I'm guessing a fork transplant from one bike to another with a shorter headtube. That way they'd be able to use the forks (albeit with a 1 1/8" to 1" converter) with an ahead setup, using the extra steerer length. Either that or they've got one hell of a lot of spacers on their existing threaded setup.
