The Aethos Pro Ultegra Di2 is still one of the lightest road bikes we have ever reviewed on road.cc at just 6.66g. Specialized's S-Works model goes even lighter, with a 56cm frame weighing just 585g!
This build is now named the Aethos Expert (£7,250) with the Ultegra Di2 groupset and carbon fibre wheels, the current Pro comes with SRAM Force eTap AXS for £8,500.
Specialized's S-Works model goes even lighter with a 56cm frame weighing just 585g!
If you are not overly bothered about aerodynamics and just want minimal weight then Liam described this Aethos as the gold standard for general road bikes.
He found it to be a climber's dream with the way it floated up any sort of incline, and Specialized have also nailed the handling for when you are coming back down the hill, although the handling could be considered quite twitchy for some.
So, the price is high, but if you want one of the lightest mass-produced bikes on the market then the Aethos pretty much has you covered.
