Santa Cruz Juliana Roubion 4 Carbon MX S Blue Medium
A 1:25000 scale map, a weather forecast and the Roubion. Three things you shouldn’t hit the high mountains without. And while we can’t guarantee you won’t get lost or soaked, we’re pretty sure there’s no better bike to tackle ancient alpine terrain. And whether blind racing or just blindly enjoying the trails as they come, the Roubion’s MX wheel combo feels like the best mix since Aperol met spritz. A 29-inch front wheel serves up high-speed stability and high-rolling confidence. Meanwhile the 27.5-inch rear makes for an intuitive and highly maneuverable rear end that loves to get sideways around the most ragged of switchbacks. This bike is rapid, so when it comes to stopping power and control we’ve mixed things up here also. A 200mm front and 180mm rear brake rotor pairing ensures you shouldn’t overcook the corners no matter how hot you’re coming in. The Roubion’s chainstay lengths are all specifically sized for the XS, S and M frames too, meaning handling remains consistent across the range. And like all Juliana’s, each shock is tuned to work better for slightly lighter riders than equivalent Santa Cruz models.
Travel for Days: 150mm of VPP® lower link rear travel and a 160mm fork
Best of Both Worlds: High-speed stability and confidence are fixed variables of the 29-inch front wheel, plus you get the 27.5 rear maneuverability for snappy moves, playing for style points, and negotiating hairy switchbacks.
Geometry to Match: The Roubion's chainstay length is matched to frame size so every rider, no matter their height, gets the same balanced geometry and bike fit.
Low Standover Height: Juliana's sloping top tubes always assures confdence for shorter legged riders.
Size X-Small: More options for smaller riders
Shock Tune for Lightweight Riders: Custom tunes that allow for more adjustability for lighterweight riders.

*In the bicycle industry, suppliers and factories sometimes change specs without notice and state that they are "subject to change without notice". This is because bicycles are made from hundreds of parts which come from dozens of vendors. Parts are sometimes updated to the most current production generation/iteration one gets better or more current parts or a comparable part. Product specifications are subject to change without notice.
