Argon 18 E-117+ Ultegra Di2
The draw: Ultra-adjustable
Since fit is the most important aspect of any bike, Argon 18 set out to make a super adjustable steed. Using head tube extenders, each size bike can have three different head tube heights to dial in the perfect fit. The optional top, rear and handlebar integrated storage units make it versatile for short- or long-course racing. The upgraded Vision Metron wheels (shown above), can do double duty for training and racing. The standard Vision Team 30 wheels are a better option if you already have your own race wheels, and drop the price to $6,300. For about half the price, you can get the E-117, a version that comes without the integration options and 105 components.
