I saw an article on it this morning, but I couldn't find any good photos or detailed information. All I know is that it's some sort of internal, or at least derailleur-less, drivetrain. The article made it sound as if it should be available in the near future.

Hi, I've heard of the Petespeed but I guess by now you will know a little bit more about it too as it's been introduced at Eurobike in Friedrichshafen. My uncle is the inventor of the thing so that's how I know about it. Anyway if you want to see it just check out: http://www.beone-bikes.com or http://news.southerndownhill.com/html/2004_BeOne_Drive_Train.html
There are some pictures there and a little bit of information about the Petespeed.

I imagine it works like the Honda gearbox, rocker arms and all.

I can't wait till this comes out on the market to buy on different types of bikes. Is the b1 with the new gear box going to be available soon?

Question.....The article on that southern downhill page said there was less power loss due to the chain always staying in a straight line. Looking at that gearbox makes me think that it twists more.

wow, really simple when you think about it.

It doesn't twist at all because the bottom cog is mounted on a splined shaft so it can slide over as it shifts. You can shift while coasting too!
According to Interbike, Hayes has liscensed the right to manufacture it in high quantity.

and as a nice side benefit, you can fit some decent sized BB bearings in there with the ISIS spline, most likely one better than the outboard ISIS stuff comming out.

Saw it this morning, coolest thing I've seen in a while. There is an mp3 of an interview with the inventor. When you think about it the idea is very simple, but man, he's one creative mofo to put it together. Looks really clean and simple. None of this complicated g-box stuff, just the same old goods we are used to in a simple package that hides it all away. Super cool.
