Dura-Ace FD-R9100

The cage tension is spot on—no chain rub in the big ring, and shifts up front feel almost instant even under load. I’ve put about 300 miles on it and haven’t needed to touch the limit screws once.

Shifting is crisp and consistent, and the cage feels stiffer than the older model I had. Took a bit of fiddling to set up correctly, but once dialed in, it's been flawless on every ride.
