 The Big Bang C9 MTB tandem is Duratec’s performance handrail 29er and is build specific for the latest 1x12 drivetrains.  Each C9 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 C9 tandem is built-to-order in the Duratec factory located just outside of Pilzen, Chech Republic.  Available in 11 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. 

Each C9 MTB tandem frame includes: headset, seat clamps, rear thru axle and replaceable rear derailleur hanger
