DT Swiss HX 1700 Spline® LS 27.5" 30mm Boost Front wheel
The 350 hubs have been redesigned for eMTB to offer more resistance to the acceleration and braking forces. In addition, the spokes have been modified to increase their strength without drastically increasing the weight. These wheels are ready to be ridden on the fastest lines in technical sections and to carve into fast and tight turns.

Technologies
ALUMINUM RIMS HX 1700 SPLINE LS
These wheels are equipped with light, welded aluminum rims to suit characteristics of light eMTBs: agility and reliability. The emphasis was put on the lightness of the rim to allow riders increased riding agility for those fast line changings on trails.
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.
