Technology:
Center Lock:
- The center 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.
Power Modulator:
- As for the front roller brake, the braking POWER MODULATOR system is built in the hub side to ease sudden lever power input for easy and stable braking control.
