Introducing the Felt FR FRD Ultimate Dura-Ace Di2. The Felt FRD (Felt Racing Development) bikes represent the top end of performance in the brand’s racing-focused lineup. As Felt’s flagship model, the FRD showcases Felt’s engineering capabilities for innovation by incorporating cutting-edge technologies and premium materials without compromising due to cost.
The FR FRD variant goes through Felt engineering’s most meticulous refinement as an uncompromising road racing bike, stripped of excess weight whilst attempting to maximise efficiency. During the frames development process Felt used wind tunnel testing and computational fluid dynamics analysis to optimise the aerodynamic profile, alongside structural assessments to maximise power transfer through finely tuned tube shaping and carbon layup processes.
This engineering effort equips the FR FRD to meet the demands of competitive riders and racers with podium ambitions. The components are selectively chosen to extract the best performance, while the hand-built frame encompasses the leading materials and construction methods available to produce an exceptional strength-to-weight ratio and ride quality.
The FR FRD is Felt’s answer of what becomes possible when conventions and constraints do not impede innovating for marginal, but meaningful, gains.

FRD Frameset Tech
Felt Racing Development (FRD) frames utilise advanced carbon fibre technology and manufacturing processes intended to optimise performance. Specific features include:
- Intricate carbon fibre layup patterns constructed from over 400 individual pieces to control frame stiffness, weight distribution and ride quality
- Incorporation of hollow EPS foam cores in the moulding process to improve frame structural alignment and consistency in weight, stiffness and vibration damping
- Use of high-quality carbon fibres and components from leading manufacturers, sometimes involving proprietary materials not found on other bikes
- Meticulous inspection and refinement of each frame by skilled craftsmen to meet stringent quality control standards
- Road and mountain frame options designed to deliver responsive, efficient and comfortable ride experiences
The FRD frame series exemplifies Felt’s commitment to innovation and pushing performance boundaries in cycling technology. The frames aim to provide exceptional capability through precise engineering and manufacturing techniques.
What is Carbon Fibre Layup?
Carbon fibre layup is the process of strategically arranging carbon fibre sheets or plies within a mould to create a strong, lightweight composite structure. This process is crucial in the manufacturing of high-performance bicycle frames, as it allows for precise control over the material’s properties, such as stiffness, strength, and vibration damping.
FRD frames can incorporate over 400 individual pieces of carbon fibre in their construction – more than twice the number used in other frames. Each ply is meticulously placed and oriented, ensuring that the material aligns with the specific stress and load paths within the frame. This meticulous process optimises the frame’s performance, balancing stiffness, weight distribution, and vibration dampening characteristics.
Engineers develop FRD frames in-house. The frames also utilise a unique hollow EPS foam core moulding process that adds time and cost. However, it enables tighter manufacturing tolerances for more precise structure alignment, consistent weight and stiffness, and an enhanced riding experience.
In contrast, non-FRD frames use a hand layup method with solid EPS core and silicone sleeve for shaping. This is a more standard carbon fibre moulding process.
The specific layup pattern varies depending on the frame’s intended use and the desired performance characteristics. For example, a race bike frame might utilise a more aggressive layup pattern, prioritising stiffness and power transfer, while a comfort-oriented endurance bike might employ a layup pattern that emphasises vibration damping and ride quality.

Road bike geometry is a complex topic that encompasses a wide range of factors influencing the bike’s handling, performance, and comfort. Here’s a simplified overview of some key aspects:
Head Tube Angle:
The head tube angle is the angle between the head tube and the horizontal ground. A steeper angle makes the bike more stable and less manoeuvrable, while a shallower angle makes it more responsive and nimble.
Seat Tube Angle:
The seat tube angle is the angle between the seat tube and the horizontal ground. A steeper angle makes the rider’s position more upright and comfortable, while a shallower angle makes it more aerodynamic and aggressive.
Reach:
Reach is the horizontal distance between the centre of the bottom bracket and the centre of the handlebars. A longer reach makes the riding position more stretched out and aggressive, while a shorter reach makes it more upright and comfortable.
Stack:
Stack is the vertical distance between the centre of the bottom bracket and the top of the head tube. A higher stack makes the riding position more upright and comfortable, while a lower stack makes it more aerodynamic and aggressive.
Wheelbase:
The wheelbase is the horizontal distance between the centres of the front and rear wheels. A longer wheelbase makes the bike more stable and less manoeuvrable, while a shorter wheelbase makes it more responsive and nimble.
In addition to these key dimensions, road bike geometry includes other factors such as chainstay length, fork rake, and tire clearance. These factors contribute to the bike’s handling, performance, and comfort, and can be adjusted to suit individual preferences and riding styles.
Examples of Geometry Effects:
- A steeper head tube angle enhances stability at high speeds but reduces manoeuvrability at lower speeds.
- A shallower head tube angle increases manoeuvrability and responsiveness but may reduce stability at high speeds.
- A longer reach improves aerodynamics but can be less comfortable for some riders.
- A shorter reach provides a more upright and comfortable position but may sacrifice aerodynamics.
- A longer wheelbase enhances stability but reduces responsiveness.
- A shorter wheelbase increases responsiveness but may decrease stability at high speeds.
In general, road bike geometry is a complex topic tailored to individual needs. The best way to find the right bike for you is to consult with a professional bike fitter who can assess your riding style and body shape and make recommendations based on your specific needs.
