    2021 S-Works Aethos Frameset

    For once, we’re not in it to win. With Aethos, we stopped worrying about winning, or the way things are supposed to be done, and instead chased the greatest expression of ride quality ever made. Well, we did it, and in staying true to keeping that promise, we broke every design, ride, and race rule along the way. And we’re not sorry. Aethos: Break the Rules.

    With this frameset, you have the perfect canvas to create the ride of your life.

    …oh yeah - it's light too

    …oh yeah - it's light too. If you follow most the press and the forums and the other things on the interwebs people are talking a lot about the weight and then about the price - in alternating order. This is the most fun and I'd say ""best"" bike I've ever owned and it's not because it's light. The uniqueness is how it feels on the ride: Compliant without being soft — playful but not nervous — elegant but extremely fast. The ride quality is exceptional. The bike is extremely comfortable to ride and the compliance adds traction which makes it an extremely confident descender. You can feel that you have more grip. The crazy things is that the compliance does not make the bike sluggish or soft when accelerating. The opposite: Putting down power almost feels like loading a spring that catapults you forward within milliseconds. I've ridden the bike with different wheel sets and can attribute this behavior clearly to the frame. The handling is quick but not nervous. The Geometry is essentially identical with the tarmac. This is NOT an endurance bike. It wants to go fast! And lastly: The bike is so much fun to ride. It feels light and elegant and quick and playful and is just a joy. …oh yeah - it's light too. All things considered the Tarmac is probably the faster bike (I've ridden the same climb on both bikes) and time and power were < 1% over 20 minutes and the Tarmac is more aero on the flat. But the Aethos is definitely more fun!

    Simply Amazing !

    I've blown a ton of cash on bikes, you name it Madone SLR, Colnago, etc...It was nice to come back to a light and quick bike. The compliance is amazing and the ride quality is superb. The Gloss Forest green is darker then whats depicted, but in the light the deep rich metallic colors just shine. I would equate the color to British racing green. Also the bottom bracket...thank god we are moving back to easier standards. This bike checks allot of boxes for me including cool factor.
