Why put more than 40 in a harness "official" while there is the same thing for less than 10? The camera used is a Magicam AEE SD21, so that it can adapt I had to buy a loop but the whole remains below 10. This harness appears to be rather solid; the camera did not move after a bike crash at a speed greater than 40km / h. Look no further if you are looking for one.
