Inertia Wheels Pro Disc Brake is likely a reference to a type of wheel for bicycles that is equipped with disc brakes. Disc brakes are a type of brake system that uses a rotor (the "disc") attached to the wheel hub, and a caliper that squeezes brake pads against the rotor to slow down or stop the bike.
Disc brakes are more powerful and reliable than traditional rim brakes, and are commonly used on mountain bikes, road bikes, and other high-performance bikes. They are especially useful in wet and muddy conditions, as the braking surface is less likely to become clogged with mud or other debris.
Inertia Wheels Pro Disc Brake wheels may be designed for specific types of riding, such as cross-country, downhill, or freeride. The exact features of these wheels will depend on the manufacturer and the intended use, but they may include features such as wider rims for increased stability, lightweight construction for improved acceleration, and durable construction to withstand the rigors of off-road riding.
