FSA’s latest super-light hollow carbon crank arms now come in a universal four-arm spider configuration for habitual chainring changers – most of the K-Force Light range uses the company’s three-arm 386 chainset design that, while stiffer, is actually 50g heavier than the impressively light 576g conventional chainring setup here.
This one lets you choose replacement rings from SRAM, Shimano, Middleburn, Praxis and so on. There’s nothing wrong with the FSA rings, though, with compact 39/27T or 42/27T ring and bashguard options. Shifting is fine even if you’re digging deep on a climb, too. Underfoot stiffness from the broad hollow carbon arms and oversized alloy BB30 splined axle is more than good enough for the race brigade.
The captured 10mm Hex bolt makes installation easy, but make sure you take up any bearing slack with the preload collar rather than accidentally crushing them when installing. Apart from that, we’ve had great long-term results with FSA’s ceramic bearings in BB30 formats.
