Setup and Installation

Proper installation is crucial for performance and safety. It is recommended that installation be performed by a qualified bicycle mechanic.

Pre-Installation Check

• Inspect the wheel for any shipping damage.
• Verify all components are present: wheel, axle adapters (if applicable), and any included hardware.
• Ensure compatibility with your bicycle's frame/fork, axle standard (15mm Thru x 110mm Boost), and brake system (6-Bolt Disc).

Axle Installation

1. Insert the 15mm thru-axle into your fork's dropouts.
2. Align the wheel with the fork dropouts and slide the thru-axle through the hub.
3. Tighten the thru-axle according to your fork manufacturer's specifications.

Brake Rotor Installation

The HTZ i35 wheel is designed for 6-bolt disc brake rotors.

1. Clean the rotor and hub mounting surface.
2. Align the 6-bolt rotor with the mounting holes on the hub.
3. Install the six rotor bolts, tightening them in a star pattern to the manufacturer's specified torque (typically 6.2 Nm). Use thread locker if recommended by the rotor manufacturer.

Tire Installation (Tubeless Ready)

This wheel is TCS 2.0 Tubeless Ready. For tubeless setup, you will need tubeless tires, tubeless valve stems (Presta), and tubeless sealant.

1. Ensure the rim tape is properly seated and free of damage.
2. Install the tubeless valve stem through the valve hole (Presta valve).
3. Mount the tubeless tire onto the rim, ensuring the bead is fully seated.
4. Add the recommended amount of tubeless sealant through the valve stem or directly into the tire.
5. Inflate the tire to seat the beads, listening for distinct pops.
6. Check for air leaks and rotate the wheel to distribute sealant.

Operating Guidelines

The WTB HTZ i35 Front Wheel is designed for aggressive trail riding on e-assist mountain bikes. Adhere to recommended tire pressures and regularly inspect the wheel for optimal performance.

Tire Pressure

Refer to your tire manufacturer's recommendations for appropriate tire pressure. Lower pressures are often used for tubeless setups to enhance grip and comfort, but avoid pressures that could lead to rim damage from impacts.

Braking Performance

The HTZ hub's heat sink helps manage heat generated during braking, especially with larger rotors. Ensure your brake system is properly bled and pads are in good condition for consistent braking performance.

Maintenance

Regular maintenance extends the life and ensures the safety of your WTB HTZ i35 Front Wheel.

Cleaning

• Clean the wheel with mild soap and water after each ride, especially after riding in wet or muddy conditions.
• Avoid high-pressure washers directly on bearings or seals.
• Dry thoroughly with a soft cloth.

Bearing Inspection

• Periodically check the hub bearings for play or roughness.
• The double-stacked Enduro sealed bearings are designed for durability, but replacement may be necessary if wear is detected. Consult a professional mechanic for bearing service.

Spoke Tension and Truing

• Regularly check spoke tension. Uneven tension can lead to wheel damage or failure.
• If the wheel is out of true (wobbles side-to-side) or has flat spots, have it trued by a qualified mechanic.

Tubeless Sealant Refresh

• Tubeless sealant dries out over time. Check and refresh sealant every 2-6 months, or as recommended by the sealant manufacturer.
