Trek adds another level to its road range with the addition of the Madone 7 series. Unlike the luxury, barge of a car from BMW, Trek’s 7 series is very much a race-level machine.

With the current 6 series not only regarded as one of the best handling but also best balanced bikes on the market Trek has wisely opted to work on another angle for the new machine and so has targeted 2012’s buzz word – aerodynamics.

Working on the experience gained with the Speed Concept time trial bike the 7 series uses Kammtail tube shapes to reduce drag and still keep the frame profiles within the UCI’s mandated 3:1 ratio. Kammtail Virtual Foils work by mimicking the shape of an aerofoil but have the ‘tail’ removed, this is also known as a truncated aerofoil.

These slippery shapes have been built into the downtube, headtube, seatstays as well as the fork legs. If we are to believe Trek’s information the new shape saves 30 watts when compared to the 6 series when riding at 40kph.

Along with the new profiles Trek has worked with Shimano to help produce the new brake standard found on 9000 Dura-Ace. This new pillar mount makes for better braking but has also allowed Trek to move the brake to the chain stay and optimise the comfort of the seatstays – a common complaint on other truncated aerofoil frames.

Trek dealers are expecting to receive the first of the Madone 7 series in the forth quarter of 2012 with pricing currently set at £4,060 for an Ultegra-equipped bike through the Project One programme.

    30 watts??? Rubbish. I bet this notion was extrapolated from putting the frame in a wind tunnel rather than a bike and rider.
