WTB HTZ i30 TCS 3.0 RimPerfect for off-road riding, this high-quality electric bike (E-bike) rim features 4D angled spoke drilling, which eliminates binding and lateral loading, and disperses tension more evenly over a greater area. Ready for hitting the trails, this model's symmetric outer profile offers equal dissipation of impact forces on both sides, while its asymmetric spoke hole drilling allows for even spoke tension and increased wheel strength.Durable, Thick Walled RimE-bikes add to the riding experience by simply providing more for less. 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 its HTZ rims with more material in every area of the rim prole. Every wall of the rim is 25-30% thicker in comparison to those on WTB's standard rims, which WTB then paired with its proven I-Beam centre support to ensure no beating was too great for these rims. All HTZ rims are TCS 2.0 tubeless, feature asymmetrical spoke drilling, and are available in widths ranging from i23 to i35 in order to provide options for e-bikes ranging from e-assist gravel bikes to dual-crown downhill bikes that no longer need a truck to be shuttled.Tubeless Ready E-Bike RimTCS 2.0 Tubeless ready and comes with a preinstalled Solid Strip, which lies beneath the tubeless tape and prevents sagging at the spoke holes, creating a smooth interface between the rim and tire bead. This prevents air from escaping around the bead and therefore requires less air volume and pressure to mount a tire. Solid Strip also protects the airtight tubeless system from being punctured in the case of a broken spoke. TCS 2.0 creates a more robust, easily installed and dependable tubeless system.Features: Material: Alloy Use: E-bike ETRTO: 27.5": 35-584; 29": 30-622 ERD: 27.5": 569; 29": 605 Hole Count: 32 hole, 6mm offset Inner Width: 30mm Brake Type: Disc Tubeless Ready: Yes, TCS tubeless Single or Pair: Single rim Manufacturer's Part Numbers: 27.5": W020-0601; 29": W020-0602 Weight: 27.5": 678g; 29": 718gBuy WTB Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
