The 2013 Trek Madone 7.0 Aero Road Bike Will Save You Two Minutes Off Your Best 60 Minute Time
In a sport where seconds can be your friend or your enemy, Trek's claim of saving 25 watts on the new 2013 Trek Madone compared to a similarly equipped bike without the aero changes is quite a statement. Not seconds, but minutes hang in the balance.Trek goes on to explain their statement in detail: "“We based the all-new Madone frame on our groundbreaking KVF (Kammtail Virtual Foil) tube shape. KVF minimizes drag using a truncated airfoil shape. The virtual tail of the airfoil bends to respond to the angle of the most common crosswinds, significantly reducing drag in the real world, where it really matters. It's like getting 25 free watts.”
Maybe you'd rather hear what an outsider and professional biike reviewer, Ron Koch at Bicycling Magazine, had to say about his test of the 2013 Trek Madone Aero Road Bike 7 Series:
I rode the bike in Belgium, just a few days before the Tour de France was set to roll out. We followed a 60-kilometer test loop that toured the hilly Ardennes region. The new Madone is a stiff, efficient race machine, even stiffer than the non-aero 2012 Madone—I couldn’t get this bike to flex at all, even when scaling a 20-percent grade on the famed Stockeu climb. Descents gave me the chance to take advantage of the bike’s crisp handling, which is just as sharp as you’d expect from a bike at this level. On rougher patches of pavement, and while passing over Belgian cobbles, the ride was very firm, but this may have had as much to do with Bontrager’s latest Aeolus carbon clincher wheels as the frame.

Slowtwitch did their normal fantastic visual shots of the new Trek Modone 7 series. Here is one example of the closeup shots they provided showing the Shimano Ultegra Di2 electronic shifting:
Trek waited to enter the Triathlon market until they could do it right, according to Trek themselves. This first entry into that market shows they have done their homework.

About Me
christania’s “cheap bike rentals” bikes are rolling across the city. The system, less than a year old, is funded by christania’s municipal government. It is currently only in one of christania’s 22 administrative districts. Although a 2nd generation system, there are 12 “Houses” in this district, each with around 40 bikes. The yearly subscription cost is the equivalent of $2 US, and allows the use of a bike for up to four hours at a time. In less than a year, there have been 6,000 subscriptions sold. There are larger 3rd generation systems in the world, which do not have a subscription to bike ratio as big as that.
