FSA’S NEWFLAGSHIP single-ring crankset is a great choice for powerful riders wanting to save weight.
The boxy hollow carbon arms with co-moulded spider and oversize 30mm axle are seriously stiff, no matter how hard you brace yourself against the bar and strain the pedals round. The BB392 axle/BB standard will fit BB30, PF30 and smaller diameter press-fit or threaded frames with the right adaptors. At a fraction over 450g, the K-Forces offer a big weight saving over most cranks too. The machined alloy chainrings use a unique ‘ABS’ bolt spacing, but FSA have a decent range of chainring sizes (30-36t). The subtly hooked, extended ‘Megatooth’ design is acceptably secure but beware of tooth-chipping boulder strikes. High performance equals a high price too.
