PROFILE 4-PAWL 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.
Compatible with Profile Mini Hubs, Totem Hubs, High Flange hubs, Madera V2 Cassette Hubs, and Classic MTB Single Speed Hubs.
Cassette, 9, 10, and 11 tooth drivers can be used on both right and left hand drive hubs.
For 1/8\" (9t) and 1/8\" and 3/32\" chain (10t and higher)
Aluminum drivers (not pictured) are best suited for race use.
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)
