Das One 9 besteht aus demselben hochwertigen GX2 Scandium Rohrsatz wie der Multi-Speed Bruder Air 9 und liefert die hohen Leistungswerte durch fortschrittliche Materiallegierungen sowie den speziellen Rohwandmanipulationen von Hersteller. Ausgangspunkt unserer One 9 Entwicklung war das Ziel, das beste Single-Speed Bike zu bauen, das es gibt. Dazu gehörte der Wunsch nach einem extrem schnellen Bike mit hoher Tretlagersteifigkeit, das trotzdem einen angenehmen Fahreindruck vermitteln sollte. Mit der Unterstützung der Rohrherstellers Easton sollten wir diese Ziele erreichen: Hohe Schnelligkeit, Agilität und großen Fahrkomfort.
Als Ergänzung zum vorderen Rahmendreieck liefern die Ketten- und Sattelstreben mehr als nur gutes Aussehen. Die Rohre wurden individuell für die maximale Steifigkeit geformt, um gleichzeitig eine vertikale Nachgiebigkeit für den Komfort zu bieten. Abgerundet wird das Paket durch Niners eigenes Bio-Centric Innenlager-System, welches eine enorme Vereinfachung bei der Laufraddemontage mit Disc-Bremsen bietet und durch die variable Position des EBB-Innenlagergehäuses (hoch und niedrig) die optimale Abstimmung der Fahreigenschaften auf die Geländeform und die Vorlieben des Fahrers ermöglicht. |

Beim One 9 verschmelzen einer der technisch fortschrittlichsten Rahmen mit dem simplen Konzept eines Single-Speed-Bikes und der bewährten Niner Geometrie zu einem komplett neuen Fahrerlebnis: keine klappernde Kette, keine störende Gangschaltung, nur kindlicher Genuss in Reinstform.

No more creaks, no more rounded EBB shells, no more debate about which system is best. Niner’s new Bio-Centric bottom bracket system eliminates ALL of the issues with any eccentric bottom bracket system in an amazingly simple way: It’s a two piece design.
One of the Bio-Centric’s cups goes into the frame on the driveside of a normal 68mm EBB shell. The other goes into the frame on the non-drive side. There is an offset bolt that goes in from the non-drive side cup and threads into the drive side cup. The combination of this offset bolt, and the close tolerance of the Bio-Centric cup’s internal fit means that the threads for the bottom bracket line up automatically. Rotate one cup around the EBB shell, and the other will rotate with it, keeping the threads for the bottom bracket aligned. Any minor mis-alignment of these threads will be corrected once the bottom bracket and cranks are installed.
The final part of the puzzle, the one that solves all of the current EBB problems, are the flanges on the outside of the Bio-Centric’s cups. These flanges go ALL the way around the EBB shell, and clamp down against the side wall of the shell as the offset bolt is tightened. |

By using the sides of the shell to secure the EBB, Niner eliminates ANY possibility of rounding out the EBB shell, one of the plaguing problems of current EBB systems. In addition, by having 360° of contact around the EBB shell, the Bio-Centric’s cups SEAL the EBB from dirt and grime, which are the number one cause of creaking in other EBB systems. This seal also keeps moisture out of the system which is the key to noiseless EBB operation.
The Bio-Centric EBB has gone through over a year and a half of real world and simulated fatigue testing before we finalized the design, including a brutal CEN chain torque fatigue simulation test that put the Bio-Centric through it’s paces. The new EBB design went 100,000 cycles with no slipping or breakage.
Simple, light, and strong, we feel like the Bio-Centric is the perfect solution to chain tensioning needs. With one 6mm hex wrench, the EBB can be adjusted on the fly and in the field, and it’s still the lightest EBB system on the market.
Welcome to the new standard in EBB design, the Niner Bio-Centric EBB.
