Available in clincher and tubular with disc brake options available, Vision have made sure they'll fit your bike. With all new hubs and rim designs the new Metron 81 model features laser cut brake tracks on the rim brake models. These promise increased stopping power in all weathers without compromising on weight. Vision have also updated the hub design to utilise angular contact bearings which not only last longer but also respond better to lateral pressure produced via pedalling. The hubs are also compatible with both 10 and 11 speed Shimano and SRAM freehub designs, but have a new spoke lace design. A special 2:1 ratio on the rear wheel balances out the different tortional forces that a rear hub undergoes. With bladed spokes and external nipples the Vision Metron wheels are not only aero but also practical and easy to maintain.
