Are the current Jandd and Blackburn racks built for modern 135 mm spacing?
Also, are the Jandd and Blackburn designed to mount outside the eyelets, or inside? All of the Tubus racks seem to mount to the outside of the eyelets (the higher end racks appear to give more detailed specs). There is no way I could mount the racks inside on my current frame without interfering with the high gear cog and chain.
Mount outside the eyelets.
Most racks can flex to fit just about any width of frame. Just attach one side and then muscle the other into place. If you have a tandem width rear, you might want to be a little more careful
