Old Man Mountain and Axiom make racks for mounting to bike lacking eyelets and other mounting hardware. For my recent loaded tour on a road bike with no mounting hardware (no eyelets, etc.), I put an OMM front rack on my carbon fork -- in mounted onto the quickrelease and braced onto the carbon form. Used an axiom rear rack that mounted through the quick release and caliper brake mount. For folks with disc brakes, OMM has quite a few racks for mounting onto bikes with disc brakes. The mounting systems are very clever, and OMM was very helpful through email in helping me select and mount the proper rack.
