Been looking into cyclocross lately and its really peaked my interest. I'd love to get a new bike but just isn't in the budget. So I currently have a Specialized Sirrus Sport (2010) that I was hoping I could convert to a flat bar CX bike. Thinking of going from 3x8 to a 2x? cross crank and cassette and getting some CX tires. Other than changing the drive train is their anything else I would need or would it be more feasible to just go get a Jamis Nova Sport or a Kona Jake?
