This time, we perform a comprehensive upgrade of the drivetrain on our beloved TIME ADH, installing the newly released SRAM FORCE E1 electronic shifting groupset. From unboxing analysis and spec selection, to removing the old RIVAL components and conducting precise per-part weight comparisons, every modification step is shown in detail. After assembly, we dive into setting up the Bonus Button auxiliary controls on the handlebar, and then hit the road for extreme testing of shifting smoothness and brake lever feel. What key changes do the shortened crank arms and the greatly improved hydraulic brakes bring to actual riding? The upgrade details are worth savoring.
