#1. Is Dura-Ace Di2 lighter than mechanical?

Ans: The weight difference between Dura-Ace Di2 and its mechanical counterparts is minimal, with Ultegra Di2 being only 80 grams heavier than mechanical Ultegra. Ultegra Di2 derailleurs appear slightly larger and bulkier compared to Dura-Ace models.

#2. Which is best Di2 vs eTap?

Ans: When comparing Di2 and eTap, SRAM Rival eTap AXS offers the advantage of compatibility with a wider range of frames due to its wireless nature. It can be used on externally routed frames, unlike 105 Di2.

However, using eTap requires having wheels with an XDR freehub body, which is less common compared to Shimano’s HG standard.


This upgrade kit stands as a top-tier choice for professional and serious cyclists seeking cutting-edge technology and enhanced performance.

With its Synchro Shift with customizable programming, riders can effortlessly synchronize front and rear shifting to suit their preferences. The enhanced Di2 functionality and wireless connectivity offer precise shifting and seamless integration.
