Specialized Aethos Frameset

The Aethos is built to prioritize pure ride quality and weight reduction above all else. By using advanced computational analysis to refine the carbon layup, Specialized created an ultralight frame that maintains structural integrity without the aggressive, race-focused geometry found in their Tarmac line.

Yes, the Aethos frameset offers clearance for tires up to 35mm wide. This allows you to set the bike up for rougher road surfaces or increased comfort without compromising the frame's performance.

No, the Aethos utilizes a standard threaded BSA bottom bracket. This is a welcome choice for many riders, as it simplifies maintenance and reduces the likelihood of creaking compared to press-fit alternatives.

Yes, the internal cable routing system is designed to accommodate both electronic and mechanical shifting setups. It provides a clean, clutter-free aesthetic regardless of which drivetrain you choose.

The inclusion of the SRAM Universal Derailleur Hanger (UDH) is a major benefit for long-term ownership. It is a standardized part that is widely available at most bike shops, making it much easier to source a replacement if you ever bend or break your hanger.

Rider First Engineering ensures that the frame's handling characteristics and stiffness are consistent across every size. Whether you ride the smallest or largest frame, the bike is engineered to feel equally lively and responsive.
