I went to the local bike shop to look at a Navigator 2.0, but they were sold out in my size in the store and from the factory. We both learned that the Nav 2.0 was replaced by the Shift 2. They had 2 in stock at a different location. I went to the other store and compared it side by side with a Nav 2.0. The only noticeable differences were the 'sportier' frame lines(more like a mountain bike) and cleaner welds.....and the $50 increase in price....$549 ipo $499.
I went ahead and bought it and am very pleased so far. It's the Sparkling Silver 18.5".
