HTZ i30
USAGES: E-Bike
27.5” / 29”
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. Reliability is further improved by the
integration of WTB’s durable Solid Strip, which lies below the tubeless tape to cover the
spoke holes and provide a more dependable interface between the tire and rim. 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. HTZ hubs feature a heat sink behind the 6-bolt rotor mount to dissipate
heat up to 10% better on long descents. Cooler rotors increase braking power and
provide the rider with more confidence despite the extra weight of an e-bike.
