The listed components correspond to the documented Roubion 4 CC X0 AXS Reserve build. Some components, particularly the fork, can vary by production configuration.
Carbon CC Frame
The Carbon CC designation represents Juliana's higher-grade carbon construction. The frame is engineered around aggressive trail riding, combining low weight with the stiffness and durability required for technical terrain.
Internal cable routing keeps the exterior clean, while the frame's geometry is designed specifically around the Roubion's long-travel suspension and mixed-wheel configuration.
150mm VPP Suspension
The Roubion uses Juliana's lower-link-mounted VPP suspension system with 150mm of rear travel. The VPP design uses two short links rotating in opposite directions to control the suspension's leverage characteristics through its travel.
The suspension platform is intended to provide a useful balance between:
- Pedaling efficiency
- Rear-wheel traction
- Small-bump sensitivity
- Mid-stroke support
- Downhill control
Combined with the 160mm fork, the Roubion is equipped for demanding terrain rather than being limited to lightweight cross-country use.
160mm Front Fork
The build is specified with either a RockShox Lyrik Ultimate or FOX 36 Float Factory fork, both providing 160mm of travel.
The generous front travel helps the bike maintain control through:
- Rock gardens
- Root sections
- Steep chutes
- Technical descents
- Drops and rough landings
- High-speed trail sections
SRAM X0 Eagle AXS T-Type Drivetrain
The SRAM X0 Eagle AXS T-Type 12-speed drivetrain provides wireless electronic shifting and a wide gear range.
The 10-52T cassette offers a low climbing gear for steep technical ascents, while the 32T chainring provides a practical gearing balance for aggressive trail riding.
Drivetrain Highlights
- SRAM X0 Eagle AXS T-Type rear derailleur
- SRAM AXS Pod Bridge controller
- 12-speed configuration
- 10-52T cassette
- 32T chainring
- SRAM X0 Eagle DUB T-Type crankset
- Wireless shifting
Reserve 30|HD Carbon Wheels
One of the defining features of the Reserve build is its carbon wheelset. The bike uses Reserve 30|HD rims with Industry Nine 1/1 hubs.
On Small and Medium frames, the wheel configuration is 29 inches at the front and 27.5 inches at the rear. This setup combines the rollover characteristics of a larger front wheel with the maneuverability of a smaller rear wheel.
The Reserve carbon wheels are particularly appropriate for riders who regularly encounter demanding terrain and want a premium wheelset without moving to a full 29-inch configuration.
SRAM Code Silver Stealth Brakes
The Roubion uses SRAM Code Silver Stealth hydraulic disc brakes with 200mm front and 180mm rear HS2 rotors.
The large rotors and four-piston Code braking system provide strong braking performance for steep trails and sustained descents.
The Stealth lever design also helps create a cleaner cockpit by bringing the brake hose closer to the handlebar.
Mixed-Wheel Design
The Roubion's wheel configuration varies according to frame size:
- XS: 27.5-inch front and rear
- S: 29-inch front / 27.5-inch rear
- M: 29-inch front / 27.5-inch rear
This allows smaller riders to use a fully 27.5-inch setup while larger frame sizes benefit from the rollover of a 29-inch front wheel without losing the quick handling of a 27.5-inch rear wheel.
Adjustable Geometry
An integrated Flip Chip allows the rider to choose between High and Low geometry settings. The Low position emphasizes stability and a lower center of gravity, while the High position provides additional bottom-bracket clearance and can be useful on technical climbs.
The Roubion platform has a slack head angle of approximately 64.5°, contributing to confident handling on steep terrain.
Glovebox Frame Storage
The frame incorporates Juliana's Glovebox storage compartment in the downtube. The system includes a Tool Wallet and Tube Purse, giving riders a dedicated place to carry essential trail equipment.
This integrated approach reduces the need for external storage bags while keeping basic tools and repair supplies accessible.
Dropper Seatpost
The OneUp V2 Dropper Post allows the rider to adjust saddle height from the handlebar. Lowering the saddle gives the rider greater freedom of movement when descending steep or technical terrain.
A dropper is especially useful for:
- Steep descents
- Technical switchbacks
- Rock gardens
- Jumps and drops
- Aggressive cornering
Recommended Applications
The Juliana Roubion 4 CC X0 AXS Reserve is designed for riders who regularly tackle:
- Aggressive trail riding
- Enduro
- Technical singletrack
- Alpine terrain
- Bike-park trails
- Steep descents
- Technical climbs
- Long backcountry rides
- High-speed trail sections
