Direct replacement to Shimano rings on Shimano crankset
I purchased this chainring set for my Ultegra 6800 crankset hoping it would work, I was so pleased with the shifting performance I had to write a review. Yes, I understand, these are meant for the PES505 PM crankset but I used them on my older Ultegra crankset and they have worked so flawlessly I needed to post about my experience with these. First off they are so lightweight, definitely up to par with the OEM shimano rings. After installing, expecting front shifting issues, I was taken aback at how well and smoothly they shift, I couldn't tell they weren't OEM shimano rings. I would absolutely purchased again, they are pretty legit and deserve a try. Read more
