Perfect for 1X!

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.

Great crankset!

The GRX cranks are perfect for gravel. Great quality, low gearing and low weight. It�s a trifecta!
