{"title":"Leader","description":"\u003cp\u003eThe selection listed under Leader includes an 18-tooth single gear for children's bicycles. This product is intended for replacing a specific part in the bike's drivetrain system. Although the gears used in children's bikes look similar externally, they may differ in connection design and chain size. Therefore, the choice should not be made solely based on the wheel diameter or age range but should be verified against the existing part.\u003c\/p\u003e\n\u003ch2\u003eHow to choose Leader products?\u003c\/h2\u003e\n\u003cp\u003eBefore purchasing an 18T single sprocket, determine the tooth count and the hub connection type of the part to be removed. The current chain width, the body's structure, and the chain line are also important for compatibility. The term children's bike in the product title does not guarantee compatibility with all children's models. Compare with a photo or measurement of the old sprocket; if you change the tooth count, note that pedaling feel and chain length may be affected.\u003c\/p\u003e\n\u003ch2\u003eProduct samples from the collection\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e\u003ca href=\"\/en\/products\/leader-cocuk-bisikleti-tekli-disli-18t\"\u003eLeader Kids Bicycle Single Gear 18T\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions about Leader\u003c\/h2\u003e\n\u003ch3\u003eDoes Leader 18T gear fit every child's bicycle?\u003c\/h3\u003e\n\u003cp\u003eNo. Besides the number of teeth, the connection type, chain width, and compatibility with the current hub must be checked.
