  • 15mm wrench
  • Torque wrench [paid link]
  • Cassette removal tool
  • 5mm Allen wrench [paid link]
  • Spoke wrench
  • Tire levers
  • Rim tape
  • Tubeless valve stems (if installing tubeless tires)

Installation of the ARC Offset 30 Wheels

Preparing the Hub and Rim

Before installing the ARC Offset 30 wheels, make sure the hub and rims are clean and free of any dirt or debris. This ensures a secure installation. If you are using a tubeless setup, make sure the rims are properly taped and ready to hold air. The wheels are compatible with both tubeless and traditional inner tube setups, depending on your preference.

Mounting the Wheels

  1. Front Wheel: Insert the front wheel into the fork dropouts. Make sure it is aligned correctly. Tighten the quick release or thru-axle to secure the wheel in place, ensuring the wheel spins freely without wobble.
  2. Rear Wheel: Insert the rear wheel into the dropouts, ensuring that the cassette side is facing outward. Tighten the quick release or thru-axle. Be sure to adjust the wheel’s alignment, ensuring it sits straight in the frame.

Installing the Cassette (for Rear Wheel)

  1. Remove the existing cassette using the cassette removal tool.
  2. Install the new cassette on the freehub body. Tighten it securely with the cassette tool and torque wrench [paid link] to prevent slippage.

Tire Installation

  1. Insert your selected tire onto the rim, ensuring that the tire bead sits securely inside the rim walls.
  2. If using tubeless tires, install tubeless valve stems and add tire sealant before fully seating the tire.
  3. Inflate the tire, making sure it seals properly and holds air without leaks.

Final Checks

Ensure that the wheels are properly secured, with no rattling or loose components. Spin the wheels to confirm they are true and spin freely.

Adjustment and Fine-Tuning of the ARC Offset 30

Spoke Tension and Wheel Trueing

One of the key features of the ARC Offset 30 is its high spoke tension, designed for durability on rugged [paid link] trails. After installation, it’s important to check the spoke tension and wheel trueness regularly to ensure optimal performance. Use a spoke wrench to tighten or loosen spokes as necessary to keep the wheel true.

  1. To check for wheel trueness, rotate the wheel while looking at the rim. Any wobble indicates the need for spoke adjustment.
  2. Tighten the spokes evenly across the wheel. This helps maintain the offset design and ensures the rim stays straight.

Brake Rotor Alignment

When adjusting the brake rotors, check that the rotors are aligned with the brake pads. Misalignment can cause rubbing, which reduces braking efficiency. Adjust the rotor spacing using the appropriate tools if necessary.

Hub Adjustment

If you experience any play or resistance in the wheel, check the hub. The Race Face ARC Offset 30 features an adjustable preload system to ensure smooth rolling. Adjust the hub as needed by tightening or loosening the preload nut to maintain proper bearing tension.

Maintenance of the ARC Offset 30 Wheels

Regular Cleaning and Inspection

To maintain peak [paid link] performance, clean the wheels regularly. Use a mild detergent and a soft cloth to wipe down the rims and hubs. Inspect the rims for any cracks, dents, or damage after each ride, especially after high-impact trail sections.

Lubrication of Hubs and Bearings

Lubricate the hub bearings every 50 to 100 hours of riding. This helps reduce friction and ensures smooth operation. Use a high-quality bike grease for this task. Check the hub’s freehub body for wear, especially if you notice a decrease in engagement performance.

Tubeless Tire Maintenance

If you’re running tubeless tires, check the sealant levels regularly and top off as needed. Sealant can dry out over time, reducing its effectiveness in sealing punctures. Also, inspect the valve stems for any signs of leakage or wear.

Troubleshooting Common Set-Up Issues

Issue: Wheels Not Seating Properly

If the wheels don’t seat properly in the dropouts, check for any debris in the fork or frame dropouts that could prevent a smooth fit. Clean the dropouts and try reinstalling the wheels.

Issue: Brake Rub or Poor Braking Performance

Brake rub often occurs when the rotor is slightly misaligned. Ensure that the rotor is properly centered between the brake pads. If needed, re-align the brake calipers and tighten the bolts securing the rotor.

Issue: Wheel Wobble

If you notice a wobble after installation, it is likely due to improperly tensioned spokes. Check the spoke tension and make adjustments as necessary to bring the wheel into true. For more severe issues, consult a professional wheel builder.

Customization and Optimization for Better Performance

Upgrading to a Higher Engagement Hub

For riders seeking more instantaneous power transfer, consider upgrading the hub to one with a higher engagement ratchet system. This modification enhances the performance of the ARC Offset 30 wheels, especially on technical trails where quick responses are critical.

Tire Selection

The ARC Offset 30 wheels are designed to handle a wide range of tires, from fast-rolling XC options to more aggressive trail tires. Selecting the right tire for your riding style and terrain can significantly affect the overall performance of your bike. Choose wider tires for more grip on rough trails or narrower tires for speed and efficiency on smoother surfaces.

Weight Optimization

While the ARC Offset 30 wheels are built for strength, there are ways to further optimize the weight. Lighter tires, tubeless setup, and a high-engagement hub can reduce weight without sacrificing performance.

Comparison with Similar Models

When comparing the ARC Offset 30 to other wheels in its category, such as the DT Swiss XM 1501 and the Industry Nine Enduro 305, the ARC Offset 30 stands out due to its unique offset rim design. This design enhances spoke angle and wheel durability, providing better performance on rough terrain.

  • DT Swiss XM 1501: While the XM 1501 is an excellent all-around wheel, the ARC Offset 30 offers a more aggressive, wider rim profile, which is better suited for mountain biking on more challenging trails.
  • Industry Nine Enduro 305: The Industry Nine wheels have higher engagement hubs, but the ARC Offset 30 excels in spoke tension and the ability to handle higher loads, making it a better option for heavier riders or those pushing their bikes on technical trails.

Compatibility with Other Drivetrain Components

The ARC Offset 30 wheels are compatible with most modern drivetrain components, including SRAM and Shimano drivetrains. Their wide rim profile and increased spoke tension are designed to handle higher torque loads, which is essential for MTB riding. Ensure that your cassette and freehub body are compatible with the wheel’s freehub system, and check the axle type to ensure compatibility with your frame and fork.

By ensuring proper installation, adjustment, and maintenance, the ARC Offset 30 wheels can provide long-lasting, high-performance riding, even under the toughest conditions.
