The Aethos 2 Expert Ultegra Di2 is built for experienced road riders who want the lightest, most responsive bike possible for climbs like Myra Canyon or long days out on Okanagan valley routes. It suits cyclists who already understand fit and performance and are looking for a race-calibre build with electronic shifting rather than an entry point into road cycling.
