The construction uses die-cast aluminum arms, a solution designed to ensure stiffness and durability in electric bike use. The \u003cstrong\u003e170 mm e-bike crankarms\u003c\/strong\u003e are a specific replacement for configurations that require this length and coupling standard.\u003c\/p\u003e\n\u003ch3\u003eISIS interface and compatibility with E-Bike motors\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eISIS Drive\u003c\/strong\u003e system defines the interface between the crankarm and the motor axle and must match the standard used by the drive unit installed on the bike. In addition to Bosch systems, the CK-220\/IS range is also indicated by FSA for specific Brose, Yamaha, and Avinox applications. The \u003cstrong\u003eBosch Gen4 crankarms\u003c\/strong\u003e must therefore be selected by checking both the ISIS interface and the length required by the original E-Bike setup.\u003c\/p\u003e\n\u003ch3\u003eDie-cast aluminum arms for E-Bike use\u003c\/h3\u003e\n\u003cp\u003eThe arms are made from \u003cstrong\u003edie-cast aluminum\u003c\/strong\u003e and feature a black finish with printed graphics. The 170 mm length determines the pedal stroke radius and must be maintained when replicating the bike's original setup. The \u003cstrong\u003e324-0054003230\u003c\/strong\u003e code precisely identifies this variant, distinguishing it from CK-220\/IS versions available in other crank lengths.\u003c\/p\u003e\n\u003ch3\u003eTechnical features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: pair of crankarms for electric bike.\u003c\/li\u003e\n\u003cli\u003eBrand: FSA - Full Speed Ahead.\u003c\/li\u003e\n\u003cli\u003eModel: CK-220\/IS.\u003c\/li\u003e\n\u003cli\u003eLength: \u003cstrong\u003e170 mm\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eAxle interface: ISIS.\u003c\/li\u003e\n\u003cli\u003eMaterial: die-cast aluminum.\u003c\/li\u003e\n\u003cli\u003eCompatibility: Bosch Gen4 and other E-Bike systems compatible with CK-220\/IS.\u003c\/li\u003e\n\u003cli\u003eMotors indicated by FSA for the range: Bosch, Brose, Yamaha, and Avinox.\u003c\/li\u003e\n\u003cli\u003eFinish: black with printed graphics.\u003c\/li\u003e\n\u003cli\u003eDiscipline: \u003cstrong\u003eE-Bike\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently asked questions about FSA CK-220\/IS 170 mm Crankarms\u003c\/h3\u003e\n\u003ch4\u003eAre they compatible with Bosch Gen4?\u003c\/h4\u003e\n\u003cp\u003eYes. The CK-220\/IS can be used as \u003cstrong\u003eBosch e-bike crankarms\u003c\/strong\u003e in Gen4 configurations compatible with the ISIS interface. However, it is still necessary to verify the specifications of the drive unit installed on the bike.\u003c\/p\u003e\n\u003ch4\u003eWhich interface do they use?\u003c\/h4\u003e\n\u003cp\u003eThe crankarms use the ISIS Drive standard.
