In an era of rising raw material costs and increasing environmental impact, this design focuses on material reduction and carbon footprint minimization. By rethinking the traditional chain whip structure, we introduce an innovative chain-free mechanism that securely holds the sprocket during removal. The adjustable pin accommodates mainstream 10T, 11T, and 12T sprockets, allowing users to operate intuitively by simply matching the first sprocket’s tooth count. This design enables faster and more stable operation without concerns of chain slippage or disengagement, just hook onto the sprocket.
