By combining the speedy rollover of a 29er front wheel with the nimbleness of a 27. 5in out back the Juliana Roubion gives us the best handling characteristics of each wheel size. The Roubion has 150mm of finely-tuned VPP travel made to pair with a 160mm fork. This gives us enough travel to make it down any steep mountain trail but not so much to hold us back on big-mileage epic rides. Geometry-wise the bike is fairly long and slack with a 64. 5-degree head tube angle in the low flip-chip setting. This brings confidence at higher speeds but with a seat tube angle approaching 77-degrees the bike has a comfortable pedaling position to manage that slack front end. The Roubion frame uses Juliana's highest-grade carbon materials and layup known as Carbon CC. It saves roughly a 1/2lb of weight over the base-level Carbon C frames but offers the same degree of stiffness and strength thanks to Juliana's advanced carbon engineering expertise. The frame comes with a Super Deluxe Ultimate air shock which is the top offering in the RockShox lineup and features intuitive adjustments and a smooth consistent feel.
