The DVO Onyx 38 D1 SL mountain bike fork redefines excellence in suspension performance. Engineered to deliver unparalleled steering precision, remarkable small bump sensitivity, and complete control, the Onyx 38 sets a new benchmark in MTB suspension technology.
With a distinctive E-Designed chassis and wider stance, complemented by robust 38mm stanchions, the Onyx 38 represents a significant leap forward in suspension innovation. Unlike conventional approaches that retrofit existing designs for e-bike compatibility, the Onyx 38 is purposefully crafted with an E-Specific design from the ground up.
E-Specific design means meticulously addressing the unique demands of e-bike suspension, ensuring optimal performance without compromise. By prioritizing factors like unitized flex, precise steering, and mitigating fore and aft flex, the Onyx 38 excels in both e-bike and regular bike applications.
