The DT Swiss EXC 1200 SPLINE [paid link] wheels are designed with mountain bike (MTB) enthusiasts in mind, offering a balance of lightweight construction, durability, and superior performance. These wheels are engineered for riders who demand high performance in challenging terrains, whether on rugged [paid link] trails or aggressive downhill sections. In this guide, we will explore the installation, adjustment, maintenance, troubleshooting, and optimization of the EXC 1200 SPLINE [paid link] wheels, as well as their compatibility and comparison with other MTB wheels.

Features of the EXC 1200 SPLINE Wheels

The DT Swiss EXC 1200 SPLINE wheels are equipped with several advanced features that make them ideal for MTB enthusiasts:

  • Tubeless-Ready Design: This feature enhances comfort and performance by allowing riders to run lower tire pressures, reducing the risk of pinch flats.
  • Spline Technology: The EXC 1200 SPLINE wheels feature DT Swiss’s unique Spline technology, offering a combination of strength, stiffness, and low weight. This design optimizes power transfer and responsiveness on the trail.
  • Carbon Fiber Rims: The rims are constructed from high-quality carbon fiber, ensuring durability and low weight. Carbon also provides better shock absorption, which is essential for tackling rough terrain.
  • Ratchet System: The wheels use the DT Swiss ratchet system for efficient and quick engagement, contributing to better acceleration and smoother riding.

These attributes combine to deliver an MTB wheelset that can handle technical climbs, descents, and rough terrain with ease.

Tools Required

Before installing or performing maintenance on the EXC 1200 SPLINE wheels, you will need the following tools:

  • Torque wrench [paid link]
  • 5mm and 6mm hex wrenches
  • Presta valve core tool (if necessary for tubeless setup)
  • Rim tape (if setting up tubeless tires)
  • Tubeless sealant
  • Spoke wrench
  • Disc brake rotor tool (if changing rotors)

Installation of the EXC 1200 SPLINE Wheels

The installation process of the EXC 1200 SPLINE wheels is straightforward, but care must be taken to ensure proper setup for optimal performance.

  1. Remove the Old Wheelset: If you’re replacing an existing wheelset, start by removing the old wheels from the bike. Use a 5mm hex wrench to remove the quick-release or thru-axle, depending on your bike’s specifications.
  2. Install the New Wheelset: Place the EXC 1200 SPLINE wheels into the dropouts or frame mounts, ensuring the wheels are centered. Tighten the axle or quick-release securely, following the manufacturer’s torque specifications.
  3. Install the Disc Brake Rotors: If your EXC 1200 SPLINE wheels do not have disc rotors installed, use a disc brake rotor tool to securely mount the rotors onto the hubs. Be sure to follow the recommended torque settings.
  4. Set Up Tubeless Tires (Optional): The EXC 1200 SPLINE wheels are tubeless-ready. If you’re setting up tubeless tires, apply rim tape to ensure an airtight seal. Install the tires, add tubeless sealant, and inflate to the recommended pressure. Check for leaks and make sure the tire bead is seated correctly.
  5. Check the Cassette Installation: Ensure the cassette is correctly installed onto the freehub body. Use a lockring tool [paid link] to tighten the cassette securely.

Adjustments for Optimal Performance

While the EXC 1200 SPLINE wheels are designed for top-tier performance right out of the box, some adjustments may be required to fine-tune them for your riding style and conditions.

  1. Spoke Tension: Over time, spoke tension can change due to use. If you notice any rim wobble or feel that the wheels are not rolling as smoothly, use a spoke wrench to adjust the tension on any loose spokes. Ensure the spokes are tensioned evenly for optimal wheel performance.
  2. Hub Engagement: The ratchet system on the EXC 1200 SPLINE wheels provides rapid engagement, but if you notice that the engagement feels slow or inconsistent, it may be a sign that the freehub needs lubrication. Disassemble the hub, clean the internals, and apply fresh grease to the ratchet mechanism.
  3. Brake Rotor Alignment: When installing or replacing the brake rotors, ensure that they are aligned properly with the calipers. Misalignment can cause rubbing and reduced braking performance. Use a rotor tool to make sure the rotor is mounted correctly.

