Big Bang R9 is a rim-brake, road tandem that is designed and built for racing. Each R9 is built with large-diameter 7020 T6 aluminum alloy tubes to ensure the rigidity and torsional stiffness required to produce a world class performance tandem frameset.
Each R9 tandem is built-to-order in the Duratec factory located just outside of Pilzen, Chech Republic. Available in 20 different sizes and 15 standard colors with custom geometry and paint available upon request.
Duratec tandems take 4 weeks to produce and ship via Federal Express or DHL directly from the factory in Czech Republic to authorized dealers and consumers across North America.
Optional painted-to-match front fork: The DURATEC FF02 Rim Brake R9 tandem fork is made of the same 7020 T6 aluminium alloy, weighs 720 grams and is fully certified for tandem use. The fork seamlessly blends with the headtube of the frame making for a beautiful overall aesthetic.
