The 5800 front design was flawed, the action was clunky and very hard to install. This product was a breeze to install and shifts great.
Built a bike with BB complete 105 R7000 components. Easy to install and adjust these components. Brought all the components from bike tire direct. Had to return one component due to the manufacture forgot to include a small part. Direct tire took care of it.
I got this to replace my old 5800 series 105 front derailleur. It is a vast improvement in all ways. Crisper shifting, easier adjustments on the limit screws, and a great additional feature that helps to visually confirm the proper cable tension.
I bought this to replace an older Shimano FD that had a protrusion on the top that got in the way of fenders.
It works perfectly, I never really have to think about it.
