Just announced: a titanium version of the Jones Plus SWB, available in a diamond frame, space frame, and truss fork configurations!

Posted by Cass Gilbert

As with all ti bikes in the Jones range, builds are custom-select. There’s also a dizzying amount of options – be it the ti spaceframe (think springy), ti diamond frame (think bigger framebag space), ti truss fork (think light weight and precise handling), steel truss fork (think precise handling) or steel unicrown (think more affordable and lots of mounts).

If you dig the Jeff Jones geometry – you can read our full review of the Jones Complete here – you’ll likely dig this bike too. Numbers are exactly the same as per the SWB Complete and custom steel builds. We liked the $1800 Complete enough to include it in our recent 2019 Gear Awards… so expectations are high for a bike that is likely to end up costing four or five times that, when specced with matching top draw parts.

Note that the Spaceframe, which features lots of standover clearance, is available in a small, medium and large. The Diamond frame runs from medium to large.
