What if Specialized used every ounce of experience they\'ve gained serving riders over the past 46 years and built a bike made simply for the love of riding? Well.....The 2021 Specialized Aethos with SRAM Rival eTap AXS is designed to straddle the line between perfect ride quality, extreme lightweight, and undeniable style. The Aethos Comp model is no exception of any.The Specialized Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, subtly altering these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that they have perfected over multiple decades and you have the lightest frame out there.Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. We’ve also spec’d it with Roval’s all-new Alpinist carbon seatpost, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.KEY FEATURESFRAME:Aethos FACT 10R Carbon Fibre with Rider First Engineered™ Technology, Threaded BB, 12x 142mm thru-ale, Flat Mount Disc.FORK:FACT Carbon 12x100mm thru-axle, Flat Mount DiscCRANKSET:2021 SRAM Rival 12spd 48/35T , SRAM DUB BSA 68 Bottom Bracket.FRONT & REAR DERAILLEUR:2021 SRAM Rival eTap AXS 12-Speed Hydraulic Disc LeversWHEELSET:DT Swiss R470 24h Front and Rear