Maintenance and Care

To ensure the longevity and performance of the EXC 1200 SPLINE wheels, regular maintenance is essential.

  1. Clean the Wheels: After every ride, it is important to clean the wheels to prevent the build-up of dirt, mud, and debris. Use a soft brush and mild soapy water to clean the rims and hubs. Avoid using harsh chemicals that can damage the carbon fiber rims or hubs.
  2. Inspect the Hubs: Periodically, check the hubs for any signs of wear or unusual noise. If the bearings feel rough or there is excessive play, it might be time to service or replace the bearings. Follow the manufacturer’s instructions for bearing maintenance.
  3. Check for Cracks or Damage: As with any carbon fiber components, it’s essential to regularly check the rims for any cracks or signs of damage. Any noticeable cracks or damage should be addressed immediately, as they can compromise the strength and safety of the wheels.
  4. Maintain Tubeless Setup: If you’re using the wheels in a tubeless setup, check the tire pressure regularly and top off the sealant as needed. The sealant can dry out over time, which can result in poor sealing and potential leaks.

Troubleshooting Common Set-Up Issues

Even with high-quality components like the EXC 1200 SPLINE wheels, some common issues may arise during setup. Here are some troubleshooting tips:

  • Wheel Wobble: If you experience a wobble or uneven spoke tension, check the spoke tension using a spoke wrench. If the wheels are still out of true, it may be necessary to take the wheels to a professional mechanic for truing.
  • Poor Engagement: If the ratchet system is slow or noisy, it may need cleaning and re-lubing. Open the freehub body, clean out old grease, and apply fresh lubricant to the ratchet mechanism.
  • Brakes Rubbing: If your disc brakes are rubbing against the rotor, check the alignment of the rotor and brake caliper. You may need to adjust the position of the calipers or re-align the rotor for smooth braking.

Customization and Optimization

For riders looking to maximize the performance of the EXC 1200 SPLINE wheels, there are a few customization options to consider:

  1. Tire Choice: The type of tires you use can significantly impact the performance of the wheels. For maximum traction, consider wider tires for rough trails or narrower ones for speed on smoother surfaces. Tubeless tires offer the best performance and comfort when paired with these wheels.
  2. Cassette Selection: Choose a cassette that suits your riding style. If you’re into aggressive mountain biking, a wider-range cassette may offer better gearing for steep climbs and fast descents.
  3. Hub Upgrades: For even faster engagement, consider upgrading the freehub to a higher-end model, if available. Some riders may prefer a different hub design for personal preference or specific riding conditions.

Compatibility with Other Drivetrain Components

The EXC 1200 SPLINE wheels are compatible with a wide range of drivetrain components, including Shimano and SRAM systems. The freehub body is available in both Shimano/SRAM and XD driver options, so you can easily match it to your preferred drivetrain. Additionally, the wheels are designed to work with both standard 6-bolt and Center Lock disc brake systems, offering flexibility depending on your bike’s setup.

Comparison with Other MTB Wheels

Compared to other MTB wheels in the same price range, the EXC 1200 SPLINE wheels stand out due to their carbon fiber construction and Spline technology. While some competitors offer lightweight wheels, the EXC 1200 SPLINE wheels excel in stiffness, power transfer, and durability. If you’re looking for a balance of speed, strength, and comfort, the EXC 1200 SPLINE wheels are a solid choice.

Other brands may focus more on affordability or lightweight designs, but the EXC 1200 SPLINE wheels offer a level of performance that is hard to match, particularly for riders who need reliable and long-lasting wheels for aggressive riding. Whether you’re a cross-country racer or a downhill enthusiast, the EXC 1200 SPLINE wheels provide the durability and precision required for competitive mountain biking.
