A Lightweight Tarmac from Germany

In Staufen, next to the hotel where Dr. Faustus was summoned by the Devil,
Frank Siebenhuener stands with his devilishly light Tarmac SL


I thought that my Specialized Tarmac E5 was lightweight but I hadn't seen anything until I lifted up this bike. My friend Frank, who lives in the Harz Mountains of Germany and is shown here in action in the Kaiserstuhl wine district in Baden, is a big fan of Specialized and has a Stumpjumper and a Tarmac. He is an equipment enthusiast and his Tarmac, when fitted with lightweight carbon wheels, clocks in at 5.9 kg (13 pounds), with pedals and bottle holders included. This is so astonishingly light that my Tarmac E5 feels bloated in comparison when you pick it up. The goal in building up this bike was not to spend limitless money but to build a serious roadgoing bicycle with reliable parts and excellent manners. In this he has succeeded but where can he go from here?
