And the probably paid someone a buttload of money to design that site.

This is one thing that really bugs me about SRAM (Avid, Truvativ, etc.). They have some really good stuff, but trying to get the most basic information requires a lot of waiting for software to load and run, and guessing where to locate the item you're interested in. Getting detailed technical information is pretty much impossible. If I'm doing it wrong, please enlighten me.

This device makes alot of sense.

I've heard of similar devices (possibly even made by the same company) made for racing unicyles.

There was a Japanese five speed crankset once; I've seen pictures of a Miyata-branded one on a Miyata bicycle. Someone posted it on the Folding Bike forum a year or two ago.

This may or may not be a useful item; depends on the gear range and the price, among other things all not mentioned on that totally lame web page.

Edit:
Sorry, got the details wrong. It was a Miyata 5-speed internally geared crank mounted on a Strida, which would make a totally cool commuter. Here's the thread.

I know people have paired a Schlumpf to a Rohloff for some insane gear range, but who really needs that? I wouldn't want the extra drivetrain resistance if I didn't have to have it.

Yeah but commuters probably want a wider gear range and don't need the ground clearance... so not really a commuter thing.
