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.

  • Our Ti drivers (pictured) shave off over an ounce of weight versus Chrome Moly.
  • Available in 9, 10, and 11 tooth versions, in both Left and Right Hand drive.
  • For 1/8" (9t) and 1/8" and 3/32" chain (10t and higher)

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*

**Cog, lockring, and spacer not included with cassette driver**
