DT Swiss HXC 1501 Spline® LS 27.5" 30mm CL Boost Rear wheel
Thanks to the low weight carbon rims, riders benefit from increased agility and dynamism when going uphill and downhill, while withstanding the increased torques of eMTBs. The spokes were designed with specific diameters to align light weight and resistance. Inside the 240 hub, oversized bearings support the additional loads of eMTBs. With the Ratchet EXP OS system, the rider benefits from direct acceleration through a torque-resistant freehub system. Each component has been designed with the specific aim of delivering advanced agility to find flow and fun on the trails.

CARBON RIMS HXC 1501 SPLINE ONE LS
The ultimate model of the Hybrid MTB LS range is equipped with carbon rims with an internal width of 30 mm. These wheels provide outstanding agility due to their low weight, while being strong enough to provide lasting trust on each trail. Their agility allows them to quickly climb fast technical uphills and come back down on demanding lines that require dynamism from the rider and their bike.
LIGHTER HYBRID SPOKES
With spokes thicker than those for MTBs, but thinner than those for eMTBs, the Hybrid MTB LS spokes ensure increased lateral and torsional stiffness compared to normal MTBs, without having a significant impact on the weight. Increased lateral stiffness is better suited to the additional light eMTB loads, while the enhanced torsional stiffness enables more direct power transmission from the hub to the rim. Furthermore, each spoke is always loaded and unloaded during a wheel rotation. The continuous loading and unloading leads to fatigue behavior of the spoke, which is improved by the thicker diameter.
ADAPTED HYBRID HUBS
Although the battery and motor are smaller, they still add extra weight compared to traditional MTBs. Lightweight eMTBs are often ridden the same way as traditional enduro bikes, adding extra loads to the components. For these reasons, the hub body has been redesigned. It allows for increased resistance to higher drive torques from motors and heavier brakes torques from additional weight, increasing its reliability, without compromising its lightness.
REINFORCED BEARINGS
Grooved ball bearings are usually found in high-end bicycle hubs. These bearings have been optimized to spin fast and absorb radial forces while still being able to take up a certain number of axial forces. Bearing wear occurs when the forces on the balls or on the running surface are too high. The high local loads can lead to indentations in the running surface, which causes the balls to no longer run smoothly. Excessive point loads can also lead to abrasion of the running surface, which can result in play. Given the greater loads on eMTBs, adjustments to the ball bearings are also required. Accordingly, the new generation of hybrid wheels use larger ball bearings than the 240 EXP MTB hub. The larger ball bearings distribute loads over a larger area of the running surface, whereby less wear occurs.
