The XM 1501 SPLINE 30 is incredibly versatile. Combined with a wide tyre, it offers full traction even on the toughest descents. This ensures that you'll make the toughest climbs. Designed for demanding all-mountain riders, the XM 1501 SPLINE 30 is based on our downhill World Cup and EWS proven rim construction. DT Swiss quality in wheel construction as well as the unique Ratchet System hubs complete a product that dominates the mountain.
RATCHET SYSTEM Technology
The patented freewheel system with high-precision toothed pulleys guarantees maximum load capacity and reliability. Thanks to the no-tool concept, the system is very easy and quick to maintain.
In the Pro Lock process, a patented two-component adhesive is injected into the nipple thread, allowing the construction of extremely durable impellers. As soon as the nipples are screwed in, the adhesive is activated and cures completely at room temperature after approx. 6 - 7 hours. Repeated re-centering is possible without problems, whereby the adhesive strength decreases slightly with each re-centering.
Tubeless Ready rims from DT Swiss have further advantages over conventional rims. Thanks to the design of their cross-section, the tyre simply pops into place when inflated, so that in most cases only a normal floor pump is required. The ingenious profile of the DT Swiss rims also ensures a precise and secure fit for the tyre, even under tough driving conditions.
PHR - Pro Head Reinforcement system. The PHR system increases the load-bearing surface of the nipples on the rim and reduces local loads. Peak loads are reduced so that DT can build the rim even lighter. The shape of the disc also acts as a ball joint and automatically aligns the specific DT Squorx Pro Head ball nipples with the spoke, reducing the risk of spoke breakage or rim cracking.
