The Jones bike is a bike for riding fast, slow, the rough with the smooth; safely, aggressively, laid-back or raging; with a big load or stripped to the bare essentials; on road, dirt, mud, snow; in the mountains, on the flat lands, around town or across the county; around the world or your local loop; for getting rad or just getting away.
The Plus SWB frameset can be built into a bike that is great bike for dirt, road, mountains, gravel, city, touring, trekking, bikepacking, commuting, fitness and adventure!
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.

Jones Titanium Plus SWB frameset available sizes and sizing:
Spaceframe is available in Small, Medium, Large
Diamond frame is available in Medium, Large
The fit and geometry for the Spaceframe and the Diamond frame are the same except the Spaceframe has lower top tubes with more stand over clearance.
See how the geometry and fit stay the same below.
This Spaceframe bike was built up with 27.5" x 3" tires on 56 mm wide rims and the Diamond frame bike was built up with 29 x 2.35" tires on 50 mm wide rims.
