Found by Xterra triathlete stud Conrad Stoltz while lurking around Specialized HQ, this one-off carbon fiber tandem is based on Specialized’s 2010 SHIV time trial bike.
Made to be as aero as possible, everything that can be integrated is, including the computer, aero bars, brake and shifter cables and even the front drivetrain. The leader pedals a crankset linked to the stokers’ via an internal shaft drive.
There are a couple of other interesting tidbits worth noting: First, those are SRAM carbon deep V rims laced to Specialized’s Roval Rapid Star hubs (which, interestingly, are no longer shown on their website). Second, the Stoker has no brake levers.
More pics after the break…
Non-adjustable seat posts mean it better fit…or that it was made with specific riders in mind. Look how low the stoker’s face would be…
Fully integrated aero bars and computer, among other speedy touches, led Stoltz to dub this the “Supersonic Divorce Machine.”
The SHIV tandem uses disc brakes front and rear with hidden cables. Not sure if they’re hydraulic, which would mean some serious engineering to the brake levers, or cable actuated.
