Been looking at Power meter crank arm. (Left)
I have the above crank set on my bike, is it hollowtech 2 and will any hollowtech 2 arm fit my crank? ie R7000 R5800 105 Ultegra Dura ace so long as same length (172.5mm)
I can’t find a definitive answer anywhere.
I have checked the shimano compatibility guide but still unsure
