Shimano Hyperglide Removal

Shimano Hyperglide chains are made to mesh with the Shimano Hyperglide cassettes. The cassette is also referred to as the sprocket or gear cluster. When removing the Hyperglide, you remove the chain and the cassette. Both require special tools proprietary to the portion of Hyperglide being taken off the bicycle. Use a bike stand to ensure access to the parts needed to be removed.

Instructions

    • 1

      Place the bike in the work stand and turn the pedals. Shift the gears while turning the pedals so the chain is on the smallest gear on the rear derailleur.

    • 2

      Stop the pedals and chain. Unscrew the chain tool--the chain tool looks like a small hand-held vise with a set of small jaws and a metal pin. Turn the handle to open the jaws and expose the pin. Slide the tool jaws onto the Hyperglide chain. Center the metal pin over one of the links in the Hyperglide chain.

    • 3

      Align the metal pin on the chain tool to one of the link pins. Turn the handle on the tool clockwise to lower the tool pin onto the chain pin, pushing it out of the link. The pin will fall to the ground when pushed out.

    • 4

      Separate the chain at the broken link where the tool pushed the pin out. Remove the Hyperglide chain from the bicycle.

    • 5

      Wrap the chain whip--a special bike tool that looks like a plastic ruler with a section of bicycle chain hanging off one end--around the large sprocket on the Hyperglide cassette. Place the adjustable wrench on the opposite side of the cassette wheel on the hub nut. With opposing force, twist the cassette until it loosens on the hub.

      Unscrew the Hyperglide cassette with your hands, removing each gear as it separates from the cassette and hub.
