    Disc brake mount tabs

    Hi, I have an early 90's Trek 7000 aluminum frame and want to put disc brakes on the rear. Is there pre-made weld on mount tabs available for this or do I have to make my own? I have a welder that I work with and is an excellent aluminum welder. Thanks. Chris

    yes, i have seen it at CBO, but it might take some searching, also, u might want to triangulate the rear stays on that side, that bikes stays probably arent designed to take the added stress of a disc setup.

    You may want to put a post in the Frame Building forum, one of those guys can probably point you to a supplier and a good process for getting the placement and alignment right.

    My '94 Trek 7000 has a bonded aluminum frame. The dropouts appear to be bonded as well, but I don't know this for a fact. If your dropouts are bonded, I would expect welding in the area will destroy the adhesive bond and you will be in the market for a new frame.

    Thanks for all the help guys..also for the bonded frame issue!! That would be good to know..I was planning on stripping the frame and polishing it. So maybe I will look for another frame anyway. Chris
