Smooth power transfer and balanced cadence for your e-bike

When the teeth on your old chainring start to wear, your drivetrain loses its sharp response and the chain can skip under load. This genuine Bosch 18-tooth front sprocket restores direct contact between your mid-drive motor and chain, delivering clean power transfer on every pedal stroke.  

• 18 teeth: Delivers comfortable gearing for swift daily commutes
• Wide compatibility: Fits Bosch Active Line, Performance Line, and Performance Line CX (BDU2XX)
• Durable steel: Built to handle heavy motor torque mile after mile  

Refresh your drivetrain setup and enjoy smooth power delivery on your next ride.
