This style of sprocket is very innovative because it combines the brake drum into the design.
A drum brake is a very good choice of brake, and you'll be happy with it, especially when driving through water or other road hazards. The Combination works to shield the brake shoes so they work better than an exposed band brake.
The 72 tooth sprocket, combined with a 12 tooth sprocket won't be as fast as a 60 tooth sprocket, but should still clear 20 MPH.
