Just used this as a replacement for the one that came on my bike, but was a 172.5. Works as it should. I am seeing significant fit benefits with the 165 crank. Much easier to maintain aero positions as top of the pedal stroke ends up being 1 1/2 cm lower in relation to your body once your saddle is adjusted.
On my last bike I previously used a Stages left side only PM. I bought a new bike which didn't have a power meter and did a bunch of research and decided on this 4iiii DA crank. I couldn't be happier with the purchase. I also took the opportunity to shorten the cranks to 165mm and switch to a 54-40 chainrings. I love everything about the new setup.
