These Disc Brackets are a takeoff from the normal Cruiser brackets available. They are still A50 Plate Steel, 3/8" thick and Laser cut to the tightest tolerances but they have a difference. All of the other Cruiser brackets we have seen use the tiny spacers or washers with an edge ground off, we take a different approach, and approach is the right word for this. Instead of having to make additional parts we put the bracket on the outside of the flange rather than the inside, the outside is flat and spacers aren't required to fit up tight. We bend them to bring them back to the correct position. We like bending, we are good at it and it is an inexpensive way to keep costs' down, and that keeps prices down for you. These are sold as left and right pairs. These brackets are a must for a disk brake conversion!
