Frame and fork are designed to work together – the much celebrated Jones Geometry. It's a bike without mechanical suspension. It's a "rigid" bike that isn't. It is not designed to run with a suspension fork and it does not need one.
The eccentric bottom bracket (EBB) allows you to adjust chain tension for single speeds and gear hubs, or to change your bottom bracket height to suit your preference for differing terrain or wheel sizes.
This frameset is all about function.
The 3D Spaceframe design was inspired by and born of riding on the tight, technical trails in the woods here in Southern Oregon, and each step in its development has been a functional refinement, so while some might speculate that the frame is supposed to look interesting, Jeff's only aim with the Spaceframe has always been to make a better bicycle. The frame's upper tubes are long, thin, braced, and curved in just the right way to allow them to flex and keep the bike vertically compliant; the downtube, chainstays and seat tube are oversized to keep the bike torsionally stiff. The low-slung top tube arrangement keeps the bike out of your way in technical terrain, so you can focus on riding.
