WTB (United States) - Press Release: The e-bike wheels you've been waiting for.
Specifically tailored to meet the demands of full power eMTBs, all aspects of WTB’s new HTZ wheels were meticulously designed to be the most dependable e-specific wheels on the market.
20% thicker rim walls:
HTZ i30 tubeless-ready rims boast an increased wall thickness of 20% over our already-burly KOM Tough enduro rims to help ensure they’re capable of withstanding the additional forces of modern eMTBs. We didn’t simply add material and call it good, though. Asymmetric spoke offset helps balance spoke length and tension to create a more stable wheel while a symmetric outer rim profile distributes impact forces evenly through the rim. HTZ rims also feature a vertical I-Beam support within the inner rim cavity to drastically increase the strength and rigidity of our toughest alloy rims.
Purpose-built e-bike hubs:
We increased the outer diameter of the rear axle sleeve from 15mm to 17mm to increase durability while remaining compatible with traditional 12mm thru-axles. This reduces axle flex while cornering and pedaling, which improves ride quality and bearing longevity. Double-stacked, sealed Enduro bearings at the inboard end of the driver body further improve durability and extend bearing life. HTZ hubs also feature a heat sink behind the 6-bolt rotor mount to dissipate heat up to 10% better on long descents.
HTZ hubs feature a heat-treated steel freehub body, which eliminates gouging and prevents pawl socket failure under load. The 6-pawl ratchet system provides simultaneous engagement of all pawls to distribute pedaling forces more evenly and improve durability on bikes with high-torque motors. Striking a balance between quick engagement and ultimate durability, HTZ hubs deliver 42 points of contact for 8.5° of engagement.
13-gauge butted spokes:
Wheel strength is limited by its weakest point, which is why the complete build spec is as meticulous as the component designs themselves. HTZ wheels feature 13-gauge butted (2.3/2.0mm) spokes that are oversized at the hub to increase wheel stiffness and durability, with the thickest section at the hub to counteract the higher braking forces and increased motor torque of an e-bike.
Mark Weir approved:
“E-bikes get you deeper, farther, and faster than a traditional bike. Having strong, durable parts is crucial to prevent getting stranded out in the woods. HTZ wheels give me the extra security and peace of mind I need when I’m deep in the pines.” - Mark Weir, godfather of American enduro and daily e-bike thrasher.
Hand-built in California:
Every HTZ wheel sold in North America is hand-built at our wheel building facility in California, while wheels sold in Europe are hand-built in Italy. Both facilities follow a six-step dewinding process to deliver equal spoke tension and worry-free riding. This process eliminates any winding stresses in the spokes that would otherwise release while riding. Combine this process with mechanically locking nipples and HTZ wheels will hold tension and stay true even through the most strenuous of rides.
