Optimal Performance with Road Bike Derailleurs and Mountain Bike Derailleurs
Your bike relies on both front and rear derailleurs to seamlessly move the chain between cogs. These essential components determine your gear ratios, enabling you to achieve maximum speed by placing the chain on the largest front sprocket and smallest rear sprocket. Conversely, for easier uphill pedaling, the lowest ratio is attained by positioning the chain on the smallest front sprocket and largest rear sprocket.
