Quick Verdict
Yes – the Felt FR FRD Ultimate Dura-Ace Di2 is a true pro-level race bike. A 6.91 kg UHC Ultimate and TeXtreme carbon frame, Dura-Ace Di2 shifting and hydraulic disc brakes make it fast, stiff and light. The trade-off is a price of around $14,000, which is overkill for most hobby riders.
In the world of bicycles, there are many different manufacturers that cater to everyone’s needs. If you are into conquering rough and wavy mountain terrains, you go for a sturdy and reliable mountain bike, and if you are more of a leisure rider, enjoying the view while riding on flat surfaces, then a lightweight and affordable frame is one for you.
However, there is one bike that has caught our eye recently, the Felt FR FRD Ultimate Dura-Ace Di2 bike.
The name might be a mouthful but this bike really is something special. In this article, the specific characteristics of this bike will be covered, as well as some other important information and impressions that could help you in deciding whether this particular bicycle is for you.
Overview
The Bike Built for Racing
The first thing that everyone notices about this specific bike is its lightweight frame. By the way, the Felt company is famous as a manufacturer that favors quality, which can be seen in their road racing bike line.
The carbon frame, which is a UHC Ultimate and TeXtreme carbon fiber hybrid combination, is amazingly lightweight, and customizable tube sizes and a tube diameter that is steerer than before really help in achieving a smooth and steady ride.
This is a winning combination, as some of these carbon mixes are used on Formula 1 race cars and in the aerospace industry.Its geometry also boosts the biker’s performance. Both of these carbon types merged into a hybrid represent a good combination of stiffness and lightweight durability.
This frame is primarily aimed at professional bike riders and the ones whose main goal is competing at semi-professional or professional levels.
As for the aforementioned “biker’s performance boost”, it refers to the Shimano components that have been added to this model, which are said to optimize the rider’s energy due to the electronic shifting, keeping the fatigue consistently at bay.
The bike itself weighs no more than 15.2 pounds (6.91 kg), and with the aforementioned electronic shifting and great hydraulic disc brakes, uphill battles will be single-handedly won by every biker that opts in for the Ultimate Dura-Ace Di2 model of Felt bicycles.
As you can see, the name FRD is really justified by Felt’s commitment to details (FRD stands for “Felt Racing Development, in case you did not know).
The Lineup
Felt Road Bike Types
The FR FRD Ultimate Dura-Ace Di2 is the flagship of Felt’s road range. Here is where it sits next to the other Felt road bikes.
FR FRD Ultimate
The FRD (Felt Racing Development) models use Felt’s best UHC Ultimate carbon and top groupsets. They are built for racers who want the lightest, stiffest frame Felt makes.
FR Advanced
The FR Advanced models use the same race geometry with UHC Advanced carbon and Ultegra or 105 groupsets. They are a little heavier but cost far less.
AR Aero Bikes
Felt’s AR range is built for aerodynamics, with wind-cheating tube shapes and a lower, more aggressive position for fast flat roads and breakaways.
VR Endurance Bikes
The VR range has a more upright fit and room for wider tires, so it suits long rides, rough roads and riders who put comfort ahead of racing.
Build Quality
Components and Frames
Frames
The frame and fork are where most of this bike’s money goes, and it shows in the weight and stiffness.
UHC Ultimate + TeXtreme Carbon
The carbon frame, which is a UHC Ultimate and TeXtreme carbon fiber hybrid combination, is amazingly lightweight, and customizable tube sizes and a tube diameter that is steerer than before really help in achieving a smooth and steady ride.
This is a winning combination, as some of these carbon mixes are used on Formula 1 race cars and in the aerospace industry.Its geometry also boosts the biker’s performance. Both of these carbon types merged into a hybrid represent a good combination of stiffness and lightweight durability.
The FR FRD Ultimate Dura-Ace Di2 Bike Geometry boasts a lightweight frame that is designed for aerodynamic performance and road racing. The frame is constructed using a combination of UHC Ultimate and TeXtreme carbon fiber, which provides a balance between stiffness, strength, and weight.
Monocoque Construction
The monocoque construction of the frame ensures that it is both strong and lightweight. This construction technique involves molding the frame in one piece, which eliminates the need for joints and seams that can weaken the frame. The result is a frame that is both strong and lightweight.
The carbon frame of the FR FRD Ultimate Dura-Ace Di2 Bike Geometry is designed to be aerodynamic, which helps to reduce drag and improve speed. The frame geometry is also optimized for handling and comfort, which makes it ideal for long rides and road racing.
Fork
The fork of the FR FRD Ultimate Dura-Ace Di2 Bike Geometry is also constructed using UHC Ultimate and TeXtreme carbon fiber. This provides a lightweight and strong fork that is designed to complement the aerodynamic design of the frame.
The fork is also designed to provide a comfortable ride, which helps to reduce fatigue during long rides. The fork geometry is optimized for handling, which makes it easy to maneuver the bike around corners and through tight spaces.
Components
As for the Shimano components, the FR FRD Ultimate is equipped with a full Shimano Dura-Ace Di2 component kit, which is a groupset that enables quicker and smoother gear shifting.
Drivetrain
The FR FRD Ultimate Dura-Ace Di2 Bike Geometry features a Shimano Dura-Ace Di2 R9170 drivetrain. This electronic shifting system offers precise and smooth gear changes, making it a popular choice among professional cyclists.
The bike also comes with a Shimano Dura-Ace R9100 cassette, which provides a wide range of gear options to suit different riding conditions.
