Just upgraded my Lauf Uthald's stock wheels and tires (DT Swiss e1800 23, Goodyear Eagle F1R) to ICAN Aero 40 II, Silca Protocol RCR.

800 grams lighter. So that's not nothing.

First carbon wheels on my first carbon bike. So I have little experience to compare with. But first ride went well. First thing I noticed was the sound. They kind of sing. I definitely noticed better cornering and smoother over small bumps and joints.

I am happy with my purchase.
