I'm considering making some kits to convert a Girvin fork to be used with a fat tire. It would include new legs, and the parts necessary to move the legs out wider. The new legs would have a disc mount, 135mm spacing, and hopefully enough room for a 5" tire. NOTE: This would NOT be a lightweight kit! It will be made from 1 1/2 inch steel tubing. I estimate it would add about 3-4 pounds to the fork. I think I could sell the kits for about $150. I am trying to see how many people would want one of these kits if I made them. I would need enough people to make it worth going and buying a fork and doing the first conversion.
