The Nevegal X features slightly lower shoulder lugs and more aggressive center line than the original for a more well rounded smoother rolling tire. EMC - is the first tire casing on the market specially designed to meet the requirements of e-mountain bikes and offer an additional layer of puncture protection. DTC - Dual Tread Compound is a combination of two different rubber compounds L3R Pro (center knobs) and Stick-E rubber (corner knobs). TLR/TR - Tubeless (Light) Race is the lightest tubeless ready version of tires Kenda offers and also features an improved bead shape for better retention.
