Hehe my bike and my homemade disk adaptor. Im not sure if i am selling it now, but what ever i do have i will deffo run the disk adapter, i did it for a little mess about, i feel confident that it will not break, after all it is 3mm steel which is held on by a 8mm axel. The only thing i could see might happen is the four bolt thread riping out, but i think it will be fine. In fact i trust the bracket more than the avid disk, as i have seen them snap across the bolt mounts (The caliper is cast). The brake works really really well, but i would like to try a more solid disk on the back like a hope mono trial or something as the avid caliper does flex on the braket. The Hope caliper is not cast like the avid i think it is machined which would help reduce the flkex and be much stronger overall i think.
