Question what is the difference between road bike and a cyclo-cross bike. Are the drivetrain components interchangeable and are they the same?
Answer The term "road bike" is generally used to describe a machine primarily built for racing.
A "cyclocross" bike is theoretically made for cyclocross (off road) racing.
Cyclocross bikes look like road bikes at first glance, but they usually have wider tires, and the frame has lots of clearance to permit the use of wider tires. For the sake of the wider tires, cyclocross frames have lots of room for wider tires, which "road" bikes generally don't.
Cyclocross bikes also generally have a wider range of gears, especially on the low end. Cyclocross bikes are very similar to touring bikes, and some models can't quite decide whether they're cyclocrossers or tourers.
