Eddy Merckx had teased us with the prospect of many new bikes on the way for 2019. But even a couple of months back, all we had glimpsed was new branding on bikes carried over from last year. Now while announcing the return to pro World Tour racing as the bike supplier of AG2R La Mondiale, an all-new 525 has been revealed as the team’s go-to, all-around aero road racing bike.

Just back at Eurobike we got a glimpse of the facelift to the Eddy Merckx bike brand since its consolidation by the Belgian Bicycle Factory group, with the first all-new bike for the brand – the Lavaredo 68 endurance road bike. But even then, the old EM 525 was shown painted up in the new look. Now the new flagship of the Eddy Merckx collection has been unveiled, and it looks to carry over much of the same lines as the original, now in a more sleek, more aero, and more integrated package.

Details remain thin on the all-new carbon 525 (note: it is no longer called the EM 525), but we can see plenty of evolution and a lot more integration over the current bike, raced mostly unchanged since 2012. In that time aerodynamics has come to dominate both one-day & stage racing. And Belgian Cycling Factory R&D engineer Toon Wils says the new 525 was optimized in their wind tunnel while still focusing on keeping weight low.
The new 525 still has the distinctive angular look of the previous Merckx bikes. That styling can be divisive, but the super thin, flattened & kinked seatsays promise a comfortable ride without compromising on control. The new bike even drops those stays a bit for even more flex and aero gains. Toon Wils says the new 525 has overall reduced frontal area vs. the previous 525, but increases front end stiffness for more precise handling and maintaining the comfortable rear end.
