Pin It Fancy


FSA's brand new range of high quality mountain bike cranksets are designed according to a fully-modular system. This means any rider or mechanic can easily, quickly, and safely swap out the spider, spindles, and chainrings from one set to another. It also features a built-in chain-line adjustment system so that wider Boost and traditional non-Boost configurations can each be accommodated with the same cranksets – so essentially one crankset works across any bike. The Modular system allows for the perfect combination of components, tailoring exact specification requirements to the individual rider and the type of terrain they're facing.

  • The spindle is a long 30mm type, which means that it's nearly compatible with all bottom bracket shell types; assuming that the buyer purchase separately, a 392 EVO bottom bracket made by FSA compatible with BOTH their crankset and frame. It is imand portant when choosing a bottom bracket, that the buyer understand, measure, and determine what type of bottom bracket shell they have. It a duty that must be performed by the buyer for their frame, to understand and measure their frame themselves to determine compatiiblity since they are in possession of the frame in question.
  • There is fundamentally not much of a difference between 10 or 11s chains. Chains widths are ultimately the deciding factor in determining compatibility of the remainder of the drivetrain. For this reason, it is important to understand that cranksets can be compatible either with 10 or 11s drivetrains.
