WTB HTZ i30 front wheel

WTB proudly overbuilds e-specific products for those who couldn’t care less about weight but instead want components that stand up to the workload of e-bikes. HTZ wheels exceed the demands of e-bikers by delivering the most dependable e-bike wheel on the market.

Need an e-bike wheel that simply won’t let up? HTZ is for you. Every wall of an HTZ
rim is 25-30% thicker than those of our traditional alloy rims. HTZ hubs feature
a heat-treated steel freehub body with six pawls that simultaneously engage to
evenly distribute torsional forces while pedaling. We also increased the rear hub
axle sleeve outer diameter to 17mm (that’s 2mm thicker than a standard MTB hub)
while remaining compatible with all traditional 12mm thru-axles. This eliminates
axle flex, which improves ride quality and increases bearing longevity by reducing
angular load while cornering or pedaling. Speaking of bearings, we double-stacked
Enduro sealed bearings at the inboard end of the driver body to further increase
stiffness and extend bearing life. Lastly, HTZ hubs feature a heat sink attached
directly to the 6-bolt rotor mount to dissipate heat and reduce brake fade while
using oversize 220mm rotors.
