If you still have a lot of cables, this is a must have. I still have a right shifter cable, 2 brake lines and a dropper cable. For you gucci riders who have the SRAM robots, you probably don't need this. For the rest of us poor folk, you will probably need this to keep the cables from causing a shadow on your handlebar light. It works great and seems to be pretty darn flexible. At first, it felt as though the amount of bending I was doing would break it but that is not the case. I wish it was presented more robustly at my time of purchase as I would have added it and would have saved on shipping. Maybe even a little discount at time of purchase. It is a really clean install on the headlight with the supplied screw.
