Shimano Nexus DH-UR708-3D Centre Lock Disc Dynamo Hub

The Shimano DH-UR708-3D Dynamo hub employs a new internal unit construction that is lighter and also reduces dynamo
drag while producing 3 watts output. It is designed for Centre Lock disc brake wheels and uses a 15 x 100 mm E-Thru
axle design.

Technology

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.
