Profile Racing Chromo Cassette Drivers
Profile Racing’s Cassette Drivers are what makes our cassette hubs so great. Their 4 pawl design ensures that at least 2 pawls are engaged at all times, meaning 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.
Available in 8t – 18t
It is important to also replace your chain whenever you install a new driver. A worn, stretched chain will cause your driver to wear out much faster.
Pawls and springs not included
