The TRSr is the ultimate Enduro crank for 1x or 2x. Over the top thinking by the e*thirteen engineers resulted 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 the proprietary P3 Connect Polygon interface creates a more robust, reliable, impact-resistant spindle-arm junction. Spiderless chainrings shave grams and efficiently transfer power. The TRSr is intended for Enduro racing and general shredding.
