The Arch S2 [paid link] from Stan’s NoTubes is a popular choice for riders seeking a high-performance, tubeless-ready wheelset designed for both cross-country and trail riding. Like any bike component, regular maintenance is essential to ensure the Arch S2 [paid link] wheels continue to perform at their best. This guide will cover the steps for installing, adjusting, maintaining, and troubleshooting the Arch S2, along with customization options and comparisons with similar models.

Installation of the Arch S2 Wheels

Installing the Arch S2 wheels requires careful attention to detail. Proper installation ensures optimal performance, safety, and longevity.

Step-by-Step Installation

1. Prepare the Hub and Rim
   Ensure the hub is properly lubricated before installation. This prevents friction and premature wear. Clean both the hub and rim to remove any dirt or grease.
2. Install the Tire
   Begin by mounting your preferred tire onto the rim. The Arch S2 rims are tubeless-ready, so ensure that the tire is properly sealed by using a tubeless-compatible tire. Apply some soapy water to help the tire bead seat smoothly.
3. Add Tubeless Tape and Valve
   If your wheels are not already pre-taped, you’ll need to install tubeless tape over the rim bed. Cut the tape to the correct length, and apply it evenly around the rim. Afterward, install the tubeless valve stem through the valve hole in the rim.
4. Inflate the Tire
   With the tire in place and the valve installed, inflate the tire using a high-volume pump or compressor. Ensure that the tire bead seats correctly, and the tire is inflated to the recommended pressure.
5. Check for Leaks
   Once the tire is inflated, check for any air leaks around the valve and rim. If you notice any leaks, reseat the tire bead or use some sealant to help form an airtight seal.
6. Install the Wheel on the Bike
   After the tire is fully inflated, install the wheel onto your bike, ensuring that the axle is properly tightened and aligned with the frame or fork.

Adjustment and Maintenance of the Arch S2 Wheels

Proper maintenance of the Arch S2 wheels ensures they remain in top condition and perform well over time. Key adjustments and maintenance steps are needed periodically to keep the wheels functioning smoothly.

Truing the Wheels

Over time, the wheels may become slightly out of true due to impacts from rocks, curbs, or rough terrain. To true your wheels:

1. Remove the Wheel
   Use a quick-release or thru-axle mechanism to remove the wheel from the bike.
2. Check for Wobble
   Use a truing stand to check for any lateral or radial wobble in the rim. Rotate the wheel and observe where it deviates from true.
3. Adjust the Spokes
   Using a spoke wrench, tighten or loosen the spokes in the affected area to correct the wobble. It’s important to make small adjustments gradually, checking the trueness after each turn.
4. Recheck and Install
   After making the necessary adjustments, recheck the wheel for true. Once satisfied, reinstall the wheel on the bike.

Lubricating the Hub

The Arch S2 hub requires regular lubrication to ensure smooth operation. Lack of lubrication can lead to increased resistance and premature wear. Here’s how to maintain it:

1. Remove the Hub from the Wheel
   Remove the wheel from the bike and detach the hub. Clean the hub free of dirt and old grease.
2. Disassemble the Hub
   Depending on the hub design, remove the axle and freehub body. Refer to your specific hub manual for disassembly instructions.
3. Apply New Grease
   After cleaning the components, apply a thin layer of high-quality grease to the bearings and freehub body. Ensure all moving parts are well lubricated.
4. Reassemble the Hub
   Reassemble the hub by reversing the disassembly process. Ensure all parts are properly aligned and securely tightened.
5. Install the Hub Back into the Wheel
   After reassembling the hub, reinstall it back into the wheel and check the operation. Spin the wheel to ensure smooth and free movement.

Maintaining Tubeless Setup

To maintain the tubeless setup of the Arch S2 wheels, it’s essential to keep the sealant in good condition. Sealant tends to dry out after a few months of use, requiring periodic replacement or topping off.

1. Remove the Valve Stem
   Use a valve tool to remove the valve stem from the wheel.
2. Check Sealant Condition
   Inspect the sealant inside the tire. If it has dried or clumped, it’s time to replace it.
3. Add Fresh Sealant
   Add the appropriate amount of tubeless sealant into the tire through the valve. You may need to rotate or bounce the wheel to help the sealant spread evenly across the tire.
4. Reinstall the Valve Stem
   After adding the new sealant, reinstall the valve stem and re-inflate the tire.
5. Check for Leaks
   Once the tire is inflated, check for any leaks around the valve and rim. If necessary, reseat the tire or add more sealant.

Troubleshooting Common Set-Up Issues

While the Arch S2 is a reliable wheelset, users may encounter a few common issues that can be easily addressed with some basic troubleshooting.

Tire Bead Seating Problems

If the tire bead is not seating correctly, this may result in air leakage or improper inflation. To resolve this:

• Increase the Pressure: Use a high-volume pump to quickly inflate the tire, which may help the bead seat properly.
• Check for Obstructions: Ensure that no debris or foreign objects are obstructing the bead’s contact with the rim.

Leaking Sealant

If you notice that the tire is losing air despite using a tubeless setup, there may be a sealant leak. To fix this:

• Inspect the Rim and Tire: Look for cracks or holes in the rim or tire that may be allowing air to escape [paid link].
• Reapply Sealant: If the sealant has dried or clumped, replace it with fresh sealant and re-inflate the tire.

Wobbling or Untrue Wheels

A common issue after rough rides is the wheel becoming out of true. If you notice a wobble:

• Use a Truing Stand: Adjust the spokes to restore the wheel’s true shape.
• Inspect for Damage: Check the rim for cracks or severe damage that may require replacement.

Customization and Optimization for Better Performance

The Arch S2 wheels are highly customizable, allowing riders to optimize their setup for specific performance goals. Here are some tips for customizing and enhancing the performance of your Arch S2 wheels:

• Choose the Right Tires: Select tires that match the terrain you ride on. For cross-country riding, lightweight tires with low rolling resistance work best, while for trail riding, consider slightly wider, grippier tires.
• Adjust the Pressure: Fine-tuning your tire pressure can drastically improve performance. Lower pressures offer more grip and comfort on rough trails, while higher pressures provide faster rolling and efficiency on smoother surfaces.
• Upgrade the Hub: Consider upgrading the hub for improved engagement and smoother performance. A hub with a higher number of engagement points will give you quicker power transfer, which is especially beneficial on technical terrain.

Comparison with Similar Models

When choosing a wheelset, it’s important to consider other models that may offer similar performance features. Compared to other mid-range wheels, such as the Shimano XT or DT Swiss XM 1501, the Arch S2 excels in:

• Tubeless Setup: The Arch S2’s tubeless-ready design makes it easy to set up and maintain for a smoother ride.
• Weight: The Arch S2 is a lightweight option compared to others in the same price range, making it a strong contender for performance-oriented riders.
• Durability: While not as heavy-duty as downhill models, the Arch S2 offers a good balance of strength and weight, making it ideal for cross-country and trail use.

Compatibility with Other Drivetrain Components

The Arch S2 wheels are compatible with most modern drivetrain systems, including Shimano and SRAM. To ensure compatibility:

• Axle Type: The Arch S2 supports both quick-release and thru-axle setups, so make sure the wheels match your bike’s axle specifications.
• Hub Compatibility: Ensure that the hub fits with your bike’s cassette body. The Arch S2 uses a standard freehub, compatible with 8-11 speed drivetrains.

Regular maintenance and proper installation of your Arch S2 wheels will ensure they perform at their best for years. By following the steps outlined in this guide, you can easily troubleshoot any issues, customize the wheelset to your needs, and keep it in optimal condition for a smooth, efficient ride.
