Reverse Arch Mudguard

I received this fender with my Machete. It looks promising but my 28×2.6 Maxxis Recons won't allow it to fit without major rub. Stamped on it is 2.6 max tire size. I'm assuming this is for 27.5 sizes. Sad that it was tossed back into the box with a bit of angst. Oh well. Looks good but functionless.

Why do you make forks this way and do not sell this mudguard in Europe? All shops I have found have no stock :(

Love the material it is made of....pliable so it doesn't crack when tweaked (looking at you Fox!). The pliability also lends to it backing well in a bike bag for trouble.

The challend is in the attachment interface. Not sure if it is the screws or the holes, but the screws strip before they get snug. When that happens, you have a floppy fender that you cannot remove. Not sure what to do about this thing.

I have a brand new R7 Pro that came with the guard, and it doesnt fit well.
The bolts got very tight in threads while the guard was still loose. Even after putting lots of effort into over tightening them, they still seemed loose, and there is a gap between the arch and the mud guard.
I also think the plastic is too soft and floppy, and finally cant fit 29x2.45 tyres on r7 Pro with the guard attached.

When are they going to make a mudguard or volume spacers for the Manitou Markhor fork ????????
