Sorry, 11 speed Shimano. Basically the problem is the bike currently has a road crank on it but have had to shim the BB to get the arm to not rub the stays. Ideally I think an MTB crank would be better but would like a double. I have a road FD but don't think it would reach a 73mm crank.

I see you're running GRX 1x (with a RD-RX812 rear derailleur). I don't think you'll be able to run a double, because the rear derailleur doesn't have enough capacity for that.

So, I guess you're stuck with 1x. Unless you also plan to replace the rear derailleur.

I can change the rd, got the clutched rd that preceded grx spare. but am running the di2 supposed 1x version 2x without issue.
