Design criteria for the Nine has always been strict and focused. The goal is to combine the low rolling resistance of 29” wheels’ shallow approach angle with the higher gyroscopic effect of the larger wheel—while still maintaining the crisp handling characteristics of traditional 26” wheel bikes.
To maximize the Nine’s performance on the trail, Felt engineers modified the head angle and added a fork that produces the same trail as the Six Series. In addition, the Nine frames were constructed with same bottom bracket height as the Six bikes—lower than most other 29” wheel bikes to give it a low center of gravity and put the rider more in tune with the terrain.
The larger wheels did pose some formidable design challenges to Felt engineers. Chainstays on 29’’ wheel bikes frequently run long to accommodate the tire and front derailleur. But thanks to a curved seat tube and forged chainstay yoke on the aluminum frames, Felt engineers were able to keep the chainstays short without interfering with the front derailleur. This keeps rider weight properly distributed. Better front-to-rear weight distribution improves the bike’s abilities on out-of-the-saddle climbs.
The combination of all these features makes the Nine feel more like a traditional hardtail mountain bike, only faster. The result of all this engineering is a bike that inspires confidence with its tried-and-true handling.
Top Nine models feature Felt’s proprietary Dynamic Monocoque carbon fiber construction for improved ride quality, drivetrain efficiency, torsional rigidity and tire clearance. Naturally, a carbon fiber frame means the bike is lighter and offers a more comfortable ride as a result of carbon fiber’s natural damping ability.
The national-caliber marathon racers on the Kenda-Felt team will tell you: The Nine is an endurance racer’s dream. With its light weight and ability to float over rocks, it blends a smooth riding experience with incredible responsiveness. Its 29” wheels make longer off-road efforts more sustainable. Whether you are a seasoned marathon racer or weekend sport or recreational rider, there’s a Nine that’s tailor-made for you.
