ERA
Our vision of what a carbon frame should be
ERA wasn’t born from a spec sheet or a marketing pitch.
It was born from a simple belief: a carbon frame must be more than a light and stiff assembly. It must deliver a true feeling. A natural, smooth, precise ride. A frame that reacts instantly when you push, that stays alive when you load it, and that inspires confidence every single moment.
A frame that works with you — not a frame that forces you to adapt to it.
From the very beginning, our goal was clear: find the perfect balance between precision, stiffness, and dynamic comfort.
This balance cannot be achieved with a single miracle idea. It comes from mastering every detail: the structure of the layup, fiber orientation, controlled flex zones, optimized volumes, seamless transitions… Everything that turns a carbon assembly into a true performance tool.
We spent months designing, analyzing, testing, starting over. Exploring layup combinations no one had considered. Shaping the forms until every curve, every reinforcement, every millimeter had a reason to exist.
This colossal work had one goal: create a frame that feels natural to ride, that accelerates effortlessly, that stays stable when things get fast, and that delivers stiffness — only where it truly improves performance.
ERA is that vision.
A frame that doesn’t seek to impress with numbers, but with the unique sensation it delivers the moment you roll onto the track.
Performance. Precision. Feel.
Welcome to the ERA.
A Long Development Process
From the first layup tests to the first laps on track
ERA wasn’t created in a single step. From the first prototypes and early layup validations in the factory, to the assembly checks with our team and the on-track testing with our riders, the frame evolved version after version until it delivered the exact ride behavior we were aiming for.
Mechanical Testing and Structural Validation
Before ever touching the track, every ERA prototype goes through an intensive testing phase at the factory.
These initial tests allow us to validate the layup choices, measure flex zones, analyze stress points, and refine the structure layer by layer.
This is where we confirm that the carbon architecture behaves exactly as intended—before moving on to real-world riding tests.
Quality control & prototypes assembly
Once the first prototypes are validated at the factory, it’s time for assembly.
Here, Michael Bias goes through every detail alongside our team: alignment, adjustments, perceived stiffness, rear-triangle behavior…
These real-world feedback sessions — carried out as close as possible to the product — are essential to confirm that the prototype delivers exactly the performance and the feel we’re aiming for with ERA.
First prototype
Two years after our very first sketches, here is the first rideable prototype:
the initial laps instantly validated our layup choices and set the foundation for ERA’s unique character.
Field tests & riders validation
It’s impossible to validate a frame without confronting it with real track conditions.
Our riders test ERA in extreme situations: explosive starts, heavy load turns, compressions, full-power sprints, and highly technical lines.
These on-track feedback sessions are essential — they fine-tune the frame’s behaviour until we reach the ideal balance between precision, stability, and riding feel.
First official race
First official outing at the European Cup: ERA secures a final with Michael Bias and Mathis Ragot Richard in the Elite category.
A first race that immediately confirms the frame’s potential at the highest level.
World Cup Baby
ERA was tested in extreme conditions during the UCI World Cup in Santiago del Estero, in the hands of Mathis Ragot Richard, our Elite rider and current European Champion.
A perfect proving ground to validate the frame at the highest international level.

DualYoke Architecture
The technical core of ERA
On ERA, the bottom bracket area is no longer just a mounting point.
It is the structural center around which the entire frame is built.
To master this critical zone, we developed a dual-support architecture:
- BBYoke, stabilizing the power base
- TopYoke, stiffening the entire rear triangle and ensuring structural alignment
Combined with our AXC Layup, this creates a uniform front-to-rear structure, where every zone works as intended, with no unnecessary over-stiffness.
Both Yokes work together to deliver controlled, predictable handling.
- Clean load management around the BB, with no unwanted deformation
- More consistent rear-end stiffness, essential for maintaining precision
- A calibrated vertical flex ensuring stability in all conditions
The goal was never to make ERA “stiff everywhere”, but to make it stiff only where it truly enhances performance — and to ensure natural, predictable, enjoyable handling.
ERA returns your power without harshness, stays stable under acceleration, and keeps a clear, predictable feel of the terrain.
DualYoke + AXC Layup
The balance between efficiency and control.
AXC Layup
ERA’s carbon engineering
The layup of a carbon frame is not just about choosing a fiber.
It’s the way every layer, every orientation, and every thickness work together that defines the bike’s personality.
With the AXC Layup (Advanced Composite Carbon), our goal was to deliver precise and natural handling:
- A layer structure designed to optimize the response of the front triangle
- A fiber distribution enabling safe, predictable and stable riding
- Strategic fiber orientations to maintain control without unnecessary stiffness
For ERA, we use a high-modulus Japanese carbon fiber, known for its consistency and its excellent stiffness-to-weight ratio. A true premium fiber, selected to deliver precise behavior and outstanding structural stability.
But it’s important to remember: the fiber alone doesn’t define the quality of a frame. Many focus on labels or numbers (T700, T800, etc.), while real performance comes from the global construction of the layup — the way layers overlap, intersect, support each other and interact.
The goal of the AXC Layup was never to make ERA “stiffer”. It was to determine where stiffness is beneficial — and where it should give way to controlled flex to preserve natural riding feel.
The result: a frame that behaves exactly as intended.
- A front triangle that responds instantly with no unwanted energy loss
- A central area (BB + Top Tube) reinforced for acceleration stability
- An upper structure capable of working vertically to improve dynamic comfort
The AXC Layup is not just a carbon recipe — it’s the signature feel of ERA: a blend of precision, control, and smoothness on the track.
Combined with the DualYoke architecture, it allows ERA to be reactive without being harsh, stable without being dull — efficient without sacrificing feel.
AXC Layup
Axial Dropouts & ADS System
Control, precision and adaptability
The dropouts of a frame play a major role in defining how a bike behaves.
With ERA, we wanted a solution that is stiff, simple, and designed for modern riding.
Axial Dropouts — 35 mm adjustment range
- A 35 mm adjustment range that allows you to set the wheelbase according to your riding style. We didn’t want to impose a fixed wheelbase — every rider is different.
- Integrated chain tensioner, simple and reliable, adjusted with standard hex keys
- Designed for a 15 mm axle (our preferred choice for stiffness and precision)
- Compatible with 10 mm thanks to our dedicated adapters
The Axial Dropouts were engineered to offer clean adjustment, consistent chain tension, and fast wheel removal in case of a puncture. No complicated mechanism, no alignment issues — everything was designed to be simple, robust, and efficient.
ADS — Adaptive Drive System
- Select your ideal wheelbase and keep it, regardless of your gear ratio
- Your gearing no longer dictates axle position: you always keep the same bike feel
- Perfect for top-level racing, where every millimeter matters in stability and precision
- Tyre change or puncture? The system ensures quick and consistent repositioning
- Fully optional: you choose whether you want to use it
With ADS, you choose your geometry — not your gear ratio.
The objective: a bike that keeps the exact same feel, from start to finish.
The combination of Axial Dropouts and the ADS System offers total control over chainstay length and wheelbase. It is a solution built for performance, repeatable handling, and ease of use.
Axial Dropouts + ADS System
Precise adjustment, full adaptability, and consistent handling — without compromise.
