I am building up a Fargo Ti (waiting on a few more parts to come in). I have a few questions concerning the build. A.) Do I need any Ti prep for the frame? I have heard that aluminum and titanium "cold weld" together. Is this true? Would any aluminum part that contacts the frame fuse together permanently? B.) Pretty sure I know the answer but can bb7 mtn brakes be modified for apex brifters? I'm thinking not but am interested to know if anyone has done it. I have built a few bikes before but I realize there is still a learning curve. Any one built up a Fargo ti I'm open to advice/opinions.
