The new 22.5mm wide Cross Country specific XR 1501 SPLINE® ONE comes with all the advancements of a modern Cross Country rim, only at 2.5mm more width - providing more air volume for the same size tire which creates more traction and comfort. The asymmetric rim further improves spoke angles, making the wheel even stiffer, more precise handling and more responsive.

New rim profile - wider and lighter.
SPLINE® ONE wheels feature a unique rim profile that addresses the trend for wider rims in a lightweight package, but still remains durable. All wheels feature rim profiles engineered specifically to maximize the rim's material across all categories of weight, width and performance.
All SPLINE ONE wheels are designed to be tubeless ready with the use of our tubeless rim tape. The rims have been carefully engineered to feature a profile that minimizes the forces applied on the rim sidewall. This optimized rim bed yields fast tire installation, and a great tire fit, allowing for quick and trouble-free tubeless setup.
Straight pull spokes
SPLINE® wheels use high precision straight pull spokes for the perfect strength to weight ratio. Stronger than conventional spokes, they are still true- and replaceable with standard tools.
Pro Head® Reinforcement System (PHR system)
Due to it's larger and more spherical contact area, the new PHR system is designed to balance the loads transferred to the rim. Working in conjunction with the rim's design, the PHR system acts as a ball and socket interface allowing the spoke to pivot and follow the perfect trajectory from the hub to rim. Overall, this system allows for consistency throughout the build process, easy wheel truing and reduced spoke breakage.
DT Squorx nipple
The newly developed Squorx nipple (short for Square-Torx nipple), is a part of the Pro Head® Reinforcement System and provides a precise fit between the nipple and wrench. This dual purpose design allows for increased precision during wheel building at the factory and service due to the torx interface on top. For convenience, Squorx nipples also feature a standard square interface at the bottom for adjustment anytime using a standard square nipple wrench.
Two-piece hub body
All SPLINE ONE wheels feature a unique hub shell that is forged through two separate techniques. This process allows us to optimize the hub shell design, maintain structural integrity and reduce overall weight without sacrificing strength. The end result is a hub shell that appears seamless in nature and special in design.
The SPLINE® hub shell design and straight pull spokes allow for an optimized position of the spoke anchor points, creating a stiffer, more responsive wheel.
Due to the shape of the spoke anchors, spoke pull has only minimal effects on the bearing seats, which in turn considerably increases bearing longevity.
SPLINE® hubs are optimized for their respective lacing pattern. This ensures that the spokes align with mathematical precision so that material use is minimized for the best strength to weight ratio. More
Proven freewheel technology
The patented DT Swiss Ratchet System® is known throughout the world for it's reliability, efficiency and long-lasting performance. Each series of SPLINE ONE wheels feature our 36 tooth ratchets, with 10 degrees of quick engagement. This faster engagement allows for increased, more positive power transfer under load and higher performance in technical situations.
The maximum recommended system weight is 110 kg.
