No. But, it's not needed for the Trucker. The Trucker uses thicker and heavier tubing. The ultra thin and ultra light steel tubing of other frames are heat treated. Surly has a philosophy of value for the customer. If they heat treated their frames, cost would go up. And I would imagine they would use thinner, lighter steel, but make the frame ride the same as now. So they just use thick steel, for longevity and value, and a plus with that is not having to heat treat. Surly are just simple, designed in US, made in Taiwan, frames that are tanks that just plain work.
