On my Cube Attain Pro 2021 bike I have a Shimano Sora FC-R3000 crankset(175 mm - 50/34T).

Compatible with my budget, I'm planning on investing in a Stages Power Left power meter to get wattage data out of my rides.

My problem is which model from Stages to buy. I've checked their generic compatibility page which upon inspection technically it should be fine but I still don't know which exact model from Stages to go to. Yes, it will be a 175 mm one since that's my current crank length but since Sora isn't directly mentioned on their product listings which model should I buy?

Any Shimano road HollowTech II crank will work. Choose the cheapest in their line up which used to be 105, unless you plan to upgrade your group to (or upgrade to a bike with) EG Ultegra in the future and want parts to match visually.

The Road groups are Sora, Tiagra, 105, Ultegra, Dura-Ace.

The way in which the cranks are made and finished, along with the final weight, improves up through the range but the left hand arms remain interchangeable
