When searching for an ideal solution for attaching my accessories I found this adapter. My idea was a solid second link rod with a diameter of 22mm and a length of 200 to 300mm. Since this adapter seemed to be the right of the description ago, I ordered the same 2 pieces. Not only that the quality convinces, also the material and appearance are unique. The range visible in the image outer "edge play" is fortunately not exist, but so far nothing makes me more than that, I have replaced the 2 short rods. The adapter I have the immediate right and left of the stem (32mm) mounted (Figure 1/5) and as an imaginary rod for motorcycles clip-ons from LSL (Louis, 280mm) used (pictures 2/5 and 3/5). Thus, the middle part is bridged, in whom I am mounted my front lamp. Links is a RAM-Mount (Hermann Mechatronics) for my Navi and the right of holders fitted for my Polaruhr (pictures 4/5 and 5/5). Corresponding pictures I have stored at the customer images.
(Because the clip-ons are only available in pairs, I have one left. If you are interested in a "replica" is welcome to report because of the price with me.)
