The future of high end frames and drivetrain component designs are being ushered in by FSA with the help of the new FSA 386 Evo bottom brackets.
What’s great about the new BB 386 EVO system is that it works well with the majority of the current bottom bracket standards, including the standard 68mm wide BBs for road bikes as well as a BB30 or a PF30 bottom bracket or even as a Bright system or a BB86.
As for the 386 EVo, this system is press fit and will sport an 86.5mm bottom bracket shell width, making the frame’s width wider and makes the axle as long as the external system with a total diameter of 30mm, similar to that of the BB30 system.
It is also because of this 30mm axle diameter that the bottom bracket system gets a higher stiffness-to-weight ratio. For increased stiffness and stability, the EVO’s bearings have also been placed farther apart compared to the BB30′s bearing positioning. The 386 EVO system also boasts of straighter crank arms giving more rigidity during runs.
No price has been announced for this new BB set.
