engagement. It is approved for E-Bike and non E-Bike use and is available in black and silver.

Technology

Inter-8

The Inter-8 hub has increased its gear ratio to 307%, compared to 244% of the Inter-7 hub. The Inter-8 hub also
incorporates a closer gear ratio allowing a more efficient and comfortable pedaling cadence. A truly “all
conditions” internal hub has arrived.

Centre Lock

The Centre Lock system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring
mounting system reduces the total working hours by shortening the amount of time of both installation and
de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while
improving braking efficiency.
