Hellow I have a new magura louise 07 front discbrake on a koxx forxx, The thing is,the new ones are different,with the old ones the caliper was directly attached to the mounts of the fork, but with the 07 the caliper is different ,there is some sort of black thing,adapter between the caliper and the mounts of the fork. When i attached the brake to the fork but didn't tighten it fully,there is no disc rub,but as soon as i tighten the bolts it rubs.. Everything is brand new,so what could be the problem ? Thanx in advance stvn
