  • PACKAGE INCLUDES: 1x Crank Left Arm (170mm center to center, 198mm total length, 12.5mm front round hole & rear diamond hole).
  • IMPORTANT NOTE: Please check whether your right crank arm interface is square or diamond. Both left and right crank arms must match. Please confirm the crank length and connection interface before ordering.
  • WIDE APPLICATION: This Bike Left Crank Arm can be used for ordinary bikes, mountain bikes, road bikes, folding bikes, fixed-gear bikes, cross-country bikes, etc.
  • SUPERIOR QUALITY: BlueStars Bike Crank Left Arm is made of solid & strong Aluminum Alloy material, offering an excellent balance of lightweight performance and durability. Its fine polished finish resists corrosion and prevents color fading, while providing a stylish modern appearance. Precision forging ensures consistent strength, reliable pedal force transfer, and long-lasting performance for daily riding use.
  • EASY TO INSTALL: Our Left Crank Arm is well-engineered to ensure a precise fit to your bike and easy installation. They are also easy to clean and maintain in the long run. This crank arm is only suitable for the left bike pedal; it cannot be installed on the right pedal. Please pay attention to the left and right sides when installing.
  • INSTALLATION NOTE: If you have replaced the crank once, then you need to replace the bottom bracket when you update the crank again, because the life of the general bottom bracket is only 2 times. If you encounter any problems in the process of use, please let us know, we will be happy to assist you!
