Erik's got a new production fork called the Wampa for those of you who run or want to run fat tires such as the Surly Endomorph or Larry on your mtb or to juice up your current fatbike with a custom piece.
check that beefcake crown
It's available in 26 or 29'er configurations and because it's a Peacock Groove fork there's really no such thing as "production." It's available in any configuration you wish with whatever braze-ons you desire.
no indication of price, but I'm sure Erik will tell you if you ask him.
