the meaning of
the displayed information. I cycle a lot and it looks interesting.

In my opinion, this visualization is not particularly compelling if you don't
already know what you're looking at, and I can relate to your sentiment of
confusion.

This is a tool for analyzing and comparing differences between drivetrain
setups. A bicycle drivetrain is typically composed of a single gear, or two or
three gearing choices "up front" (on or near the crankset) and either a
single-speed "rear", or anywhere from two to 30 (!) [1] selectable gears at
the rear hub.

The various "output" modes from this tool are all derived from the Gear Ratio,
usually simply the ratio of the number of teeth "up front" to the number of
teeth "in back" for any given selected gear.

By entering multiple drivetrain setups, you can quickly compare overall range
between different drivetrains. You can also see the "steps" between different
gears within a given drivetrain, which tells you how many pedal cadence
choices you'll get within a given comfort zone for the bike's intended riding
purposes.

[1] SRAM's DualDrive 3x10 internally-geared hub with a standard cassette and
derailleur.

I avoided mentioning it because I couldn't remember off the top of my head
when writing the above comment, but Pinion also makes a gearbox that sits next
to the crankset and offers up to 18 gearing choices!

As of 30 Dec 2015 @ 0822 hrs US CST, the link generates a Traffic Quota
Exceeded error. Heck, that's one of the reasons why I still occasionally
peddle to work.
