Profile Racing's Cassette Drivers are what makes their cassette hubs so great. The 4 pawl design ensures that at least 2 pawls are engaged at all times.
This means that when you apply power to the pedals, it is instantly transformed into power at the rear wheel, unlike lesser hubs that take a quarter to a half a crank's worth of rotation to engage.
