Taken off my DA SRM unit so they have been through their machining process to make them fit the SRM unit. These came with the SRM and I just had them swapped out for longer ones. Just the crank arms, no chain rings included. $250 shipped within continental US.

Are these 165 cranks still available.
I have a 170 cranks on my SRM. Can I just swap out my 170's on my SRM for these 165's and then do I need to send the unit back to SRM for recalibration?

These were sold.
I just had them swapped out for 175s and they had to recalibrate and replace battery anyways so I am not sure but I would guess they would say you need to recalibrate.

Definitely would need to recalibrate. Don't know how the strain gauge mechanism works, but given that torque = Fxd if you change d you'd want to know the change in torque then torquexRPM = power. Did you get the DA 165's from the SRM guys? Right now I am on 170 tapered square.
The 165s came with the SRM originally. I bought the 175S (brand new and never mounted) seperately and they machined them. I believe I was allowed to do this because they were out of 175 DA arms at the time.
