R7000 Cranks are the only ones I know of at 160mm. I have never seen left arms available separately, and the parts diagram does not even list a part number for the 160s.

You might have more luck seeking a 165mm left arm. I think I have a spare 6800 that I'd be happy to donate to the VA cause.

(doh, just re-read and saw you are after a drive side...)

Actually, the new R9200 and 8100 cranks are theoretically available in 160mm. The thing is, 165mm R8000 or equivalent level cranks are already pretty rare. They don’t come OEM except on the very smallest sizes. So I have no idea what the take up for 160mm cranks is going to be. And anyway who is even stocking the new cranks right now?

Thanks for your service..Might give Lennard a shout, he makes custom cranks in lengths down to 130mm..
