Shimano Ultegra CS-R8000 11-28 11速飛輪

Shifting through the 11-28 is buttery smooth right out of the box, and the gear steps feel perfectly spaced for rolling hills. It clicked onto my Ultegra setup with zero fuss and the machining is visibly crisp.

The 11-28 range is perfect for my local climbs—I rarely need the 34 on the back anymore. After about 800km the shifting still feels tight and the steel cogs are holding up way better than my old aluminum ones did.

Shifting is crisp and quiet right out of the box—the 11-28 spread feels perfect for rolling hills without any gaps I notice. Weighs almost nothing compared to the old 105 I had, and it's held up through two wet centuries without a hint of skipping.
