WTB HTZ i30 Rear Wheel - 29" 12 x 148mm 6-Bolt Black Micro Spline 32H. HTZ i30 wheels are the perfect choice for your e-assist trail enduro or downhill bike; ready for more distance more laps more climbs and more descents. With all those “mores” also comes more weight continually bashing on the components of an e-bike. In order to overcome the increased forces induced by the technological progression of modern e-bikes WTB designed the HTZ wheels to be reliable sturdy and safe; keep riders rolling.

Capable of withstanding the forces of a modern e-bike HTZ rim walls are 25-30% thicker in comparison to those of standard rims

TCS 2.0 Tubeless ready for a dependable tubeless system

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

Double-stacked Enduro sealed bearings to further increase stiffness and extend bearing life

Heat-treated steel freehub body with six pawls that simultaneously engage to evenly distribute torsional forces while pedaling

Increased 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 improves ride quality and increases bearing longevity by reducing angular load while cornering or pedaling
