FSA unveils its Vision Metron drivetrain group for TT bikes. This has been under testing with the Cofidis team last season. What is unique from the Vision Metron TT groupset is its new shifter design. The two levers on the aerobar extensions are the shifters. You no longer had to move your hand around so much when you shift gears as what you usually encounter with other barrel based shifting systems.
Inside the bars is a sliding rail mechanism. This ratchet system functions to index the gears when you press the integrated cap or the shifters. FSA also made sure that the entire system inside the extensions will generate lesser internal friction than other shifting systems.
The Vision Metron TT Shifter System also has the Vision TT crankset with BB30 omega axle, Vision front derailleur and carbon rear derailleur. They are currently compatible with SRAM/Shimano components.
