FSA’s brand new range of high quality mountain bike cranksets are designed according to a fully-modular system. This means that 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. This allows for Boost and traditional non-Boost configurations with the same cranksets. 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, and for when the time comes to renew and upgrade components. Compatibility with all current and future standards mean that the flexibility – and value – of FSA’s modular cranks is unparalleled and the benefits can be shared by all riders, future-proofing your ride.
