I have the plates and brakes mounted. I am going on front and rear. how should I run my lower cable? what have others done?I am running the 990 on the bottom of the seat stays, I have a cable guide in the center of the top tube, thought about doing a london mod but would rather run og style cables rather than 2 cables w/knarps. any suggestions? any one else done this? should I just drill my frame?
