BSA, BB30, BB86, BB90, PressFit usw… Tretlager-Standards gibt wie Sand am Meer. Doch nun gibt es demnächst ein weiteres System auf dem Markt: BB386EVO. FSA hat dieses in Zusammenarbeit mit BH-Bikes entwickelt. Basis bildet ein 86,5mm Lagergehäuse mit einer 30mm Achse. Zielsetzung: Weniger Gewicht und höhere Steifigkeit. Dennoch hat das System schon jetzt einen Nachteil. Es wird bauartbedingt nur an Rennräder zum Einsatz kommen. Beim MTB sind mögliche kleine Kettenblätter, oder Lagerpunkt bei Full-Suspensions schlicht im Weg.
Dazu die Pressemeldung:
BB386EVO is wider, stiffer and interfaces with all current BB systems.
BH Bikes is known for developing cutting-edge products including the introduction of the first ever extended seat tube design, pioneering the development of sub-900 gram road frames and being one of the first to introduce aerodynamic profiles into road racing frames with its line of Global Concept frames that include the current G5, RC1 and Cristal designs. Recognizing another opportunity to deliver higher levels of performance, BH Bikes approached Full Speed Ahead with the idea of partnering to design a system that provides the platform required to develop substantially lighter and stiffer frames while evolving the advances already made in crank and bottom bracket designs to a whole new level.
The BB386EVO is the next evolution in frame and component design. Proposed by BH Bikes and developed in close partnership with Full Speed Ahead, the new BB386EVO system continues the evolution of the 30mm spindle standard with an eye towards expanded integration with frame manufacturers. With BH’s extensive knowledge of frame design and manufacturing, the new BB386EVO system integrates the benefits of oversized 30mm spindle designs into a new standard bottom bracket shell, which greatly enhances the performance characteristics. This BB386EVO design is an open source solution, available to all in the industry, to allow real performance gains by better integration of frame and component.
