Bought this for a 1x Lynskey GR300 build and it's got to be one of the best looking cranks out there. The look of a the 1x chainring and beefy crank arms just look indestructible. Besides looks, it has performed flawlessly for me.
Used a 1x11 40T crank with SRAM 1x11 group because the SRAM 1x11 crank ugly and prefer Shimano Hollowtech 2 axles. GRX 1x11 stock options are only 40T or 42T. In the end I used an older Shimano 5-bolt 110bcd crank with a brand that offers matching 1x rings ranging from 36T to 50T. Max versatility, not as slick looking, but always dirty when in use anyway. I would certainly use the GRX 2x11 cranks and keep the whole groupset GRX.
Bought this GRX crankset for gravel/ adventure riding. It have used XTR group set for mountain biking and have been very happy with Shimano durability and performance. The GRX components do not disappoint! Recommended.
