This has got me more excited than I should be. Willing to buy a fork just so I can have that wonderful mudguard.
Can’t find any info on them ,anyone know about them?

looks like a mocked-up pic of an sks one

I did something similar years ago on a fox 32 for the wife’s commuter. Araldite a bolt into the back of the arch and some stainless p clips around the fork leg. Forks have been sold, but I think we sti have the modified mud guards somewhere.
