Specialized Aethos 2 Frameset (Nebula Metallic/Burnt Gold Metallic) (49cm)

Specialized Aethos 2 Frameset Description:

The Specialized Aethos 2 Frameset represents decades of effort spent by Specialized’s internal research and design team refining the profile and design of winning bicycles like Tarmac SL8, Crux, and the legendary Venge, granting riders access to the lightest production road frameset on the market and phenomenal ride quality to match. Advanced computational data observed with real-time analysis of air flow and frame loads led Specialized engineers to program Aethos 2 with an optimized carbon layup that adds material in layering stiffness, eliminating traditional “stiff” layers of carbon, resulting in a lighter frame weight with better ride quality, improved integrity, and feasible performance gains. Further weight reduction to the BB shell, brake mounts, and the institution of SRAM’s UDH derailleur interface leave Aethos 2 at a jaw-dropping 705g in the 56cm size. Aethos 2 boasts not only a lightweight and compliant ride but an accommodating fit that empowers all riders, regardless of bike size, with handling, stability, and comfort by way of an increased stack height. Aethos 2 strives to offer the “complete package” by furnishing room for tires up to 35mm in width, improving handling and comfort, and internal routing for a completely sleek look that appears as though it is moving when standing completely still.

Features:

• Lightest-in-class carbon fiber road bike with ultra-sleek aero-profile
• Flow State Design leaves Aethos 2 with tube shapes intended to channel optimized airflow
• Carbon layup, programmed with Flow State data, reduces material to improve ride quality and lower weight
• FACT 10r Frame/FACT 10r Fork exhibit premium ride qualities and render a minimal 705g on the scale (56cm)
• Rider First Engineering instills geometry that inspires versatility and confidence for all riders, regardless of bike size
• Roval Alpinst Carbon Seatpost acts with vertical compliance, issuing road-smoothening compliance
• Clearance for tires up to 35mm in width improves grip, speed, and compliance on rough roads
• SRAM universal derailleur hanger (UDH) furthers weight reduction and establishes compatibility with direct mount derailleurs
