The Metron 81 SL is FSA Vision’s Aero Time Trial focused wheelset. Vision’s complete Metron 81 wheel system features 24.3 mm wide, 81 mm deep section carbon tubular rims, direct pull bladed spokes, P.R.A. aluminium hubs with revised cnc machine bodies and durable ACB bearings with ceramic balls, ABS nipples, 2 to 1 lacing at the rear, CFD / wind tunnel proven aerodynamics, and pro-podiums over the last few seasons. These features make Metron 81 SL the top level of the vision wheel series.
After years of proving FSA Vision wheels strengths and durability at Paris Roubaix, the Metron 81 SL represents a signify cant step in Vision's understanding of wheel aerodynamics. Riders have long
understood that a deeper wheel is dramatically affected by side winds, and that riding in sidewinds is not uncommon. The Metron 81 handles those sidewinds better than any comparable wheels of this depth. This is achieved by an increased rim width in the area of the brake surface.
The Preload Reduction Assembly called system applies a preload to the hub bearings via threaded clamps. It provides a bearing adjustment without dismounting. Furthermore the revised hubs are featuring more durable ACB ceramic bearings (2 front, 4 rear), a larger drive-side flange and an increased flange width.
Ceramic bearings offer long durability, high resistance to vibration and a low noise generation.
