Looks like a solution in search of a problem to me: either your tire is good and it doesn't leak, or it's punctured and the in-hub pump is no use, or it's leaking slowly and you'll never know because the hub pumps it up constantly, but also steals your pedalling power in the process.

You never know what innovations like this lead to. It may look like a crazy idea but it could end up leading to a cure for........premature baldness!

There's always a catch, isn't there? Maybe you should have put this in the touring forum. They're the only ones I know of that could possibly rack up nearly 2 miles!!! a month.

I wonder if the valve hisses when it releases excess air. That would put me into a cold sweat hearing that and I would always wonder if it's the valve or a real puncture. I can see a real use for it with the casual couple-of-miles-after-dinner types.
