The EX 1501 SPLINE One wheels come packed with features designed to enhance your cycling experience. Whether you’re riding on rugged [paid link] trails or smooth roads, these wheels offer a blend of strength, weight savings, and precision. Here’s what you need to know about them:
1. Robust and Lightweight Construction
The EX 1501 SPLINE One wheels are built with DT Swiss’ renowned SPLINE technology, which provides a balance between strength and weight. The rims are made of aluminum, which keeps the weight low while maintaining strength and durability. This makes them suitable for all types of cycling disciplines, from mountain biking to endurance riding.
2. DT Swiss Hub Technology
The EX 1501 wheels feature the DT Swiss 240s hubs, a crucial component in ensuring smooth and reliable performance. The 240s hubs are known for their durability and responsiveness, offering quick engagement that allows for faster acceleration and more efficient power transfer.

3. Straightpull Spokes
One of the standout features of the EX 1501 SPLINE One wheels is the use of straightpull spokes. Unlike traditional J-bend spokes, straightpull spokes offer increased wheel stiffness and a more direct power transfer. This design enhances the strength of the wheel, while also providing a more aerodynamic structure and reducing the likelihood of spoke fatigue.
4. Wide Internal Rim Profile
The EX 1501 wheels feature a wide internal rim profile that enhances tire performance, providing better traction and control, especially when riding on challenging terrain. The increased rim width allows for wider tires, which improves stability and comfort, while also reducing the risk of pinch flats.
5. Tubeless Ready
The EX 1501 SPLINE One wheels are tubeless ready, allowing riders to run their tires without inner tubes. This reduces rolling resistance, improves puncture resistance, and offers a smoother ride. Tubeless setups also allow for lower tire pressures, increasing grip and comfort without sacrificing speed.
Installation of the DT Swiss EX 1501 SPLINE One Wheels
Installing the DT Swiss EX 1501 SPLINE One wheels requires a few essential tools and a systematic approach to ensure they are set up correctly. Follow these steps for a smooth installation:
Tools Required
- 5mm Allen wrench [paid link]
- Torque wrench [paid link]
- Tire levers (for tubeless setup)
- Tubeless valve (if installing a tubeless tire)

Step-by-Step Installation Guide
- Prepare the Bike
Begin by ensuring that your bike is properly supported in a work stand. Remove the old wheels if necessary, and ensure the dropout spacing is compatible with the new wheels. - Install the Rear Wheel
Place the rear EX 1501 wheel into the rear dropout, ensuring the axle slides smoothly into place. Tighten the axle bolts using a 5mm Allen wrench [paid link] or a torque wrench [paid link] set to the manufacturer’s recommended torque specifications. - Install the Front Wheel
Insert the front wheel into the fork’s dropouts, making sure the wheel is aligned properly. Tighten the axle bolts as per the recommended torque specifications. - Tubeless Tire Setup
If you’re running tubeless tires, start by installing the tubeless valve in the rim. Apply the appropriate amount of tubeless tire sealant into the tire before mounting it onto the rim. Use tire levers to secure the tire bead and ensure it is properly seated in the rim channel. - Inflate the Tires
Inflate the tires to the recommended pressure, checking for any bead seating issues. Once the tire is fully inflated, rotate the wheel and check the tire for even seating. Allow the sealant to distribute within the tire to fully seal the setup.
Adjustment and Maintenance of EX 1501 SPLINE One Wheels
Routine Maintenance
Proper maintenance of your DT Swiss EX 1501 SPLINE One wheels will ensure they remain in top condition for longer. Here are some essential maintenance tips:
- Clean Regularly: Use a soft cloth and mild detergent to clean the rims, spokes, and hubs. Avoid using harsh chemicals that could damage the finish of the wheels.
- Check for Cracks or Damage: Regularly inspect the rims for signs of damage or cracks. Look for any bends in the spokes and replace any damaged spokes promptly to prevent further damage.
- Lubricate Hubs: The hubs require periodic maintenance, including re-greasing the bearings and internal components. Ensure the seals are intact to keep dirt and moisture from entering the hubs.
- Monitor Tire Pressure: Regularly check tire pressure, especially if using a tubeless setup. Low tire pressure can cause unnecessary strain on the rims, while high pressure can increase the risk of a blowout.
Wheel Truing and Tensioning
If you notice any wobble or misalignment in the wheels, it may be necessary to true them. Use a spoke wrench to adjust spoke tension, ensuring the wheel is properly aligned and balanced.
Troubleshooting Common Set-up Issues
While the EX 1501 SPLINE One wheels are designed for easy installation and maintenance, riders may encounter a few issues during setup. Here are common problems and their solutions:
1. Hub Resistance
If the hub feels resistant to spinning, it may indicate an issue with the bearing lubrication. Remove the wheel from the bike, open the hub, and clean or replace the bearings as needed.
2. Difficulty Seating Tires (Tubeless Setup)
If you’re having trouble seating the tire bead when setting up a tubeless tire, try using a high-volume air compressor to achieve the initial pressure needed to seat the tire. Adding more sealant can also help with sealing the bead effectively.
3. Loose Spokes
Loose spokes can cause the wheel to become out of true and affect performance. Tighten loose spokes incrementally using a spoke wrench, checking frequently for proper tension and wheel alignment.
Customization and Optimization for Better Performance
To enhance the performance of your EX 1501 SPLINE One wheels, consider the following upgrades:
1. Upgrade the Hubs
Although the 240s hubs are already high-performing, some riders opt for the DT Swiss 180 or 350 series hubs for even faster engagement or higher durability. Consider this upgrade if you ride in harsh conditions or need faster acceleration.
2. Tire and Sealant Choice
Experiment with different tire and sealant combinations to optimize the ride feel. A wider tire setup can increase comfort and control, especially on rough trails, while a more aggressive tread can improve traction.
3. Weight Reduction
For riders looking to reduce the overall weight of their setup, consider swapping to a lighter tire, or upgrading to lighter spokes or a lighter rim. While the EX 1501 wheels are already relatively lightweight, there are options to shave off grams for more competitive setups.
