    Brake Interface

    The reason for the trend towards disc brakes is a question of safety: disc brakes improve control. But what are the differences between disc and rim brake systems?

    Net Weight

    Tolerance of the net weight indication +/- 15g.

    Rim Height

    In cycling, rim height significantly impacts the aerodynamics, agility and weight of the wheel. The general principle is the higher the profile of the rim, the greater the aerodynamic advantage; the lower the profile of the rim, the greater the response and better the handling when cornering and changing speed.

    Tire Interface

    Hooked or crotchet refers to the shape of the rim flange. In this variant, the rim flange has a so-called hook. This supports the fixation of the tire bead and ensures safe function, also in high pressure use cases (>5 bar tire pressure). Tubeless refers to the ability of the rim to be used without a tube, but a tube set up is also possible.

    Rim Inner Width

    Tires with different widths and profiles are used depending on the surface. The choice of tire width for the respective purpose in road cycling results in a recommendation for the rim inner width.
