Float Through The Hills

Why We Love It
The Aethos is the bike we have all dreamt about. No proprietary parts, so light it often sneaks under UCI standards, lightning fast and extremely responsive, while maintaining an incredibly comfortable ride. Specialized designed this bike with simplicity in mind, making it one of the most versatile road bikes on the market.
Upgrades
  • CeramicSpeed oversized rear pulley system installed to rear derailleur
Features
  • Ultralight climber with brilliant handling
  • Responsive and comfy geometry across terrains
  • Carbon layup creates a bike so light it frequently sneaks under UCI rules
  • Perfect balance of front and rear stiffness
  • Aerodynamics discarded in favor of outstanding ride quality
Master Mechanic’s Notes
  • New inner tubes
  • Light scratches on the fork, crank arms, drive side seat stay, handle bars & top tube
  • Please Note: Power meters are typically aftermarket upgrades, and we cannot guarantee functionality, battery life, accuracy, or calibration. Due to this, power meters are no longer factored into the pricing of our CPO bikes. Charge cables and/or spare batteries not included. In some cases, activation fees may apply. Contact our Ride Guides with any questions.
