[#12301846]

I am looking to purchase the below but I would like to swap out the FSA crnakset for a shimano 105 crankset so that I can use my power meter with it (a 4iiii one).

As it is a pressfit bottom bracket do I just need one of these and then can fit a normal 105 crankset. Thanks!

Yep

ps. I think the MegaExo one that came in the frame will almost-but-not-quite fit the Shimano - pretty sure the FSA has a step in the crank axle that makes them incompatible. But I'm happy to be corrected.

Yep, assuming it's a BB86 frame

Not familiar with the FSA cranks, would it not just be a straight swap without changing the BB?

Have a look at the Token Ninja BB. It's a little expensive (if you can find one) but it has loads of shims and also screws together in the middle so it doesn't creak at all
