    Among the vast assortment of bike parts that we offer are front derailleurs, rear derailleurs, clamps, guards, and other road bike derailleur items. Look through our list below to find the right bike part to keep you rolling.

    The modern road bike derailleur is a masterpiece of design simplicity that does so much with so few moving parts. Somewhat comparable to a motorized transmission, your typical rear wheels or front derailleurs move the drive chain over the gear sprockets.

    At Monster Scooter Parts, we want to be your source for genuine bike parts and accessories.
