In a world forcing the aerodynamic performance narrative, the Specialized Aethos is a breath of fresh air, eschewing the mainstream dropped seatstay and deep headtube configurations of contemporary road bikes for classic double-diamond architecture. The first-generation Aethos, launched in 2020, was a hit among purists and, in many ways, close to the best lightweight bike in terms of rider enjoyment – perhaps even perfect.
Specialized was careful not to lose those attributes with the new model, but was also keen to modernise the platform, which now gains an integrated cockpit, wider tyre clearances, subtle tweaks to the geometry and a carbon layup inspired by the S-Works Tarmac SL8 race bike.
Despite these alterations, the lightweight ethos and character of the original Aethos remain unchanged, as does the exorbitant sticker price of the S-Works derivative. As expected from a Halo bike, it gets all the bells and whistles, but is there anything to be gained or lost looking further down the range?
