Just ordered the Winspace C5. Appreciate Ali tips on Shimano Groupsets

I just added a 2mm shim on the drivetrain side and it resolved the issue for me. The Magene has a different crankarm shape than Shimano plus a 1mm smaller Q factor makes it tight

Are you using 105 di2 FD? And how long or your crankarm?
 I've added 1mm shim to the drive side which didn't seem to fix anything. I played around with the app and am able to make it "just" work. But it's really really tight.
It on the very limit to rub on the outer plate of the front derailleur, but if I move the limit screw it will hit the crank. Therefore I don't really see how adding more shims fixes this problem?

Normal 105 12 spd derailer. I am using a 175mm crank arm, and after installing the crankI really had to take alot of time to fine tune my upper limit screw. You need to move both the crank and the FD out to fix the alignment difference with the smaller Q factor. Either way the space between the FD and the crank is scary slim, mine is less than credit card thickness

Ah okay, so it seems to be a general 12 spd shimano FD "issue" with this crank. Mine is just like that with creditcard thin spacing between upper limit and crank 

Also I noted about it seemed the chainring flexed when pushing in the right side pedal. However I took the crank off and tighten the lockring, and that was a bit loose. It looks like it has fixed the problem  Now I have no rub, but still scary close

Mine is very close as others have described (same again, 105 Di2 and P505) but after 7,000km there is no sign of rubbing.

Same experience here. The preload bolt came loose  During one of the early rides, but I just screwed it back on and there haven't been any issues since. I also see the smae flex but I wouldn't be confident in singling out any particular part as cause for it.

Overall very happy
