Introducing the Bicycle Crank Arm, a top-quality replacement part for your bike. Specifically designed for both mountain and road bikes, this crank arm is a must-have for any cycling enthusiast looking to enhance their bike’s performance. With a length of 170mm, this left crank arm is made from premium aluminium alloy, ensuring durability and longevity.

The crank arm features a diamond square hole spindle interface type, so it is essential to check the orientation of your right crank before making a purchase. The hole spacing length is 170mm, which must match your original crank to ensure a perfect fit. The total length of the crank arm is 207mm, making it suitable for a wide range of bicycles.

The universal bike crank puller included with this crank arm makes it easy to remove or install square taper cranks, which is ideal for any home bike mechanic.
