Back in October of last year it was easy to find grx cranks, so I got two with 170 crank arms and 46/30 rings. Later, I decided to try 175mm crank arms and the 48/31 rings. A little Google searching worked to find those cranks online. You probably won't find any now.
I have knees from Johnson & Johnson.
