Urban road tires perform well on paved surfaces and produce low tire noise, offering a quiet riding experience. These inner tubes are compatible with Zero 10X and Speedual models. When installed on Zero or Grace 10 models, the rear wheel fitment is ideal. However, on the front wheel, slight clearance issues may occur between the tire and f , potentially causing minor friction during use. Please note that due to narrow f s or swing arm design limitations, these tires may not fit models such as Dualtron 1/2, Inokim Fast 1/2/3, or Track 1/2/3/4, even if the wheel hub size appears compatible. Adequate space is required for wider tires, and installation on such models is not recommended. Tire installation and alignment require moderate technical skill and careful adjustment. Pneumatic tires provide significantly better shock absorption compared to solid tires. However, regular inflation is necessary to prevent the inner tube from being damaged by compression between the rim and outer tire.
