Why We Like The Roubion Carbon R Mountain Bike
Positioned between the agile and playful Furtado and the big-hitting Nomad or Strega, the Juliana Roubion strikes a perfect balance for riders seeking a mixed-wheel bike that truly does everything well, and fast. Enduro racing, jumps, and gravity trails are well within its realm, but so are all-day pedal-fests deep in the mountains. That's why it's been a favorite of ours (and many other riders) since we threw a leg over the first generation way back in the day. Now in its fourth generation, the Roubion is an ultra-refined package as you expect from a modern Juliana, ready for you to build up your dream bike and hit the bike park or backcountry.
The fourth-generation Roubion has a frame that’s purpose-built to work around a 27.5in and 29in wheel combo, offering a better ride than scrappy mullet conversions that can have undesirable effects on the bike’s geometry and handling. The revised wheels bring the mixed wheel size game into the park and enduro lineup, giving riders a bike that's nimble in the corners but rolls over the chunder all day long. The bike maintains the same 150mm of VPP rear travel as the previous generation, but the suspension has lower anti-squat values to help enhance the bike’s traction and overall smoothness.
This Roubion also sees longer and slacker geometry, but Juliana didn’t go too crazy with it and the bike still has that agility that riders loved about the previous model. Our favorite change is the chainstay length that varies per size, ensuring every size of rider gets the same balanced geometry and fit. The reach and wheelbase are longer and the head tube is slacker, providing more stability during high-speed sections and technical descents. Juliana knows that pedaling prowess matters, so they incorporated a steeper 77.1-degree seat tube angle on a size medium to balance the long and slack geo. Combined with the efficient VPP platform, the bike tackles tough climbs with ease. The geometry is also adjustable via a flip-chip in the linkage, allowing you to tune the handling to suit the trail at hand.
Lucky for all of us, one thing that hasn't changed is Juliana's carbon frames, which is a good thing if you're after the legendary strength and unwavering stiffness of their renowned carbon layups. This particular Roubion benefits from the Carbon C layup, which uses a bit more material than CC frames but still accelerates quickly and offers unflappable poise when pummeling through rough terrain. It's backed by Juliana's excellent lifetime warranty, so you'll have extra peace of mind while riding particularly fast on your favorite stretch of trail and shuttling downhill laps on the mountain pass.
