Juliana Roubion

Ready to rally the World.

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 VPPĀ® 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 XS

More options for smaller riders.

Shock tune for lighterweight riders

Custom tunes that allow for more adjustability for lighterweight riders.

FAQS

Can I put a 27.5 front wheel on the Roubion?

These bikes are designed specifically to use mixed wheels. We do not recommend a 27.5 front wheel for geometry reasons. The XS size is the exception as it's designed for 27.5".

Do all sizes use MX wheels?

The XS size Roubion uses 27.5" wheels front and rear. All other sizes are MX

I see there are different chainstay lengths for each size bike. Can I buy a different swingarm to customize the length on my bike?

The chainstay length change occurs in the front triangles- we vary the pivot locations fore and aft to achieve the different lengths while using a single size swingarm. So no- you cannot get the chainstay length of the small on your size large, for instance.

I'm coming from a 27.5 bike- what will feel different with MX? Any setup tips?

An MX bike will definitely handle differently than a full 27.5 bike. The main difference you'll feel is a more stable and confident front end. The turning will be a bit slower than a 27.5, but the payoff is a more secure feeling in corners and more traction. Due to the taller front axle height and improved roll-over of the large wheel, your chances of stuffing the front wheel or going over the bars is vastly diminished. Use this security to ride challenging terrain with a more aggressive and dynamic body position.

I've been riding 29ers for a while- what will feel different with MX? Any setup tips?

29" bikes provide a ton of front wheel grip- this is partially due to the front wheel itself, but also due to the axle height of the rear wheel which works to keep the front end weighted. This creates a natural position on lower-angle terrain but requires body position and/or setup adjustments to achieve any sort of rearward bias.

On an MX bike, the bias is more rearward. This gives a very natural feeling on steep descents, but requires some body position and setup consideration for a balanced feel on flatter terrain. Compared to a 29er, a slightly lower handlebar and a more forward-biased suspension setup will make an MX bike feel more like what you're used to. Additionally, using the Hi BB setting will lend itself to a more front biased feel. Using these tuning parameters will help you find the sweet spot for your terrain and preference.

You'll know you have it dialed when it feels like you're never making large bodyweight shifts to either lift the front end or keep it stuck to the ground.

What fork offset is the recommended?

The Roubion comes with 42-44mm offset forks, and this is what we recommend for optimal handling. The size XS come with a 37mm offset 27.5" fork

What's the largest rear rotor that will fit on the Roubion?

The minimum is 180mm (direct mount) and the largest is 223mm

Why are there two different measurements listed for BB Drop?

BB drop is the measurement between the center of the bottom bracked and the front and rear axles. Because the Roubion (S-M) comes with two different wheel sizes the BB drop is greater up front.

Why MX (Mixed Wheels)?

Mixed wheels provide the stability and traction of a 29" front wheel with the agility of a 27.5" rear wheel. The smaller rear wheel and its comparatively lower axle height allows the rider to more easily unweight the front wheel- this makes for confident yet agile handling on the steepest of descents.
