Left Crank


  • Product Description

      If a crank bolt isn't tightened sufficiently, the crank arm can work loose. Since it's aluminium and the bottom bracket spindle is steel, the crank is quickly worn, and must be replaced (once it's worn you can't keep it on, even if you tighten the bolt).

      These left crank arms are great for getting your bike back on the road.

      Available in silver and black, and diamond and 90-degree orientation (if two sides of the square opening are parallel to the long axis of the crank, you need the 90-degree crank).
