"Works as it should like all Shimano parts. I got the GRX rear changer to improve shifting on a wider range cassette than the Ultegra can usually handle."

"works primo. good cassette range"
Will wrap 11-42 with a 46/30 front
"Shimano quotes at 34t max cassette and a 40 tooth total capacity but they are wimps. I can cover a 42t cassette with a 46/30t front chainring combo without excess chain slack low.and AND room to go big big. Thats a 47 tooth capacity. Your results may vary, but definitely more capable than Shimano would claim."
