Vision’s Metron 55 SL are the wheels you will ride once and won’t want to ride without again. This Metron 55 SL sits comfortably in the mid-range of Vision’s Metron rim depths, and offers the most versatility in the line up. This wheel climbs, descends, corners, and accelerates with the best of them. Vision’s complete wheel system features 24.3mm wide deep section carbon tubular rims, P.R.A. aluminium hubs with revised cnc machine bodies and durable ACB bearings, direct pull bladed spokes, ABS nipples, 2 to 1 lacing at the rear, CFD / wind tunnel proven aerodynamics, and 100+ pro-podiums over the last few seasons. These wheels are living proof that Vision wheels are among the best in the business.
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 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.
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 steel-bearings (2 front, 4 rear), a larger drive-side flange and an increased flange width.
