Paul Component Engineering Gino Light Mount Black CheckoutSpec= Ye The long thin tube isThe Gino Light Mount provides a mounting point for handlebar lights wherever there is an M5 threaded eyelet on your frame. With the Gino lights can be positioned at mid fork or down by the dropouts or attached to rack eyelets on the back of the frame. By lowering the attachment point of your light it casts its beam on the ground at a much shallower angle. This results in a lighting pattern that better reveals contours and hidden bumps in the road.
