Amazing, Classic and timeless

The Rider's Bike. While it may not be for some, I truly enjoy the classic look of the Aethos combined with the modern build specs. I bought this bike to enjoy riding and get exercise. I dont race and likely never will. So I believe the Aethos is what 90% of us should be riding, if we are realistic with our performance. It's supremely comfortable and easy to work on. When trends fade this will still look just as good. Do yourself a favor and pick this bike up if you can swing the cost. You won't regret it.

Clean and simple!

Sold my Tarmac Pro SL4 after having it for almost 10 years. Purchased the new Aethos Pro and love the clean look with very little decals. Disc brakes and electronic shifting are a huge plus. The ride is a lot more comfortable than my old Tarmac. Climbing is noticeably easier too. Looking forward to a lot of rides in 2024!!!

Superb riding!

Lightweight and responsive, this comfortable Aethos rides and handles better than any bike I’ve ever tested or ridden. I’ve broken most of my Strava PRs since I got the bike after a tremendous amount of research. Definitely the bike for me (not a racer, just love to ride and climb - over 15,0000 miles/year).

Would Recommend?
Yes!
