Published Jul 04, 2025 at 09:02 pmI took these chainrings in 50-34 to replace old models in 53-38 on a Shimano 10-speed group, no issues to report on the first rides. And as expected, perfectly compatible with Ultegra 8100 crankarms in 165cm that I took instead of my Dura-Ace 9000 172.5cm. (Translated review)
