Silca Titanium Derailleur Hanger

Today, I took my first ride using Silca's new 3D-printed titanium derailleur hanger. While I doubt it’s related, I had a slight speed improvement compared to all my rides on this route this year. What truly stood out was the exceptionally smooth shifting. While Dura-Ace Di2 derailleurs are renowned for their reliability, the enhanced stiffness of this hanger was noticeable, making shifting feel even faster and definitely more precise. I was initially unsure about this purchase, but now I'm convinced it has indeed elevated the overall quality of my ride. I suspect that the Di2's powerful motor performs more accurately with a stiffer hanger, resulting in more precise gear changes.
