Still figuring it all out. Im looking to replace my Shimano GRX 2x12 Crankset 31/38 Chainrings.

Was thinking about the EEWings, however I have come to the realisation that I m unable to get the hydraulic line and the EE Wing into the BB. It is just to tight. Any suggesstion on a different crankset. Main reason of why I want to change to GRX Crankset, is a complete Asthetic View. I massively dislike the look of the GRX Crank.

Any advice would be great.

Maybe this? A commenter said there's a far easier way to strip the anodizing, by dipping it in a chemical solution.

Whatever you do keep the original rings. I've tried a Rotor 48/31 combo and it can't shift from the small to big.

I'm running a Rotor Aldhu Carbon crank but it also requires a PM (P2M GX) to be able to use the Shimano 48/31 12-speed chainrings. I think an aftermarket spider exists (non Rotor branded) that allows you to run the Shimano rings with the Rotor cranks. But if you dislike the Shimano rings then your options are quite limited. Rotor does have cranks that have a 24mm spindle if your frame can't fit a 30mm spindle.

How about this?

Very expensive for the weight savings, but I have no issues at all with shifting using Rotor 48/31 rings. I'm running this on my recent crux build with Shimano Di2 12sp Dura Ace shifters & brakes, Grx 12sp FD & RD.
