Vision Metron Groupset

The 2017 Vision Metron Groupset is a high-end time trial or triathlete's group. Vision has delivered a high-performance drivetrain optimal for solo performances, including tri-bar shifters compatible with 10- or 11-speed gearing from Shimano or Vision, weighing in at a modest 138 grams, an 11-speed cassette in either classic tri 12-25 or a road-worthy 11-23, and lightweight, crisp-shifting derailleurs. The front is versatile and lightweight, and the rear's short cage is aerodynamically profiled, offering a modest speed increase of its own.
A good aero-bar compatible group.
