I can't add anything of substance to the crank length discussion but, can I have a beer anyway?

This one will have to be Dutch Treat. Not entrapment here nor a trick - meant just hopping on and noticing.
You and couldn't tell, right? In the longrun - few days'worth of pedaling, sure thing- we know what works best and sure, I'd not go with the longer track cranks on the slopes,rollers,etc. too much leg movement and as I said, who needs leverage when it gan be regained through gear development. The silly millimeters make a diff on the craters when coasting the straightkickers are not an option - and neither is the ride line in a scratch event .
Otherwise I'd make life and crank replacement easy by uing the universal fall-back- the 170. If this thread gets way intoit, someone will bring upthe 'scientific' article from bike World many moons ago that would suggest we be riding cranks from 170 to 225.
rubber-legged youngsters might make thgos work but leg extension differentials like that take tolls on the aging
