Sonder Rubicon Gravel+ Adventure Bike

Building on their popular Camino all-roader, the new Sonder Rubicon is a titanium gravel-plus bike they call “the Goldilocks of mixed terrain.” Learn more about the UK brand’s latest model here…

New from Sonder Bikes in the UK, the Rubicon is a titanium gravel bike designed for taking on everything from weekend getaways to the Tour Divide. Using the brand’s award-winning Sonder Camino geometry as a starting point, the Rubicon features a slightly longer wheelbase, a slacker head angle, and a lower bottom bracket, all intended to deliver a more planted, confident ride that holds its line on rough terrain.

“Rubicon is the Goldilocks gravel bike that invites you to go further. It lets you enjoy pacy road sections and gives you uninterrupted play on more technical gravel,” said Sonder product designer Neil Sutton. A 60mm RockShox Rudy XL suspension fork and clearance for tires up to 55mm add comfort and control. The Rubicon sports 3D-printed UDH dropouts, full rack and fender compatibility, dropper routing, and several bottle and accessory mounts.
