Makes it real easy, and the larger diameter rotor up front offers great stopping power. I also bought a 49T sprocket for the rear wheel, and I use a 110 link chain.

You can use the same chain as long as you use the same size rear sprocket, but for dirt, you'll probably want 3 or 4 extra teeth in the rear.

What mirror is that?
