Serious design attention in every section on the L1 yields a technological marvel that rides stiff, solid, and fast. The same frameset features found on the L-Series flaghip, L1R, are incorporated in the L1. The Quadrilateral System - an engineered box shape near the head tube - improves braking stiffness and resistance to torsional stress. BB386 technology stiffens the bottom bracket area and allows larger tubing to be bonded. Every cross-section of the frame is designed to make you faster.
