Just bought a Falcon Interceptor bike with Shimano gears - whatever that means. I've had bikes in the past but only those with one set of gears for the rear wheel.
What's the need for front and rear gears? What should I be doing with them?
What are the front gears for? What should I be considering when selecting front gears and rear gears? Are they (front and rear gears) interdependent or independent?
