They are great if you like to work harder to get where you are going for no apparent reason.

Drive shaft bikes are much less efficient than a chain driven bike. That is why bikes have chains! There were shaft driven bikes in the 1800's and there is a reason the technology is not more prevalent.

When something goes wrong with it you have a much heftier repair bill to boot.

You are also stick with a single speed or internally hubbed drivetrain which is a big limiter.

The commuter link you give is filled with half truths and misinformation. Especially regarding road vs. mountain position. Both bikes should be equally comfortable when fit properly.

Most "new" bike technology was tried out decades before. With the exception of mountain bike technology which is mostly stolen from motorcycles, little new has been develpoed for bikes in a very long time(I know a few things are new!). Whenever a new fad pops up, there is usually a reason why it is not already mainstream.

In my opinion shaft driven bikes are just as ridiculous as the "new" coasting group. Just regurgitating already failed technology in the name of having something "new" to market.

Just install a chain guard if you're so concerned. On my fixie I've never had an issue with getting my pants caught in the chain, or having the chain get grease on my pants.

I only got as far as the first paragraph on your link, which talk about road vs. mountain. The person who wrote that article has obviously never really ridden a bicycle for anything more than a little joy ride down the street. Which is cool, but i wouldn't put to much stock into what it's saying.

the link is a joke, as is the person who wrote it. take it from the people who ride for work, for fun, for transport, a driveshaft on a bike is ridiculous. if its so wonderful, why do motocycles still use chain drives?

There is a new bike shop in North or Northeast that has some of the chainless bikes...try one for yourself, sorry I can't remember the exact location or name.

Here's (http://www.bikeforums.net/showthread.php?t=191150) a good long-term review of riding a chainless bike on another forum.

It's a beautiful bike. Shaft drive is really smooth. Bike looks really cool (in my honest opinion). It was a present from my wife, so it has a special place in my heart. Might make me biased. I've had it for 3 years and so far haven't had a problem with it.

There are several motorcycles that use shaft drives out there. BMW is probably the most prominent. I think that all of their bikes have them.
For motorcycling, they are very efficient and useful - especially for touring. They have much lower maintenance requirements and last a really long time. Riding a motorcycle with a shaft drive is a little different than a chain drive and it takes a bit of getting used to.
As for a bicycle, I am not sure what the big advantage would be.

Sure feels to me like more than an extra 2% effort that's needed on a shaft-drive.

That Cycling Center sure did suck when I visited it (http://www.bikeportland.org/forum/showthread.php?t=430&highlight=shaft). I wonder if they've improved since then.

Edit: They changed their name to Cascade Cycling, which is a good step.
