E Thirteen LG1 Crank Arms

A killer-looking, purpose-built DH crank strong enough for the most demanding riders. Over the top thinking by our engineers results in novel and innovative features that allow for lighter, stiffer, stronger and more reliable cranks.

30mm spindles provide a rigid base for the system while our proprietary P3 Connect Polygon interface creates a more robust, reliable, impact-resistant spindle-arm junction.

Primary Uses: Downhill and 4X race as well as bike park & freeride.
