FSA Afterburner Alloy M/Exo 386 X10 Crankset

FSA's 386 three-armed spider combined with top-flight aluminium manufacturing – that's the Afterburner Compact 386. By using three broad spider arms rather than four narrower ones, along with a smaller bolt circle, the Afterburner 386 delivers improved stiffness and a slightly narrower Q-factor and distinctive looks. The arms use the same high-tech hollow forging as other Afterburner cranksets, keeping weight down and stiffness up.
