DT aerolite^® is the lightest flat spoke in the DT Swiss spoke range with excellent aerodynamic characteristics and a very high stability. The centre piece is first reduced and butted to a light 1.5 mm during the cold forging process and subsequently it is bladed. This process again increases the strength of the material and generates the flat shape. This spoke fits hubs with standard spoke holes.
