Here's the Aethos Pro Ultegra Di2 - where Specialized have designed a road cycling bike which reinvents the classic road shape and delivers massive gains in stiffness and balance.

Specialized's Aethos Pro Ultegra Di2 is a premium road bike from the new Aethos stable, where frames and features found on traditional road bikes have been subtly altered to deliver ride quality and undeniable style.
