Amazing chainrings! Very well manufactured; the weight is decent, the tooth profile looks smooth and finished well, and not to mention that the shifting quality on these chainrings is amazing! I personally use a Dura Ace 9100 front derailleur, and when set up correctly, these shift flawlessly.

I bought these chainrings as I wanted slightly smaller gear combinations seeing as I do not race and since I personally happen to tackle hills that are usually more than 12% grade.
