Juego de brazo de cigüeñal con desplazamiento de 15 mm para Samox E3 BO Bosch GEN 2/Yamaha ISIS Info
The Samox E3 BO Bosch GEN 2/Yamaha ISIS 15mm Offset Crank Arm Set is a purpose-built replacement designed for e-bike drivetrains running Bosch GEN 2 or Yamaha ISIS mid-drive motors. The 15mm offset positions the chainring further outboard to improve chainline alignment — a critical detail on assisted bikes where drivetrain stress runs significantly higher than on conventional builds. Available in 165mm length, these crank arms suit riders who need a shorter stroke without sacrificing compatibility.
Samox has been producing OEM crank components for major manufacturers for decades, and that manufacturing background shows in the precision of the ISIS interface and the consistency of the finish. The 15mm offset is the key specification here — it's what separates this set from a standard replacement arm and makes it the correct choice for specific Bosch and Yamaha motor configurations where chainline would otherwise be compromised.
