Features<t_OriginalText> : </t_OriginalText>The large guide wheel design features a large-size 15-tooth tension wheel and a 13-tooth guide wheel, which reduces noise and wear. The SMARTCAGE guide wheel plate uses 13- and 15-tooth components.The guide wheel allows a shorter chain cover, enabling operation of the MEGARANGE transmission system. The width ratio is the same as that of the transmission system and the 3/4 gear sprocket. The SMARTCAGE guide wheel plate not only improves the appearance of the bicycle but also increases the ground clearance and enhances its passing capability. The advanced easy-to-operate design, low-friction connections, and low-tension stretch springs significantly reduce the switching force required by the chainring, regardless of the position of the teeth. The low-friction connection pivot sleeve reduces friction.
