Vision Metron 81 Clincher

The 2017 Vision Metron Clincher is a time-trial-focused road race wheel. Available individually or as a pair, both wheels sport sealed bearings, an 81-mm-deep carbon rim, and aero-bladed spokes. The front includes radial lacing; the rear is two-cross on the drive side. Hubs compatible with Shimano or Campagnolo drivetrains are available. While Vision recommends a wider tire for aerodynamic soundness, these wheels are perfectly capable of rolling on 23mm tires.
A very good aero road wheel.
