Great bike

Great bike both on and off road. It is very comfortable and handles well on rough trails. More than adequate power and battery for long trips.

Three Great Days

The day I found the Aethos Pro on the Sierra Bicycle Supply site and ordered the bike was the first great day. The second great day was when it arrived (Sierra did a great job of packing & shipping) and I assembled it,
and the third of many more was the day I took it out for a 32 mile shake down ride. Well,
I have been riding a Specialized Roubaix for the past 5 years and love the bike and will continue to ride it. The Aethos is in a category by itself, as I warmed up and started to crank up the watts, I was amazed at the fluidity of the ride. Using the same power as the Roubaix I found myself going 1.5 mph faster and the small hills we have here were all flattened out. What an incredible work of engineering, the geometry is so comfortable even in the drops I can't get enough time in the saddle. Absolutely a fantastic bike, light, responsive, smooth Di2 shifting what more could you ask for. Hats off to the designers at Specialized for creating a bike you dream about at a price point it is easy to live with.
