HTZ i35
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. Lastly, HTZ hubs feature a heat sink attached directly to the 6-bolt rotor
mount to dissipate heat and reduce brake fade while using oversized
