There will always be a lot to say about Eddy Merckx. He is regarded as the greatest road cyclist in history. With that type of pedigree, racing bikes with his name on the them are held to the highest standards. Here's the latest road race machine to bear the Cannibal's moniker, the EM525 Disc Performance.

There are two EM525 Discs available: Performance and Endurance. In addition to the differing geometries, the weight, stiffness and compliance also differ slightly.
For the Performance series, Merckx designs its bikes with four guiding principles. In order they are: geometry, it has to be an aerodynamic position; stiffness, for power transfer and handling; lightweight, for acceleration and climbing; and system integration, for clean lines.
The EM525 Disc will be offered as frameset and with three build kits: Ultegra, Ultegra Di2, and Dura-Ace Di2.

Oversize and aero
Moving down the bike, a seriously large diameter carbon down tube flows into the bottom bracket area. It's a BB86 press fit affair between the cranks, and it's surrounded by plenty of watt-channeling carbon aiming all your power at the chunky chainstays. From there, the kinked seatstays grabbed my attention. They are flat and give a nod at a modicum of compliance out back.
Taking a step back, the cleanliness of the design stands out. Beyond just the hidden Di2 wires and hydraulic brake hoses, the aero seatpost features an integrated clamp that's accessed from under the top tube. The top tube itself is curved upwards ever so slightly and arcs gracefully into the seatstays with their distinctive dog leg kink. Even those somewhat abrupt seatstay lines work nicely with the aero seat tube and its cutout for the rear wheel.
Up front, the fork has a bit of curve which tapers elegantly into the aforementioned massive lower head tube. No matter what angle you view it, the EM525 is a striking machine.
