I'm 5'10" (unlike cali I have shrunk an inch since I was a teen)

I have a 54" frame bike and my cranks are 175


Just of interest for you crank-ophiles, my partner is 6'3".
His TimeTrial bike is a 58" frame, and with his 83cm seat height (he has very long legs) he has had custom cranks made (which were cheaper to have made and delivered from America, than to have done locally).
185 cranks on his 58"TT frame.
