Hey!

I am buying a Scott CX Team from 2012 for some winter and gravel riding. I would like to put a power meter on it and I have a 4iiii single sided mounted to a Shimano 105 crank arm. The bike comes with Elita Truvativ crankarms and I want to change them for Shimano 105 crank arms with the current chainrings. I guess I would need to change the bottom bracket but is that it?
I'll post a picture of the crankset that is mounted on the bike today.

    Swap the crank arms and fit a new BB and that's it. You may also need to tweak the front mech setup, especially if you're changing ring sizes, but no other parts needed.

    That's great! Just what I wanted to hear :smile:

    I'm not sure that will work. Both 7000 and the older 5800 105 have 4 bolt cranks and the picture you have posted looks like there are 5 bolts on the current chainrings so they won't be compatible
