Schwinn created the ultimate exercise machine, when they put the Schwinn Airdyne Exercise bike on the market in the late 1970's. It has since become the most common form of fitness as far as exercise bikes. The Airdyne has no resistance parts, and gets all its resistance from air.
These bikes have been around since the late 70's and since that time replacement parts have remained basically the same. They still use wedge pins in the crank arms, and a two crank system with a left and right eccentric arm. The grips have remained the same as well as the connecting arms, pivot bolts and lever arms.

The SR-12 Park Tool Chain Whip Freewheel Sprocket Remover is a combination of lock ring/freewheel remover wrench and a chain whip. The tool has been heat-treated to avoid flexing and bending. It also has a molded handle for additional comfort.
This tool will work on 5 - 12 speed freewheels and cassettes. The 1" box end wrench (25.4 mm) will fit the lock ring tool also made by Park Tool. It has pins that are hardened to make sure the chain won't move.