Now, this groupset has been equipped to other bicycle models, but this specific model’s lightweight and slender frame works well with the Shimano groupset, making it a great choice for professional racing or leisure speed ride, as this bike can reach amazing speed.
The Shimano groupset is a great upgrade to this model, as it offers the 11-speed cassettes that further simplify the bike gearings and smooths the shifting, as previously stated. You cannot go wrong with Shimano, especially when it is coupled with the Felt’s superior lightweight frame.
Brakes
The FR FRD Ultimate Dura-Ace Di2 Bike Geometry is equipped with Shimano Dura-Ace R9170 hydraulic disc brakes. These brakes provide reliable stopping power in all weather conditions, ensuring maximum safety for the rider.
The bike also features Flat Mount disc brakes, which provide a clean and streamlined appearance.
Wheels
The second characteristic important to all bike riders is the set of wheels, of course. The Ultimate Dura-Ace Di2 is equipped with Dura-Ace C40 wheels. The C40s are low-profile, have a carbon rim, are known to be highly aerodynamic on flat surfaces, and offer great control on flat steeps.
People who have ridden this bicycle have mentioned that the Dura-Ace Di2 model makes the bicycle itself behave more agile and reliable, while the wheels themselves come in different sizes, depending on the needs of the riders.
The available sizes are 36, 50, and 60mm, while the size 36 is the most popular and affordable size.
Tires
The bike comes with Continental Grand Prix 5000 TL tires, which are designed to work seamlessly with the Shimano wheels.
These tires are tubeless-ready and feature a 25mm width, providing a balance of speed, comfort, and grip. They also feature Continental’s Black Chili compound, which offers low rolling resistance and excellent grip in all weather conditions.
Ride Feel
Comfort and Performance
Comfort Features
This is a race bike, so comfort comes second to speed, but Felt has still made it easy to live with. The PRO Vibe Carbon cockpit and Prologo Dimension saddle are light and well shaped, and the carbon frame and fork take some of the buzz out of the road.
The tubeless 25mm tires help too. You can run them at slightly lower pressure than tubed tires for more grip and a smoother ride without losing much speed.
Performance Features
As for the aforementioned “biker’s performance boost”, it refers to the Shimano components that have been added to this model, which are said to optimize the rider’s energy due to the electronic shifting, keeping the fatigue consistently at bay.
The bike features a tapered head tube, which provides increased stiffness and stability at the front of the bike. This helps to improve handling and control, particularly when descending at high speeds.
There are several models of the FR FRD Ultimate Dura-Ace Di2 Bike, each with its own unique geometry. However, all models are designed with efficiency and climbing ability in mind. The bike’s gearing is optimized for climbing, with a wide range of gears to help riders tackle steep ascents.
The bike’s chassis is designed to be stiff and responsive, providing excellent power transfer and acceleration. The stays are also designed to be stiff, which helps to improve the bike’s efficiency and responsiveness.

Who It’s For
Who Is This Bike For?
While this bike can easily be considered to be one of the top bikes one can buy, you should really think twice before cashing out a large amount of cash for it, even though it comes in basically all sizes.
This bike does come with great components and parts but it is definitely worth it if you want to seriously commit to the sport, as its price tag stands out at around 14.000 dollars. It is definitely a great race bike but if you are an occasional rider or a hobbyist, this bike might be an overkill purchase for you.
However, if you just want to buy a reliable bike and simply ride and enjoy the vistas, the FR FRD Ultimate Dura-Ace Di2 bicycle will be underutilized in your care, but you can always choose another model from this line that will set you back less than the top tier model, as the cheaper model will provide you with reliability and enjoyment and everything else that should be a priority for a hobbyist bike rider.
So in a nutshell, if you are in dire need of an incredibly lightweight, stiff, and high-performing bike, go for the FR FRD Ultimate Dura-Ace Di2 model. On the other hand, if you are strapped for cash or need another piece of equipment for your hobby, think twice before buying this particular model and look at other cheaper and affordable models from the same FDR collection line.

Frequently Asked Questions
Quick answers to the questions riders ask most about the Felt FR FRD Ultimate Dura-Ace Di2.
Is Ultimate Dura-Ace Di2 good for mountain trails?
No, this model is specifically built for flat surfaces and should not be ridden on wild mountain trails, as it was specifically built to be ridden on flat surfaces, such as asphalt roads, and similar. If you are into mountain biking, this particular model is not for you. However, the Felt company has models for numerous conditions that you will find perfect for any situation if you want a model from this specific company.
I have heard the Dura-Ace Di2 is ultra-lightweight, is there anything special about this model?
This model is very lightweight due to its hybrid carbon frame, which is a combination of UHC Ultimate and TeXtreme carbon fibers. These are used on Formula 1 cars and in the aerospace industry, so you now know this lightweight frame is a big deal and expertly done with the rider’s comfort in mind.
I am in the market for a new bike, is this the right model for me?
This is a great model for anyone, however, the price tag is the first thing that will deter many from buying it. The second one is the fact that it is best used on flat surfaces, so forget about riding it on mountain trails or other uneven surfaces or bumpy roads, as it might be uncomfortable for the rider. This being the right model for you solely depends on your own needs, particularly whether you are ready to pay an exorbitant amount of money for a great bicycle and if you are planning on committing to the almost professional level of bike riding, and I cannot stress this enough, flat surfaces, like asphalt or concrete.
How much does the FR FRD Ultimate Dura-Ace Di2 weigh?
