We made a trick little piece in order to use the best components from Raceface in our Krankedset. This adaptor threads into the flanged ACS freewheel on the KS and allows the drive side Raceface Cinch crank arm to drive the freewheel without any motor resistance. It also allows the rider pedal input to blend seamlessly with the motor input. Made in Canada out of high-grade stainless steel.
