The Athena Power-Shift Triple 11 Speed Ergo Shifters from Campagnolo are a new set of commands with aluminium levers & a dedicated left control for triple speed cranksets. designed to shift a new & more efficient drivetrain. The Campagnolo engineers worked diligently to develop a new internal functionality & index pattern without altering the highly lauded ergonomic design of the Ergopower commands. The outcome, 2 clicks will now downshift from large to small chainring with a 3rd click for adjusting trim when using more extreme gears. This new design keeps the derailleur cage in a preventative position that avoids any possibility of chain dropping in addition to making for faster, more intuitive actuation of the drivetrain. The new system uses 3 clicks for upshifting without the need for an additional click for trim as the new SC-14 design allows for shifting across the entire cassette without any interference between chain & derailleur cage. The ''one lever-one action'' system remains as does the Ultra-Shift system, the only available mechanical shifting system that allows for multiple downshifts (up to three gears at a time in upshifting & 5 in downshifting).
