From what I understand. Not many of the original Fat team made thier way to NY to work for Serotta.
Several of the original Fat City employees started IF , Seven and several other frame builders. I heard as many as 13 companies (possibly more) spawned from Fat City Cycles.
At any rate, it's an incredible legacy. It's a shame MOST mtn bike companies don't have the passion, insight and pride that Chris Chance and Fat City had.
