I have some nitto dirt drop bars that look a bit like chippers (flared at the bottom) that came stock on my XO-2. The XO series were in some ways the first serious attempt to design a road bike with good offroad capabilities by combing road geometry with 26 inch wheels (there were no 29er tires available back in the day). It was a good design then and remains a good design. I like my nitto dirt drops a lot.
