HTZ Freehub Kit

Pedaling a heavy e-bike up a steep, chunky fire road at a hard, steady cadence loads the freehub body on every stroke, and the WTB HTZ Freehub Kit replaces that part on WTB HTZ hubs with a heat-treated steel body that WTB says resists gouging and pawl socket failure. Its six pawls engage simultaneously, which spreads the combined torque of rider and motor across the whole ratchet system.

What Our Gearhead® Experts Are Saying:

“This kit is specific to WTB HTZ hubs at 12 x 148mm, so I confirm the hub family before ordering and then pick the standard that matches the cassette, HGR, XDR, or Micro Spline. On e-bikes, I replace the body as soon as the pedals start to slip under hard motor torque, since a body that slips there wears the pawl sockets further.”
