Bold aggression.

Harness aggression into flat-out speed on the mountain with the Juliana Roubion 2.1 Carbon S Complete Mountain Bike. Purposely designed for aggressive styles of all-mountain riding and professional enduro racing, the Roubion demolishes chunky rock lines and rips alpine descents with unflappable composure. 150 millimeters of VPP travel smooths out the roughest terrain without flinching, making it an unstoppable force for all-mountain and enduro disciplines where larger rock gardens, steep descents, and bigger hits pose a significant challenge. Seeing that Juliana tailors their bikes for the needs of female rippers, you'll find the Roubion's tuned specifically for lighter riders with its female-specific shock tune. This makes it all the more sensitive when you're pedaling over roots and rocks standing in your way.

The second-gen Roubion is longer, slacker, and more aggressive than the predecessor, meaning it's far more stable and confident charging at higher speeds. This aggressive geometry makes the Roubion well suited for conquering demanding alpine terrain and rocky descents where short-travel bikes would be overwhelmed. The 66-degree head tube angle provides stability when you're opening it up at higher speeds and dropping into steep, rocky descents. The longer reach provides a roomy cockpit, so you're never cramped or uncomfortable riding the Roubion for long distances. Furthermore, the snappy 17-inch chainstays keep it quick turning and agile around tight switchbacks and sweeping berms.

This particular version of the Roubion gets Juliana's Carbon C frame, which provides high levels of stiffness and strength, transferring every pedal stroke into forward momentum. It's also incredibly tough, withstanding the regular thrashings you'll be subjecting this aggressive bike to. Internal cable routing cleans up its overall aesthetic while protecting cables from muck and trail grime. Another subtle, yet important feature is the threaded bottom bracket, which prevents the annoying creaks you're bound to encounter with a press fit bottom bracket.

The big story with the Roubion is the VPP suspension, which gets a revised architecture of the linkages for its third iteration. The third version of VPP attaches the upper linkage to the top tube, making it all the more stiff, as well as creating greater stand-over clearance for shorter riders. The bottom linkage is neatly tucked above the bottom bracket, protecting it from damaging rock strikes. These changes in VPP extend to the suspension's overall performance. For the third-gen VPP, you'll find it's more sensitive off-the-top when you're pedaling over rocks and roots. It's also more supportive through the mid-stroke, making it track consistently without the old version's tendency to wallow in the mid-stroke. As always, you'll find the VPP suspension ramps up considerably hard at end-stroke, preventing it from bottoming out harshly on bigger hits.

Looking at the Roubion's "S" build kit, you'll immediately notice it's equipped with SRAM's Eagle GX drivetrain, which provides a massive 500% gear range. This gear range is greater than what you'd find with a traditional 2x set-up, but without messing with a pesky front derailleur. And since this drivetrain is packing a massive 50-tooth bail-out cog, you'll have plentiful low-end for spinning up the steepest climbs without suffering in a higher gear. Other notable components include the Fox 36 Performance fork for stiff tracking over rough terrain (due to its 36-millimeter stanchions), as well as size-specific dropper posts, so you can get the most of this aggressive bike on the descent.
