The Merckx EMX-5 uses an advanced composite design with a 50HM/HS1K fiber combination mixed with Carbon Laminate+ for maximum strength and rigidity. It also uses Merckx's Optimized Structural Reinforcement (OSR) technology and aero seat stay design for optimal power transfer. To increase stiffness in the front triangle the Merckx EMX-5 uses a tapered head tube 1-1/8 inch to 1-1/2 inch along with an oversized BB-86 bottom bracket. The frameset retails for $3,800.
