EDDY MERCKX 525 Disc DuraAce

DESCRIPTION

Designed to excel at the highest levels of racing, the Eddy Merckx 525 Disc Road Frameset is a lightweight, all-around race bike with impressive aerodynamic performance and razor-sharp handling. It's sleeker, more aerodynamic, stiffer, and more cleanly integrated than the previous EM525 frame, but at the same time makes no sacrifices to ride quality or comfort. 

The 525 Disc Frameset is constructed from unidirectional high-modulus carbon fiber with a carefully planned out layup that bolsters stiffness in the bottom bracket and head tube junctions for efficient power transfer and precise handling. The front end stiffness is increased over the previous 525, yet the rear end is more compliant for a smooth ride over rough roads. The flattened and kinked seatstays may look a little strange to some, but they do serve a purpose, acting as a type of leaf spring to take the harshness out of battered chip-seal roads and unexpected potholes. The stays also join the seat tube lower down than the previous 525 to further improve compliance while increasing the aerodynamic gains.

The frontal area is reduced over the previous 525 for a more streamlined approach, and the fork crown transitions smoothly into the down tube to further cut down on drag. The frame includes an integrated bar and stem combo with fully internal cable routing, with the housing entering into the handlebar and passing directly into the frame for a clean cockpit with minimal drag. Other aero-optimized features include an integrated headset top cap for a smooth transition into the stem spacers, F-surface aero grooves on the seatpost, an aerodynamic gasket that covers the hidden seatpost clamp, and a seat tube shape that improves airflow around the rear tire.
