I just got a new Cross-Check frame which I am building up. The rear dropouts have adjusting screws for use with single speed/fixed hubs. My question is, if I'm using a freehub/rear derailer setup, is there a recommended setting for these screws? The frame came with the screws extended so that the rear axle sits almost all the way towards the open end of the dropout. I'm tempted to just remove the screws altogether so that I can just seat the axle all the way back and won't have to worry about one of the screws being set longer than the other and causing my rear wheel to be mounted crookedly. If I do this, does anyone have any suggestions for keeping the adjuster screw holes free of rust in case I want to use them later? I was thinking I could squirt some Frame Saver or Boeshield in there occasionally.
