The ROS 9+ is optional used as a single-speed bike or multi-speed bike and conveys with its fantastic 4130 Cro-Mo steel frame feel "Steel is Real". The shape of the frame material in accordance with the line and the form language of the SIR 9 and ROS 9, was again reinforced to withstand greater loads. The wheelset with the extra wide NoTubes Hugo Felgen and up to 3.0 inch tires provide more traction and comfort than its smaller brother.
The ultra-short chain stays (only 437 mm at 9 o'clock position of the bottom bracket) give the wheel an even better handling. The control tube is carried out in 44 mm oversize and takes it with tapered rigid or forks to 100 mm. By one of the MRP XCG mount fortified bash guard the rear sprocket can be protected from damage. The replaceable derailleur mounting the Breezer style dropouts and removable Direct Mount front derailleur open the way to ensure a clean look at the single-speed operation.
The bottom bracket system biocentric II Niner with only 100g the lightest eccentric bottom bracket system on the market. Apart from the low weight, the biocentric II has a much greater range of adjustment than other designs, resulting in an easy adjustment of the chain tension and allows the use of conventional dropouts. The framework also provides the ability height-adjustable seat posts with hidden control (Stealth) to build in.
The combination of wide tires and different driving options, the ROS is 9+ versatile. It can be spontaneously used as a single-speed racer to go the next moment with 30 courses in the Tansalp Challenge at the start. Who is not sure which setup is right for the use, can try out with the ROS 9+ all bike variants.
