The Specialized S-Works Aethos 2 Red AXS 2027 bicycle we’re featuring at Escapa represents the ultimate expression of lightweight road cycling. Designed without the constraints of professional racing and developed with a single goal in mind—to deliver the purest riding experience possible—this engineering masterpiece combines extraordinary lightness, unmatched ride quality, and an absolutely premium build.

With a frame weighing just 595 grams, the new S-Works Aethos 2 boasts the title of the world’s lightest mass-produced road bike frame, but its true greatness goes far beyond its weight. It’s a bike designed to become one with the rider, delivering unique sensations on every climb, descent, and turn.

The Lightest Frame Ever Created by Specialized

At the heart of this bike is the exclusive S-Works FACT 12r Carbon frame, developed using the revolutionary Flow State Design philosophy. Thanks to a supercomputer-assisted design process, Specialized was able to optimize every section of the frame to achieve the perfect balance between stiffness, compliance, and weight.

The result is a frame weighing just 595 grams, built with the most advanced carbon layup ever used by the brand. This spectacular figure allows for configurations under 6 kg—something unthinkable just a few years ago.

Evolved Geometry for Greater Performance and Comfort

The new generation of the Aethos further improves its performance thanks to optimized geometry based on data from more than 100,000 Body Geometry studies.

Key improvements include:

• A 15mm increase in stack height to reduce pressure on the neck, shoulders, and hands.
• A 7mm longer wheelbase to increase stability on fast descents.
• A steeper head tube angle to improve control and precision when cornering.
• A bottom bracket that’s 3 mm lower, improving the rider’s integration with the bike.

The result is an incredibly balanced, fast, and stable bike in any situation.

State-of-the-art SRAM RED AXS E1 groupset

The drivetrain features the exclusive SRAM RED AXS E1, the American brand’s most advanced wireless groupset, offering ultra-fast shifting, absolute precision, and flawless performance in any circumstance.

The drivetrain is rounded out with:

• SRAM RED AXS E1 12-speed rear derailleur.
• SRAM Red XG-1290 E1 10-33T cassette.
• SRAM Red AXS E1 crankset with integrated Quarq power meter.

A setup designed to deliver maximum performance on both mountain trails and Rapido terrain.
