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, 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.
Compatible with Profile Mini Hubs, Totem Hubs, High Flange hubs, Madera V2 Cassette Hubs, and Classic MTB Single Speed Hubs.
For 3/32" chain
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 (sold separately).
