From what I can gather Slide Away isnt a custom builder so much as a custom painter. There is no where on the page that talks about custom geometries or sizes, just about custom colors and graphics.

In the bicycle world there seems to be three different accepted definitions of custom. First is all mass manufactured components and frame put together personally. Second is a massed produced frame with one off paint and graphics, and third is a one off frame with unique sizing and geometry. All three definitions make sense, and no one is really trying to cheat any one by using one rather than the other(including Republic), it just gets confusing.
