Felt launched the Nine series in 2008 specifically for those riding on roads with a lot of obstacles. To deal with obstacles on the road, it’s a rule of thumb that you need larger wheels.
However, the process of creating a new bike series is not as simple as just increasing the width of the wheel because it involves other factors including the geometry. To come up with the best models for riders, took the time and started from scratch.
Overall, the Nine series consists of bikes with larger tires, different front center, different head angle, and a special feature that helps keep the rear center short but still provides enough tire and front derailleur clearance.
Since we release the series, the Nine series has become a popular choice for endurance as well as races that last for a long time. Ultimately, this bike series is perfect for those who want a race bike, an all-rounder bicycle, or simply a bike to practice and improve their skills.
Benefits of Riding A Bike
There must be a reason why more and more people are adopting riding not just professionally but also as a regular outdoor activity, and it’s because riding a bike benefits you in a lot of ways.
- Riding improves your mental health with a study showing that riders get a 32% higher score in mental well-being than non-riders.
- Riding a bike also makes your immune system stronger as it boosts the production of important proteins in your body. Your upper respiratory system also becomes stronger.
- Many people have successfully lost weight as cycling helps burn about 400-1000 calories per hour.
- Riding is good for building muscles due to the resistance generated during the travel.
- Through riding, you will face a lower risk of cancers and heart diseases because it increases the heart rate and makes the blood pump better around the body.
- As a low-impact exercise, riding a bike is an efficient and safe activity for those with joint problems.
- Riding helps you sleep better. Researchers found that people with fewer fitness activities tend to have sleep problems more than those who exercise.
- Over the years, exercising in general and riding, in particular, has been linked to brain health. Thanks to cycling, the blood flow in your brain can rise by 28%, which helps you avoid dementia as you age.
So, what have we done with our Nine Series bikes to make sure you can get all of these benefits as a rider?
Which Components Stand Out?
Larger wheels mean better soaking up of obstacles. With this in mind, we chose to go with 29-inch wheels that naturally come with a shallower approach angle.
Compared with 26-inch wheels, the new ones do a better job in rolling over bumps, ruts, roots, and rocks on the way.
In addition, we increased the diameter of the bike wheels to achieve a greater gyroscopic effect. This, in turn, means the wheels can carry momentum better while the steering stability is enhanced.
When it comes to large riders, this fit issue is especially important as they find it harder to ride the typical 26-inch wheels.
If you consider the contact between the tire and the ground as well as the reduced fatigue resulting from smoother rides, you will see why it’s the right decision to choose our Nine series like many others have.
Building a new frame to fit the 29-inch wheels is not as simple as stretching the 26-inch frame.
In fact, the most important and basic thing to keep in mind is adjusting the front center and the head angle to make the steering trail match that of the 26-inch wheel. This is crucial for stability, and responsiveness.
The next key factor to take into account is the BB height, which has been reduced to match the 26-inch frame. At the same time, we keep the gravity center low while the handling is stable and ready to ride on trails.
The biggest challenge when designing the frame of the 29-inch wheel is keeping the rear center short and nice so that the front end remains lightweight.
Plus, the frame has to provide enough front and tire derailleur clearance. Our solution is using a specially curved seat tube along with a custom forged, CNC-machine chainstay yoke.
The Nine series features a steep head angle at 71.5 degrees along with 440m chainstays that keep the wheelbase short while keeping the steering sharp.
The geometry of the Nine series is designed to serve competitive racers and the large section bottom bracket, headtube, and chainstays are simply perfect for pace riding.
It requires hard and fast riding for the Nine to make sense. The stiff tube sections, as well as the wide bar, make sketchy technical sections easy as it should be for a 100mm travel race hardtail.
The bike also features Seatpost with a diameter of 27.2mm that makes it more comfortable for riders to sit for a long time.
In order to achieve these outstanding characteristics and rise above competitors, we relied on our own special technologies.
About The Applied Technologies
So far, aluminum alloy has proven itself an excellent material for constructing lightweight bicycle frames. Taking advantage of this outstanding characteristic, we utilize the most advanced forming techs.
These include Hydroforming, which uses high-pressure liquid and forms tubing from the inside out, which allows for complex and unusual external shapes while we can still use premium double-butted tubing internally.
As a result, we achieve lightweight, but incredibly strong tubing without needing reinforcement or gusseting. Besides, we tune the tubing directionally to create the desired ride characteristics.
Felt Active Stay Technology – FAST
This technology was developed to both meet the needs of world-class athletes and allow us to make an efficient, durable, easy-to-manufacture system using our existing technologies. It has three big benefits:
- Efficient pedaling: The technology relies on flexible carbons stays and anti-squat value. When the suspension moves from the sag point, a force is produced from either extending or compressing the stays, and it helps return the shock back to the sag. The result is a responsive, stable platform for you to pedal.
- Large impacts: The technology supports large impacts by reducing carbon flex and leverage ratio. As the leverage ratio lowers, it becomes more difficult to compress the suspension. Meanwhile, the carbon stays contribute an additional spring force when extended throughout the travel.
- Small-bump sensitivity: A smaller force is required to compress the shock. Besides, the linkage controls the large impact support and pedaling performance, so the shock can be run with the lowest compression damping. This means the shock remains active and can absorb even the tiniest bumps on the trail.
Carbon Fiber Technology
Carbon Fiber is an excellent material that’s lighter than aluminum but stronger than steel. It also allows for greater distributions where it’s needed and a smaller amount where it’s not.
All of our carbon frames are made using the Modular Monocoque Method, in which the chainstays, seat stays, and front triangles are molded individually. This way, we can optimize each frame section to meet different needs.

How To Choose:
Choosing the right size is one of the most important factors that will help you ensure performance, comfort, and safety as you ride.
You can buy the best bike in the world, but if it’s the wrong size, you won’t get a good riding experience or performance.
The choice of bike size must be based on the rider’s height and the rider’s inseam. We offer a detailed guide along with tables that show different dimensions suitable for different heights or riders. (https://feltbicycles.com/pages/bike-fit-calculator)
The best materials for making a bike frame are carbon fiber and aluminum.
- Aluminum: This material offers smooth rides and is generally more affordable.
- Carbon fiber: this material provides more comfort and vibration absorption than aluminum. But it also costs more than aluminum due to its manufacturing process. In exchange, you will get high-quality rides.
The wheels of a bike affect your overall experience in three ways: the bike’s weight, its acceleration and momentum, as well as wind handling, and aerodynamics.
In most cases, you cannot choose the wheels of your bike unless it’s a custom-made product.
However, you can look for larger wheels if you often ride on roads with a lot of obstacles or standard-sized wheels if you ride on smoother trails.
While basic bikes are sold with platform pedals featuring tose cages, high-end bikes often come without pedals. This way, you can choose a pedal system that you like and feel suits your needs the most.
Generally speaking, for pedaling efficiency, you should go with clip-in pedals and wear cycling shoes.
