Niner JET 9 Carbon 4 Star X01 Bike

Though 29ers originally debuted as cross country bikes, Niner has taken the big wheeled bike and made it into a versatile, high performance trail machine. Capitalizing on the rolling efficiency of the 29” wheel, Niner designed the JET 9 to be more than just an efficient climber. Using their patented CVA suspension technology and their trail proven geometry, Niner was able to create a 29” bike that was not only efficient, but was also nimble enough to handle the endless rock sections, drops, and even the occasional jumps that can be found on most modern trails. The Jet 9 Carbon features the same geometry and handling characteristics as the Jet 9 RDO, blended with SRAMS’s legendary X01 drivetrain to deliver a formidable blend of simplicity and functionality.

The highly sought after X01 group brings SRAM’s 11 speed mountain drivetrain to the masses with a lower price point, without sacrificing performance. X01 is slightly heavier than XX1 (the difference is under 100g) but is still much lighter than any 2x10 setup out there, whilst still offering a wide gear range, thanks to the 10-42T X-Dome cassette. The new X01 cranks feature carbon arms and a removable spider (much like the X0 cranks) along with SRAM’s new X-Sync tooth profile which acts as a built in chain guide system. The rear derailleur’s X-Horizon design eliminates any vertical movement, reducing shift forces and preventing “ghost shifting”. The X01 drivetrain brings the latest and greatest SRAM technologies to your beautiful Niner JET 9 Carbon 4 Star bike, offering a simple, clean, and more importantly, reliable drivetrain.

The JET 9 frame is made from Niner’s highly durable carbon fiber that is backed by their 5 year, C5 warranty and is beautifully shaped and finished. The front end suspension is kept in the hands of SRAM with a RockShox PIKE RCT3 Solo Air 120mm fork with a 15mm axle, while the rear suspension is provided by a Fox Float CTD that features Fox’s CTD (Climb/Trail/Descent) adjustable suspension technology to deliver 100mm of smooth, plush, yet responsive travel.

This empowering unity of performance-driven components that augment the beauty and versatility of the JET 9 Carbon frame bring forth a bike that’s fast and lightweight enough to tackle a weekend cross country race, while maintaining the durability to survive bumpy trail adventures.
