<p>This is JUST a prototype of an adapter that allows You to use disc brakes on old 3-speed sturmey archer internal gear hubs.<br/> Final part should be make from steel and welded to hub body.<br/> Hub shell is steel so it should'nt be hard to weld it even with basic stick welder.<br/> Bolt holes are standard metric M5.<br/> If You don't have tools to make it itself, 3d printed part will be very helpful for your local machinst as reference.</p> <h3>Print instructions</h3><p>No need for support.<br/> After print you'll need to "tap" or rather clean threads with M5 bolt.</p>
