NINER mountain bike frame 29 "ROS 9 Steel

The ROS 9 is optionally used as a single-speed bike or multi-speed bike and conveys with his fantastic 4130 Cro-Mo steel frame feel "Steel is Real". The mold in accordance with the line and the form language of the SIR 9, was again reinforced to withstand the frame material to gröÃ?erern loads.
The super short chainstays give the wheel an even better handling. The head tube is now carried out in 44 mm oversize and and take it with 120 to 140 mm forks on. Through a secured to the MRP XCG Up Bash Guard chainring can be protected from damage. The replaceable derailleur mounting the Breezer style dropouts and the removable Direct Mount front derailleur open the way to ensure a clean look at the single-speed operation.
The bottom bracket system biocentric II of Niner is only 100g the lightest eccentric bottom bracket system on the market. Apart from the low weight, has the biocentric II a much larger adjustment range than other designs, resulting in an easy adjustment of the chain tension and the use of conventional dropouts allows. The framework also provides the option adjustable seatpost with hidden control (Stealth) to obstruct.

The ROS 9 is versatile. It can be spontaneously used as a single-speed racer to 30-speed to go the next moment when Tansalp Challenge at the start. Who is not sure which setup is right for the use, can try with the ROS 9 all bike variants.
