Velo Senior Tech Editor Josh Ross has been testing the second-generation Aethos and explains what’s changed and how it performs out on the road. We also talk about that kinda mostly hidden cable routing, the advances in FEA software that allow more grams to be shaved, and the new Roval Alpinist CLX III wheels that use thermoplastic spokes with titanium ends. Fancy. 

Josh also compares the just-released Aethos to the previous version that we had at the Velo Field Test, and Levy forces him to decide between the Specialized and Scott Addict RC.
