I have a nice 2005 175mm crank arm with 53/39 chain rings SRM Pro power meter that I’d like to trade for a 50/34 compact crank version. I’d prefer to go with 170 or 172.5 crank arms but would consider 175s as well. I changed the power meter battery less than a year ago so that should be good for at least a couple of more years.
As I approach 60 my gradually reducing power output and aversion the mountain bike cassettes necessitates the change.
