Vision Metron 55-81 SL Carbon Clinchers

The Metron 55/81 SL is FSA Vision’s Aero Time Trial focused wheelset. Vision’s complete Metron 81 SL rear wheel system features 17mm internal wide, 81 mm deep section carbon clincher 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.

Vision's ultrafast and stable aero wheel developed through extensive CFD analysis and wind tunned testing. After years of proving FSA Vision wheels strengths and durability at Paris Roubaix, the Metron 55 SL front wheel represents the next step in their understanding 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 55 SL handles those sidewinds better than any comparable wheels of this depth.
