Roubion Carbon S Mountain Bike
For the third generation of Roubion, the savvy engineers and dedicated riders at Juliana decided to go back to the drawing board, aiming to make the bike more confident while hauling at face-melting speeds and better suited for lift-accessed bike parks. Realizing the need for a more aggressive bike, Juliana redesigned the Roubion Carbon S Complete Mountain Bike with a reconfigured VPP suspension inspired by the Strega: longer 160-millimeter fork, slacker head tube angle with an adjustable flip-chip, and longer reach measurements for a roomier cockpit and better composure on scorching-fast descents. The Carbon S model pairs the capable Roubion frame with SRAM's GX Eagle drivetrain and RaceFace wheels for a build that is ready to tackle that descent you've been eyeing all season.
One of the biggest changes to the third-gen Roubion lies in a longer, slacker geometry that pushes it deeper into the gravity end of the riding spectrum. However, this redesign doesn't significantly alter its all-around versatility, meaning it's still great for the rider that desires the monster truck plushness of a slack, long-travel rig while having fun on trail systems with big climbs and high-speed descents. Juliana lengthened the reach by approximately 15 millimeters per size for a more confident, comfortable feel at higher speeds, plus a centimeter lower standover height for a better fit with shorter riders. The head tube angle drops from the previous generation's already slack 66 degrees to an even slacker 65.4 degrees in its highest setting, complete with a flip-chip that slackens it out even further to a bike park-friendly 65.1 degrees. These were numbers that you'd only see on a freeride or mini-DH bike just a few years ago, meaning you'll have tons of confidence bombing those technical descents littered with steep drop-offs and nasty rock sections.
The Roubion enjoys the increased bump compliance and glued-to-the-trail traction you'll experience with a VPP suspension driven by a lower-link mounted shock that's inspired by the latest Nomad. This lower-link driven VPP suspension platform is something that's reserved exclusively for the Roubion and Strega, seeing the need for increased bump compliance, better support, and higher levels of traction for all-mountain, freeride, and downhill disciplines. To best match the increased performance capabilities of this lower-link driven VPP, Juliana spec'd a RockShox Super Deluxe shock for a more supple feel that tracks to the ground noticeably better and resists heating up on those scintillating descents over thousands of vertical feet.
The last major change implemented on the third-gen Roubion is the ability to clear massive 2.8-inch tires if you prefer the voluminous support of plus-sized tires. Juliana specs the Roubion with a 2.5-inch front Maxxis Minion DHF and slightly narrower 2.4-inch Maxxis Minion DHR in the rear for an optimal blend of rock-plowing traction, cornering support, and fast-rolling speed. This particular Roubion benefits from a Carbon C layup, which optimizes stiffness and strength, as well as reducing weight over cheaper alloy frames. The frame's impressive stiffness translates to precise handling when you're tossing it into a gnarlier rock gardens, as well as rapid acceleration the instant you place power to the pedals out of corners, up steep climbs, and from a dead stop.
One thing that hasn't changed for 2019 is Juliana's commitment to delivering an optimal fit and riding feel for smaller riders, thanks to a lighter shock tune. Available in sizes from extra-small to medium, the Roubion ensures balances handling across the size range, without compromise.
