I really don't see the Adaptrac system catching on with regular riders. It weighs an extra 1 1/2lbs to inflate/deflate approximately 10 times(that's not a whole lot), costs money to recharge the tank, you'll have to go to the trouble of getting it recharged every ride. Is a few PSI change in traction/efficiency worth that to many riders? Downhillers ride lower pressure, all mountain guys go up and down more than 10 times/ride and aren't generally don't care about lap times anyway, and XC guys are the ones willing to spend stupid amounts of money to theoretically save a 1/2 second on their lap time, but they're REALLY sure the way to do that isn't training, but to spend thousands on losing 1lb from their bike, not gaining 1 1/2lbs on a tire pressure system.

But hey, what do I know. For some reason, like I said, people are willing to spend Thousands more for a bike due to maybe having 1 degree in frame geometry change and 1lb less weight. Road guys will spend thousands more on the exact same geometry bike and 1/2lb less weight. They'll be like Lance Armstrong, right? People do dumb s*** and there's definitely no shortage of people in our country with more money than sense, so maybe the Adaptrac system will be a big hit.
