Nice job TipoSerio, very discreet.
To my critical eye that discretion is completely ruined by the bag thing that sits underneath on the mudguard that sticks out like dogs balls.
BUT!, beauty is in the eye of the beholder. There is no accounting for taste, etc etc.

He did say to grind the tabs thinner (than the gap I'm guessing).
Just drill the hole bigger (12 or 13mm), grind them thinner and they’ll fit perfectly in the gap of the fork clamp.

He did say grind it down but unless the mount moves in the gap it is acting like a spacer, the moment it starts tightening up in the gap the grip on the fork can't get any tighter. Not a bad looking idea but how thin do you need to grind it down?
